Easy-to-Make GEOTHERMAL PETROLEUM BOILER | Oxygen Not Included "Spaced Out" DLC | Tutorial/Guide

[@K-o-R]

Incorporating a giant heat exchanger to pre-heat the input and cool the output is wonderfully elegant.

[@05AquariusNova]

Not only you have shown a simple design but also demonstrated how to build it from nothing. I love your guides! Thank you!!!

[@tejing2001]

A great introduction to the petroleum boiler in its simplest form. Also, good coverage of the things to be careful of when building one. Working with magma isn't really that hard, it just takes patience and forethought because a single mistake is deadly, plus it's helpful to know a few oddities of ONI's physics simulation. If I had been making this, I probably would have made it 3 levels high, so there's room to replace the heat spike with a thermium aquatuner + tepidizer later on when (eventually) the heat from the magma biome runs out. Of course, the other solution is to run it off a volcano, but that gets into more difficult magma handling issues, so it was probably for the best to avoid that here. You kind of skimmed over the advantages of the oil well -> petroleum boiler -> petroleum generator -> water sieve -> oil well loop, so I'll cover it in a bit more detail here: Because of the efficiency increase a petroleum boiler gets over an oil refinery, this loop actually consumes NOTHING AT ALL (except filtration medium for the sieve, which used to be free due to regolith, but in the dlc is a bit more of a concern. You can always replace the sieve with a polluted water boiler if you're not sure you can sustain the filtration medium), so when you're using it, it actually makes sense to waste its outputs, just so you don't slow down the production of other outputs. This is a bit counterintuitive when some people first try it. They instinctively feel like petroleum is a valuable resource and try to automate their generators to only run when batteries are low, etc. Don't. The first priority is that the loop always runs. It's correct to waste the outputs in order to maintain that. Done correctly, this loop can be the basis for 100% sustainable power and oxygen, leaving food as the only thing still to be managed to keep your base going forever.

[@mood3995]

Just curious, at what cycle does geo-thermal energy run out? I heard it will last for thousands of cycles. Considering that I won’t be playing for that long, is that a concern?

[@tejing2001]

@@mood3995 It depends immensely how thermally efficient your petroleum boiler is, but thousands of cycles is certainly realistic. I tend to prefer to run it off of a volcano just so that I never have to think about it again, but yes, a reasonably efficient geothermal one is likely to last long enough that you don't care.

[@PaddyTheGamerPop]

"leaving food as the only thing still to be managed to keep your base going forever" --> You can feed the large amounts of CO2 coming off of the generators to slicksters for meat/barbeque (who also give more crude oil!). Depending on the scale of your operation, this may be enough food for forever.

[@tejing2001]

@@PaddyTheGamerPop Slicksters aren't really a viable food source on their own, though it is a nice bonus. The amount of CO2 (and space) you need to raise enough slicksters to feed a dupe is just prohibitive for any significant number of dupes.

[@PaddyTheGamerPop]

@@tejing2001 They have the same life cycle and produce the same amount of meat/eggs as hatches. They are literally as viable if not more viable a food source, as with the right setups, CO2 is easier to provide than minerals. You can set up the ranches below the CO2 producers like your Petroleum and Coal generators, easy peasy! =)

[@michaelrichards5340]

Man this was a really good introduction to this system you're an amazing teacher, clear and sharp

[@ilikestarcraft]

This is my favorite petroleum boiler. I’ve experienced every possible way where things could go wrong, and learned from every mistake. The amount of crude oil going into the boiler is very important. I’ve found out 5kg is the best. Less than that, the petroleum doesnt cool down enough(the frustration of finding sour gas after a couple dozens of cycle…gosh..)and more than that sometimes make the doors stay closed for a tiny bit more(which can cause rapid raise in temperature and you could end up with sour gas…again..) Anyway thanks for the greatest setup! This lets me have infinite power in my base without using any manpower. Oh by the way, I dont cool down my crude oil and the default temperature is usually 80 something celsius. If you use cooler crude oil, I guess you can use less than the 5kg flow, as in this video.

[@chumprock]

Was was the final temp of your output petrol, and did you try doing anything to cool it further??

[@josiahhockenberry9846]

I had to watch this video several times along with a few others just to understand how it all worked. I took my time and the study paid off cause I was able to get it to work without any problems on the first try. It's been running stable for several days and now I got all the petroleum I could ever want. Thank you so much!🙂

[@ИгорьДементьев-и7м]

there's a way to make heat exchanger MUCH smaller.

