Petroleum Boiler : Tutorial nuggets : Oxygen not included

[@jasonslade6259]

14:00 For anybody watching this in 2023, you no longer need to use a tiny blob of liquid to make thermal contact in a Vacuum, because there's a new building called a "Conduction Panel" that will transfer heat to buildings in a vacuum. Just pump the incoming crude oil or outgoing petrol across it and you're good.

[@PerkyandSaggyVids]

Cycle 800 and I decided it's time I uncover the volcano I found 700 cycles ago. Turns out this single design would have solved my entire power crisis I've been struggling with for hundreds of cycles. Now I have SO much power and polluted water, I literally don't know what to do with it. Thanks for this design, turned my base from 6 dormant geysers killing me, and struggling to keep a constant pool of polluted water, to actually considering pumping polluted water into space to get rid of it

[@FrancisJohnYT]

How are you handling the CO2? You can run a lot of slicksters if you want the meat. Also welcome to the petroleum boiler club, you are going to find it hard not to tell everyone you meet to build one :) I know I do.

[@PerkyandSaggyVids]

@@FrancisJohnYT currently have all the slicksters I could find confined to a room with an open ceiling tile so they'll still reproduce and be kept wild, have like 15 in there at the moment, then I added rooms with mesh tile floors, a grooming station, and a storage box for moving the eggs so I could domesticate them. I've been pumping all my co2 from all my natural gas/petroleum generators down there with high pressure gas vents, and the whole oil biome is like 20 kg per tile of co2. I was running a test on a space build with regolith/steam turbine, build and let it run like 50 cycles, and last I looked I was up to 150kg per tile of co2 in the petroleum generator room lmao. Not even the slightest clue what to do with it. Guess I could use a nearby water geyser to carbon skim it for more polluted water, but I'm already thinking about sending it to space so I don't know. The room is currently sealed off, with the only entrance being a water lock and a tube access point. Short of turning my whole oil biome into slickster Haven, which wouldn't be possible without cracking more abyssalite than I want to, I'm kind of just considering letting the generator room be loaded with co2 since the pressure doesn't seem to matter. Any thoughts on a productive, non-slickster use for it?

[@julius.caesar.]

@@FrancisJohnYTI like the descriptor of “relatively indie” lol

[@PoringPoring951]

YAY!! Finally! interesting to know that there is really no calculation behind the length of the pipe, but a trial and error.

[@FrancisJohnYT]

Math's was tried, but the numbers don't add up. For example if you make a heat exchange stairs that only has one tile drops and only goes left the outputs will have a different temperature to the exact same stairs that only goes right. Madness like that resulted in the 12-16 tiles stair leg lengths with at least a two tile drop.

[@dpsilver1]

To be fair the calculations required for something lie this is not simple as each tile would not only experience a temperature decrease but the counter flowing fluid would increase and this would change over time. I have done some calculations for iron pipe boilers but I had to build one first

[@sirnavinod]

In regards to the aluminum based boiler using a full volcano, I found that with the temp settings set as they are in the save file, you will occasionally get over-pressure in the left bottom tile of the boiling point which causes the tile to leak some petroleum down into the vacuum side containing the magma tiles which causes an instant explosion of sour gas in the robo-miner vacuum. I found that raising the temperature in the petroleum boiling room by 2 degrees Celsius completely stopped the issue. Small tweak, I know, but it saved me a ton of pain from having to shut everything down and clean up the mess.

[@FrancisJohnYT]

Yeah I have had to up the temp on some designs depending on the map. I use 80C crude for testing, if the crude is cooler it can cause the issue you talked about.

[@sirnavinod]

@@FrancisJohnYT My crude is coming in at 108C and I was getting that issue. You had stated in this video that the aluminum versions were not as tested, since this came out not too long after they added aluminum. Maybe there is some ONI magic going on if you weren't having that issue with warmer crude oil. Thank you for making these videos, I find them to be an invaluable resource. You always try to find the simple, efficient way to accomplish your goals, without the over-engineering that ONI lends itself to so well.

[@Sarumann007]

I missed the building tutorial, and I was so paranoid about my doors not behaving like the ones in this video when bringing the boiler online, since I'm not that familiar with the automation. Ended up, after more time in thought than I want to admit, telling the magma-side thermo sensor function to "above 435" until the moment of activation, building the filter gate last, and then toggling the on switch at the same time as I set the magma sensor to "below" 435. I... Think it worked out. My robo-miner broke, though that was probably due to it running through 50 tonnes of oil before I changed the filter gate from the standard 5 second rule.

[@nohathatter5795]

This build almost broke me. From rerouting pipes to vacuuming out the space 4 different times, it took me about 11 hours to get it running. I kept missing little things and this game is all about the little things. Thank you for this tutorial and no offense, but I'm glad I don't need to watch it a 20th time :)

[@FrancisJohnYT]

Oh I get it, I have lost track of the amount of times I have broken my petroleum boilers and had to break into them to do a fix. Congrats on the boiler, may you enjoy swimming power and way to much CO2.

[@holysd]

First up, thanks for all the great nuggets! My experience with this boiler was a challenge as I went for the aquatuner version... No magma volcano, and cant easily crack open my magma biome without flooding it with salt water... Ran into some issues with priming it with the aquatuner. I couldn't get the chill from the aquatuner dumped with gold piping, especially while the crude oil was in the sub 400 temp range. I had to cycle the water out of the cold-box a couple of times to ensure it, and my super coolant didn't freeze. Also, the ´cooking' element with the tempshift plates was dumping a lot of heat into its surroundings without the magma feed part, as such it required double insulation. When I was about to call it quits and take a look at it in a couple of hundred cycles it was finally primed and started running like it was nothing. Thanks again, going to review this build at a later date, I feel like there might be some potential in all the chill that is now being used for cooling down that petrolium. Maybe slap a liquid oxygen facility onto it....

[@FrancisJohnYT]

Petroleum boiling is a gateway build, soon your freezing O2 and H2. But not long after that's not enough and you start boiling sour gas. Next thing you know your dropping an ocean on a magma biome just to see if it will boil :) Welcome to the deep end of the sand box, with everything you learned on petroleum boiling the next few thousand hours in this game are going to be so much fun.

just a Tiny littel hint for all of you out there… you Need steel for everything that is close to the magma even if you think that will never touch the magma itselfe. the heat will creap througth the wires and melt everthing!!! happend to me and had to reload a save that was 120 cycles back. lost my rocket and lost my hatchfarm :(

This is just the question I was going to ask.

[@ZielAmerak]

I little hint, if you don't need too much power there is 2 thing you can do. 1- once the system is running, limit the amount of crude oil that enter the system and replace some pipes with insulated to avoid the overheating, and the overpressure of the liquid. 2- burn the excess of petroleum to avoid the overpressure. if you let the pressure accumulate it could broke the tiles and the all thing will be a mess

I'm trying to keep the nuggets short, it's hard to do that and speak slow.

[@peterschneider127]

Great Tutorial. Build one in my survival playthrough and it's keeping my base alive. Never made it past cycle 600 before. Three things I would like to add: - I had problems when the heater got too cold. Crude oil rised up and made it's way through the cooling loop. I raised the temperature of the temperature sensor in the magma to 460°C and had no problem s so far (~200 cycles). - Petrolium Generators produce a significant amount of CO2. You can dump it somewhere and ignore for a while. But at some point you will hit 20kg/m² and things will get worse from there. For me, a massive amount of slicksters seems to solves the problem - Burn the heat the away of the petrolium boilers somehow. Learn the basic cooling builds.

[@FrancisJohnYT]

I pump the excess CO2 into space, well whatever the slicksters don't eat.

[@custume]

Made my 1º boiler ( follow your tut ), my is almost 100% equal to yours ( mine use aluminum ) and I have to say ... Works great, like really good, I don't use much petroleum because I normally have plenty of gas geysers and solar and found my self turning the boiler off ( yes I know you say is bad ) because I have no space to store so much petroleum ( TO MUCH PETROLEUM EHEHEHEHEHE ) I don't use it for food or water, also power is already check so your designed works so great that I had to turn it off ... Good one Francis, very good one, also great video

[@FrancisJohnYT]

The power of petroleum. Now try imagining you went straight from coal to petroleum bypassing gas and solar. You could get a volcanic or geothermal one up and running fairly early. Give it a go next run, I find it saves so much time because you put together your power one time your set for rest of the game.

[@custume]

@@FrancisJohnYT great advice, thank you 😃

[@chandl34]

These setups are great, but they take an eternity to set up. I've been working on getting one going in my current game for over 200 cycles. My volcano only erupts every 15 cycles 5 times, then goes dormant for 5 x 15 cycles. Still haven't had a chance to test it. If I could do it again, I would've opened up the volcano much earlier, with an automated door on a switch blocking the magma. That way, I wouldn't have to wait forever for the magma to fill in the area.

[@FrancisJohnYT]

If you want you can try using a pitcher pump to move magma from the magma biome to the boiler. It can be risky if the carying dupes get called to lunch but I have used that trick before to fill my boilers faster.

[@JayHann]

I approximately figured out part of the math for calculating the length of counterflow heat exchanger needed by setting the change in degree temperature equal to the heat flow into the pipe at each step: Given starting temp of say 80; ending temp of 403; thermal conductivities of 2(crude/petro) and 120(gold); specific heats of 1.69 and 1.76. (1.69*(403-80)*1000) / (L+1) = 1.76*[(120+2)/2]*50*dT This can be graphed with L as the x-axis length of the heat exchanger and dT as the y-axis representing the difference in heat at the end requiring magma heating. Multiplying the resulting dT by the mass (10,000g) and 1.69 yields the DTU required to be pulled out of the magma to maintain steady state constant operation. Note, the 1000 in "(403-80)*1000" is a conversion factor between kDTU and DTU. For example, a similar graph for aluminum is to replace the 120 value with 205. These graphs show a gold counterflow heat exchanger of length 56 is about equivalent to an aluminum one of length 36. (Note, heat does not exchange around certain bends). This appears to confirm what you have found empirically in your video. *PS, you have thermal bridging from the tempshift plate through the insulated igneous rock on the right side of your boiling chamber - this is good because it helps cool the petroleum ever so slightly so it doesn't damage that problematic last radiant pipe. ** You might want to note the materials used in the insulated tiles - obsidian around the magma but only igneous around the counterflow heat exchanger.

[@deanyearsley6126]

This is an amazing tutorial and I really thank you for putting it up. One issue I'm having though, is oxygen seems to magically appear in the vacuum chamber (the one with the gun), which eventually causes all kinds of heat issues and fixing this thing when it breaks is a nightmare.

[@FrancisJohnYT]

Assuming your liquid lock is keeping out gasses is the O2 sneaking in from the magma end?

[@deanyearsley6126]

@@FrancisJohnYT Magma end is still a vacuum and have 2x liquid locks on different parts of it. I've now double liquid locked the gun chamber, but still have 167mcg of oxygen in there. About 2 hours ago it was 600 mcg of oxygen, it seems to change. I'm totally baffled.

[@drakcoreoriginal]

You could build the robo miner at edge of the corner angled at the area you want to mine. So it will mine through that corner but still be outside of that vacuumed room. Just make sure you don't have anything directly on that corner such as a temp plate with magma :)

@Francis_John, I think I may have solved the pipes breaking occasionally in your petroleum boiler. I downloaded your save, made a blueprint, built it and sure enough just like you said the pipes 1 square down from the liquid vent and 1 square right started breaking and I had to break in and fix them. Funny enough, when I went to fix them my dupes left 15kg of aluminum on the ground on that exact spot and when the pipe was fixed some how exactly 2000g of crude oil was left there as well. At first it bothered me greatly I was worried I was going to have to tear it apart to fix it so I figured i'll just keep an eye on it to see if it still works. Well 250 cycles later I have never, not once gone back in for anything, the petroleum now climbs over the top of the 2000g of crude oil sitting just 1 square down and 1 square right from the liquid vent and this causes the heat to be evenly distributed and those pipes get up to 402ish but never the 406 or 408c that caused them to break and the 2000g of crude never flashes to petroleum. I have been running 10kg of crude through your aluminum/steel petroleum boiler for the past 250 cycles and the only thing I've had to do is make my petroleum tank bigger! :) Thanks and I hope this helps, would love to see this in your videos.

[@FrancisJohnYT]

That is the most getto fix that I have ever heard of, I cant believe that is still working after 250 cycles. Looks like that is your oil boiler now :)

[@jej3689]

@@FrancisJohnYT Please by all means make it yours, use it, I'd simply be honored to see it shown off in your videos, knowing that I had the tiniest hand in helping create it. After all, I did 0 work in creating the boiler and merely found the fix by accident. Also I did not mention this in the previous comment but the 2kg of crude oil sitting in the tile did not impede the boilers output. I have been outputting 10kg/s of petroleum into a petroleum tank the entire time and have a small tank of crude nearby feeding it with 3 other pumps randomly through out my base near oil wells collecting all the oil to feed this boiler. I also think you could recreate this by placing a pipe output onto the square to the right and then once you start the boiler up, pipe in using a fluid control valve like 50 grams/s or even 5 grams/s and then just shut off the valve and let the rest trickle in until it's close to 2kg total. just a thought.

[@Garueri]

Coming back 3 years later to tell that if you play over 3x speed using mods its a great idea to give that filter timer a 40s config. Im running 30x (but in reality its 15x because I checked the clock and cycles take 40s not 20) and as einstein proposed, time and space are connected so if you go too fast your automation signals don't

[@avder42]

So I'm building one of these. The geothermal variety because my map only has metal volcanoes, no rock vomiting kind. So I look at my oil biome and think about where to put the heat spike and I find a spot in the abyssalite that gets me access to the magma lower than from anywhere else in the oil biome. So I throw down some ladders to get the dupes to dig down a few tiles as a head start for when I clean everything out and come back later. I may have dug one tile too far. I literally had no idea abyssalite could shatter under pressure from anything. I decided to take a look at my oil biome to see how the ongoing lead/fossil/diamond sweep is progressing and there's just this massive expanding cloud of purple. Like the steam at the end of your ocean vs magma video. I don't suppose you have a stupid simple design for a sour gas condenser that somehow doesn't require space materials and can kick out power at a rate higher than you're using it to condense the stuff? I suddenly have about half an oil biomes worth with all of those tiles pressurized to 15kg. Had to have the dupes go into yellow alert to get a column of tiles up to keep it from engulfing the other half of the biome where my slicksters live.

[@thomac]

It happened to me a lot with petroleum and with salt water. Either a very large body of fluids or a very compressed one will crack the tile eventually.

[@42agrajagg]

Had a similar problem, was digging out the stuff next to the abyssalite and it cooked the oil into sour gas. I was able to capture it and moved it to alot of storage tanks. I then built a double insulated room around an Anti Entropy Thermo-Nullifier with lead temp shift plates and started feeding it my Hydrogen from my SPOM. Quite a few cycles later, I was mostly empty room with a pool of liquid methane at the bottom and sulfur nuggets. Pumped the methane into another warm room and let it expand in natural gas and feed that to natural gas generators. I just kept this going until the sour gas is gone. The other option is to run a gas line straight up and dump it into space!

[@avder42]

@@42agrajagg Yeah since I lacked space materials I went with the AETN route for a while too. Eventually I augmented it with some thermo regulators running hydrogen. One difference in my design was I had a liquid pump next to the AETN connected to the room next door with two segments of ceramic insulated pipe. At one point that room had 70kg per tile of natural gas. And vent it to space? Literal waste of energy!

[@glennjanot8128]

I built a petroleum boiler like this but which has diamond tiles in lava with a steel mechanized door between them and a temp sensor set to 405°C. The weak point of this boiler is the pump. If the oil supply runs out or gets slowed, the pump will invariable overheat unless it's made out of Thermium. Had to built a door at the bottom of the boiler to access the pump. And thanks to the built, no petroleum comes out.

[@LWT1331]

Awesome vid as always. Sidenote: How do you manage to keep the CO2 from the petroleum generators at bay at 2:56? Was this before slicksters were nerfed and they would consume 1kg co2 per 4 sec? I'm having a huge issue where the pressure is about 17kg. Needless to say, my dupes can't go in there without atmosuits or their ears will pop. Since I built it too close to their living quarters (old save where I didn't know better) it's pretty painful to deal with.

[@FrancisJohnYT]

The slicksters are there for food only. I pipe the excess CO2 into space. You can also use door crushers to dispose of exess as well.

[@samuelgluss2751]

an additional note: it seems that the shape of the magma feed to the upper door of the magma dropper is important as well, I suffered from over-pressure there. In your design, it seems the magma must travel 10 tiles horizontally through a 1 tile gap to reach that door, I hadn't realized that was deliberate. It's unclear to me why you suffer from overpressure in the magma feeder otherwise.

My first attempt was a mess and I just restarted the game. Second time around I got it going but stuff started breaking after a few cycles because I did not put in enough buffers to account for stuff backing up in pipes. Third time around I put in all kinds of extra automation to control things before they got out of control. I still got sour gas forming for some reason. Fifth time things worked perfectly so I screwed up my base in another way: Sixth time around I had everything pre-planned and prepared and could not find a volcano on the map. :) The design is good but I have terrible luck with it :(

[@frantisekzverina473]

This design is just ridiculous. I'm even using the 140°C petroleum to steam polluted water into clean water. It only converts about 100g/s currently but I'm thinking of using the counterflow technique to preheat the polluted water and get a nice cold petro with nice hot clean water to pump into the oil wells. Dude you broke the game...

[@kevinjohn7056]

You could do the same for salt water as well, free desalinization. And if the steam is hot enough, you could capture that in a steam turbine to get a little more power and it cools the steam into water for you.

Store it. Huge area as tank, if not enough build inside tanks and fill them too. Otherwise turn boiler off by not letting oil in. No problems so far for me

[@FrancisJohnYT]

Have 5 petroleum gens and force them on when your storage tanks fill up, don't think of it as wasting power think of it and creating water and free CO2. You will have to be able to deal with all the Polluted water, CO2 and heat given off, but if you can do that you are set for the rest of the game.

[@Xkalnar]

Im having issues with the insulated tiles taking pressure damage on both side above the steel tile where the crude gets converted to petroluem, not sure why. But when this thing has even seemingly minor problems they get real bad fast....

[@Framba_GO]

I have the same problem, I noticed 2 reasons: where there are the 3 shift plates i put an insulated tile 2 blocks above the right steel plate. Once i removed it I had the second problem: some crude oil on the counterflow was blocking the flow. Idk why there was the crude oil there anyway

[@EllTee]

I had the same problem, even though the design for the conversion chamber was the same as the video.. Turns out that when I filled up the full chamber with crude (the four tile box and a little more into the neck) and it would start converting to petroleum I would quickly wind up with 3 smallish tiles of petroleum and a 800kg tile of crude pressed up against the right-side wall of the conversion chamber, which would overpressure and leak through the right side wall. The solution I found was to start with less crude in the conversion chamber - about 300kg per tile. That way when it started flashing to petroleum it wouldn't overpressurize the side wall. Once it all converts to a pool of petroleum then I start up the crude flow again and the new drops instantly flash when they contact the plate without making a tile and causing pressure damage. Then I started getting pressure damage in the feed pipes from the crude oil converting too early, but that's a different problem. I know this is an old comment on an old video, but I hope this helps someone. And thanks a ton @FrancisJohn for all the tutorials.

[@joelvisser4781]

I am new to ONI and I love your videos. I am having trouble deciding on how to get more power. Correct me if I am wrong but with 3 oil wells I can only get enough petroleum for 5 boilers. So that’s 10kw of power but I need more power yet. Is there another good way to get more crude oil so I can run another setup or is a petroleum based power system limited to my oil wells. In my case only 10kw of power?

[@FrancisJohnYT]

You are correct that you can only get 10KW with a petroleum boiler. It most bases that in enough power, are you recycling the power from your aquatuners? You feed the heat into a steam turbine and if you are using water you get effectively 40% of your power back. With super coolant you get 80% of your power back. Throw in some solar and some battery banks and usually you are good to run a massive base.

[@joelvisser4781]

Francis John I really love the quick reply especially, you’re very kind. I’m currently 1300 cycles deep (first world for me). I am recycling the power from my aquatuners though I’m only using water at the moment for my base cooling. I have only one aquatuner in running use as is. I’m perhaps over kill on a few of my systems such as oxygen production but I’m fairly certain I’m not wasting power. My waste comes from my smart batteries and that is minimal. I have yet to breach the surface and even get to rockets or solar. Which is why I worry as with some efficient automation I’m still about 8kw of continuously needed power.

[@FrancisJohnYT]

@@joelvisser4781 What is draining all that power? Did you build a lot of the recreational buildings? They are very power expensive for what they do which is why I tend to avoid them and get moral elsewhere.

[@joelvisser4781]

Francis John I actually take your advise on most of everything so my decor and moral are very cheap and very good I believe. None of my moral boosters require power minus the one gas range and grill I have. I have 4 lamps for my crops and 4 ceiling lights for the great hall but that hardly breaks the bank. I’m not sure where to see it in watts but I can see from the report that most days I use between 2000kj to 3000kj of power for liquid and gas pumps. By comparison my aquatuner takes 700kj average a day, for my base. I probably should just get more efficient with my pumps, meaning less of them but I feel I’ve done quite well. I was considering trying for the lumber to ethanol power system but I like your petroleum boiler so much more. I really appreciate the advise. You’ve made me even more of a fan and I’m grateful.

[@FrancisJohnYT]

@@joelvisser4781 Do you have your SPOM connected to your main grid? That would explain all the pump draw. I usually early on keep them on a separate grid where they are powered by the hydrogen they produce. They should pay for themselves but it will look like a scary power bill. If you have coal backup you should be find until you get your petroleum boiler online.

[@dpsilver1]

i was doing some testing on this Francis and from what im seeing the pipe that runs upwards in the heat exchange does not take part in any heat exchange so they may be made from regular piping to save on metals if you hover the mouse over the lower part just before the upright section and at the very top of the upright section the temperature is almost the same. at every other point in the heat exchanger there is almost a 10 degree C rise in temp for the oil i was doing some testing with 91C input oil to see if i can create a version that can be shut down and started up again

[@FrancisJohnYT]

Yeah their is no heat exchange in a vacuum and a negligible amount if gas is present. You can make them out of any material you want. I did not consider it worth the effort to mention, this is one of the more complex builds most players will do.

[@qzamboni]

Making this 2 years after video, I kept having a pocket of crude oil get stuck at the side under the petroleum and break through the insulated tile next to it when starting up. I managed to fix it by putting in another diamond tempshift plate, for an even 2x2 grid of tempshift plates in the boiling location.

[@FrancisJohnYT]

Their was an issue is some overpressure damage due the oil not converting fast enough when the magma temp got low. Crank up the temp sensor in the magma feeder by 1C and that should fix it.

[@TsieLeMoswang]

I am going to try to build this for the first time in the coming days. Wish me luck.

[@XaqNautilus]

II think it might be possible to get a minor volcano that produces less than 380 g/s due to how dormancy activity can pooch the calculation. I crunched the numbers on my minor volcano and it should produce 577 g/s but when it comes out of dormancy it doesn't just start erupting, this one wits 8 cycles to start erupting and also it can lose time on the end of the activity cycle as well when it will erupt and be "active" for 7 cycles and then go dormant. I didn't open the volcano and stockpile a bunch of magma and the boiler easily uses up all the magma and I keep having to rip the guts out of the thing to clean out the crude.

[@FrancisJohnYT]

I always wait on a stockpile or fill with a bit of geothermal to kick start it. The system is only efficient if it gets to run constantly, it's costs a lot of magma to start the system. So if you turn it off and on a lot it's going to be expensive.

Hi! Thanks for great tutorials and great content! It has sure helped me enjoy the game far more then I would have playing blind! I have tried to build my first petroleum boiler, but it wont work!

[@Smokeybear69420]

I'm interested in the different thermal conductivities of different fluids. If I were to use a thermal aquatuner made from Thermium, would using molten liquid lead be better than filling the chamber with hydrogen or steam? I figure liquid lead has a thermal conductivity of 11, which is better than the thermal conductivity of super coolant, and also is molten at the temperatures we need for a petrol boiler. Edit: Molten aluminum could even be used. its boiling temp is lower than the tuners overheat temperature, and has better thermal conductivity.

[@kurushimee]

Btw big thanks for your tutorial nuggets, I'm at cycle 1400 yet still feel like a complete noob xD (nope, definitely didn't delay making a petroleum boiler too much)

[@FrancisJohnYT]

The learning curve on ONI is a bit steep alright, the community has built up a whole lot of knowledge on builds over the years.

[@Nebulorum]

I just made my boiler on survival and I few questions: 1) After it went online, I noticed I had not have enough use for the petroleum and would run out of crude. I have to setup the oil wells to ensure the 10 kg. I tried several ways of stopping the boiler and always got bursted pipes and overheated pumps. Reducing the temperature of the boiling chamber resulted in unboiled crude and over pressure. I finally decided to run the petroleum back into the boiler and then reduce the temperature of boiling chamber. My idea was that keeping petroleum circulating would make it possible to slowly bleed heat out of the system. Is there a proper way of stopping the boiler? 2) I place the temp senso for the oil on top of the metal tiles. I still works. But do I need to have one tile gap between the temp sensor and the metal tiles? 3) What is the proper way to scale down the boiler if I don't have the 10 kg/sec of oil it demands? Anyway thanks for your awesome tutorial, love the mid game hump hints.

[@FrancisJohnYT]

Firstly if you place the temp sensor on the metal tiles the fresh dropping crude oil will occupy the tile it's in. This will cause the sensor to think it's colder than it really is so the sensor will inject more heat more often. I would imagine this would cause more heat to be injected, lower magma efficiency and increase the chances of bursting pipes. The best way to run the boiler is run it flat out or 9.5kg, setup three oil wells. Then ensure you burn off all your petroleum in generators as it's produced, sieve the polluted water output and put that water back into the oil wells and you can run the system forever. Keep a buffer of petroleum in case of outages. Turning the boiler on and off is tricky, the giant counter flow makes efficiency amazing but it is delicate. If you lower the input gradually by dropping the input by a kilo every cycle you can usually turn it of without issue but that is a lot of manually labor or lots of automation.

[@Nebulorum]

Francis John move the sensor , real easy because of the 2 tile high corridor and vacuum. I’ve had partial success with flowing the petroleum back in. I can lower the boiler temperature, but I need to cool the petroleum to maintain a gradient. However startup takes a while, since you have to reheat the chamber. It’s definitely finicky, one of the restarts resulted in too much crude in the wrong places. Will work to make it always on.

[@fuuryuuSKK]

Regarding the supercoolant + aquatuner setup, wouldn't it be ever so slightly better to run the cooling loop the opposite flow direction, to counterflow the pipe with that of the output petroleum? Just something I noticed when I watched you set up the boiler on Rime, because running the aquatuned loop the opposite direction means there's a bigger and more consistent temperature delta between the two

[@iakovzhitomirskiy1569]

If I just pump in Polluted water or salt water and turn the heat down to about 150 C, will this function as a water distiller?

[@bluefakederblauere2099]

[@oicronofobico]

This is an old video but I'll ask anyway. In my Terra map I have three oil reservoirs with oil wells and two minor volcanos. At first I thought about making two petroleum burners but, at the moment, I don know if the three oil reservoirs will be able to fully suply one of them. What's the math (or better, the design) to make this doable? Do I need a full 1k/s to make the petroleum boiler work?

[@FrancisJohnYT]

Each oil well produces 3.333kg/s of oil, so three oil wells gives you 10kg of crude per second. Each petroleum boiler can handle 10kg a second. You should only need one volcano, you can use the second to make geo thermal power if you want.

[@1x4x9]

Bringing my volcano boilers up has been an absolute nightmare. From burst tiles due to overpressure to the doors and magma not cycling properly, to even many overheated mining lasers I'm about ready to throw in the towel. I've referenced your save file and built everything accordingly but I just can't seem to get it to work right. :( Geothermal, while you're left at the mercy of the map seed for good magma placement, is definitely less fuss, less muss.

[@FrancisJohnYT]

Best advice I can give you in text, only put in enough crude at first to touch the temp sensor. Then stop inputting crude. Convert the crude in the tank and then turn it back on again. Crude oil stacks to about 840kg and petroleum only stacks to about 760kg. So if you have multiple tiles of crude in the boiler when you turn it on you end up with several tiles of over pressurized petroleum. This is what causes the pressure damage.

[@1x4x9]

@@FrancisJohnYT I know it's a bit late, but after going on a geothermal/thermium AT petrol boiler binge I started playing maps with volcanoes on them again just recently, and I've revisited your design - I was pumping in crude at 10kg/s like a moron, not letting it flash to petrol before adding more than 1 tile in height's worth. Plus I didn't add a liquid valve to control flow (or a shutoff too, as I put them in tandem with the valve to start/stop flow entirely just in case) volume. I have learned a bunch since I last posted my plea for help and it was a PEBCAK issue (lol) after all. You've played a huge part in making me as good at the game as I am now. I even have made my own 10kg sour gas boiler (it uses a hydrogen loop to cool the steam room by depositing it's heat in the natural gas about to be burned off instead of a secondary steam chamber and STs) and vertically oriented cool steam vent tamer, both work really well, and I wouldn't have been able to do it without the lessons I've learned over the last 2 years of watching you and others on KZbin.

The most efficient setups are not necessary what you want, it's usually better to aim for zero maintenance.

That should be fine, just prep the system with a couple of tile of crude then maybe start at 1 or 2 kg/s of crude until the counter flow starts to run.

So in my normal game, I noticed that there are magma layer directly below my oil. And If i destroy one tiles of the abyssalite.

And what should i do with the sour gas? I water lock the region. Sour gas wont climb to my base

[@FrancisJohnYT]

You can in theory do what you propose but if to much heat leaks through you will cook the entire oil biome. Also that means all the oil will be at least 500C. It generally gets out of control when you try it that way. I would dump the sour gas into space, you can in theory turn it into natural gas but it required super coolant from space to be able to do it.

As you put petroleum in it should fill the boiling area and then overflow down the stairs. If it's not moving the main culprits are either their is not enough oil or their is something blocking it.

This really didn’t work for me. On top of dumping 3 tiles of magma instead of 2, the heat exchange wasn’t fast enough and I got pressure damage which completely ruin my setup and forced me to have to restart my save-file. The temperature was staying at about 350C with 80C Oil being pumped into it and 1000C igneous rock dumping heat. Any reasons why it might not work?

[@FrancisJohnYT]

For three tiles of magma double check the length of the magma blade tongue, it it's to short you will get to much magma. Sounds like the oil was coming in a bit to fast and the magma was a bit to cold. Until the hot oil starts to counterflow you are not getting preheated oil. Try starting the system at 5kg/s of crude until the system is warmed up and hot oil is counterflowing all the way down the stairs, then ramp it back up to 10kg or 9.5kg which ever is your prefered.

Hello ! Thanks for this and this is crazy efficient for my base when I built it - but for some reason the one of the insulated tiles side wall between the vacuumed heat source and the petroleum keeps breaking due to over pressure? Am I dripping too fast? or sohuld this boiler be able to thandle 10kg at a time?

[@pokegaiyui]

Nevermind - I think I solved it - didn't realize I had to worry about Hardness of the material. I guess using Obsidian is the way to go?

[@FrancisJohnYT]

Ah this is tricky to explain, simply solution is to let out the spent magma a little bit earlier. Turn up the temp by about 2C. What is happening is as the magma is almost spent the crude stops converting to petroluem. Then the fresh magma drops in and all the crude converts all at once. Crude stacks to roughly 820kg a tile, petroleum stacks to roughly 740kg. So when the crude converts to petroleum all at once you suddenly have a tile of over pressurized petroleum in the boiler and the walls get damaged. If you cycle out the magma a little earlier the crude should not accumulate to do that any more.

[@348joey]

I guess this has been updated since then, because copper radiant pipes only have a thermal conductivity of 120. Steel is 108, iron 110, and lead 70. They're all listed as "High Thermal Conductivity". How much do you need to change for those values?

Hey Francis, I have a minor volcano right on the border of my map, so I extend the magma droping area to make room for the heat exchange section below, would this work? I am so anxious..

[@FrancisJohnYT]

All you need is a magma tank and a dipper the correct length coming off it. So long as you hit those two boxes you should be fine. But to be safe maybe make a few backup saves for peace of mind. I made a lot of mistakes before I got my first petroleum boiler working, also several more after I got it working :)

4000 cycles is longer than most people will play this game...I'm on my first playthrough, cycle 2500...still don't have solar and can't get geothermal up and running with steam...oops. Guess it's time to start a new base.

[@JacoWeijts]

I'm using a minor volcano. I have the feeling the magma cools too much while sitting in the tank, causing it to become solid. Should I have the entire thing vaccuum?

[@FrancisJohnYT]

Yes, always use a vacuum when working with magma. It's incredibly dangerous stuff so always use a vacuum.

No. Dump it in liquid ethanol, oil, plastic, polluted ice, and phosphorite. You will not regret these decisions I swear.

Hey dude, I've been using your petroleum boiler design for a few years now across multiple different saves. It is fantastic, but I find it randomly leaks (liquid from the petroleum area leaks through the insulated tile, lands on the rock and fills the chamber with natural gas. It can run fine for like 800 cycles and then just randomly leaks for apparently no reason. Have you come across this? I'm wondering if it is something to do with game lag...?

[@FrancisJohnYT]

I know this problem, it's to do with the temprature setting for ejecting the spent magma. In the video I have the temp set to 435C but I edited the description to indicate that you should change the temp to 440C to avoid pressure damage. What is happening is that when the temp of the magma gets near 335C the crude oil in the boiler stops changing to petroleum and builds up. Then when the new magma is injected the fresh heat causes all the collected crude to change all at once. Crude can have 870kg per tile, petroleum can have only 740kg, so in rare circumstance you can end up with overpressure petroleum at the right moment to cause a bit of pressure damage to the tile directly to the left of where the crude oil is dropping. Personally I never had the problem but I always used Obsidian on anything touching magma, Obsidian is supposed to be tougher than Igneous Rock. Perhaps that is why it never showed up in my testing. Change the temp setting to 440C for ejecting spent magma and the problem should go away. Also in future maybe use Obsidian insulated tiles for the boiler area to be extra sure.