[@realityextractor1956]

Still the best and most clear tutorial on petroleum boilers out there. Thanks!

[@shousper_]

TFW you find a video and watch it for the first time on the exact day it was made 2 years later.. I thought setting up the Kovarex process in Factorio was delicate, but this sounds downright scary, lol.

[@padreigh]

Nice - another real ONI tutorial. No sandbox mode, real dupes doing their best to sabotage the build :o) lots of newer buildings have something similar to get the warmth from the air in the house out of it to prewarm fresh air taken into the house before expelling the "used" air - essentially its a kind of heat pump. nomrally though you do not use the transfer medium directly but have it as closed loop and transfer heat by some heating liquid.

[@chumprock]

Thank you so much for this video (two years later) that *finally* got me through my energy squeeze and hopefully push into more distant planets! I struggled with temp balance for a while (petrol was coming out wayyyy too hot and climbing) and seems like for my 71c crude 5kg input worked the best. I also had a chunk of iron sitting right on the temp shift plate at my petrol pump and not sure if that was contributing heat, but get all that debris out of there! Now how do you manage it when you are reaching the storage limits for your petrol? Do you just keep building more tanks and pray, or is there a sane solution to brining it offline?

[@TheMalT75]

Nice and detailed video, thanks! An important improvement: With a little extra automation, you should check the crude oil temperature at the "kink" shortly before being dumped in the "reaction chamber". An AND gate that links your petroleum and crude oil temperatures to the steel air lock to keep it closed if the crude oil reaches 402°C. For very long duration, you also want do use a double layer of isolation between the conversion chamber and the heat exchanger (to the right of the steel door sandwich). This goes in the same direction as the comments by @Jeff Huffman and stems from the difference in thermal capacity between petroleum and crude oil. It is not that much, but since conversion takes 10kg of oil at 403°C and changes it to 10kg of petroleum at 403°C, a petroleum boiler actually generates ~70DTU heat per kg oil converted. You can exploit this mechanic more substantially by melting regolith and generate the same mass of igneous rock! Here this means, crude oil temperature will keep rising in the pipes along your heat exchanger over time. Certainly not a problem for 1000+ cycles because your setup has a lot of thermal mass and is not vacuum-isolated from your base, but I had built mine more compact, in thermal isolation and running very long, so of course I ended up with damaged pipes... To put it differently: You use crude oil at 30°C to cool petroleum at 403°C. Since petroleum has greater "thermal mass" (mass times specific heat capacity), the high temperature creeps towards your cooling input. But with the extra temp sensor, your magma lasts even longer as you effectively use the "cheated" heat to power the conversion ;-)

[@bpdlr]

"An AND gate that links your petroleum and crude oil temperatures to the steel air lock to keep it closed if the crude oil reaches 402°C." Don't you mean "keep it open"? - i.e. so as to cut off the heat?

[@TheMalT75]

@@bpdlr You are probably right, and the AND gate would then be wrong, too. Open airlock means no more heat and is achieved with a green signal, so you would just need to connect both sensors to the door and set to "green signal if temp higher than"... but I have not played in a longer while and am too lazy to check now 😇

[@Renegade-Master-88]

The simplest boiler ive seen so far, much easier than playing with volcanoes

[@arcanixz9575]

Thank you for the part where you show us how to build it in game, lots of other guides don't do that

[@jugghayd]

I tried this one but it melted all my radiant pipes and Automation wires and sensors. EDIT: Oops, I didn't realize lead had a relatively low melting point.

[@AdamRotering]

I have only done one other boiler before. This one was mush easier to follow. Thak you

[@HyperionGamingTOPKEK]

Regenerative heat exchanger? Dope.

[@peterschabig9566]

Works great and I only accidentally generated 22 gas reservoirs of sour gas in the making 👍 Magma digging was a lot easier than I thought too, wouldnt say that a single mistake is deadly as others have written, I made tons of mistakes lol, literally had to use some airflow tiles right on top of the magma to get out the sour gas.

[@TheMindverse]

Do yourselves a favor, and build this! it's simple, maintenance-free, and productive. BUT, make sure you look at the gas overlay frequently. Dupes may get called to lunch or bathroom, and drop whatever they're carrying, including 1600 C Abyssmalite or Obsidian. If they do that when passing through the petrol liquid-lock, you'll have a massive sour gas problem. Just be careful.

[@jensolsson9666]

Make it possible to turn off: raise the openning of the petrolium "well" one tile compared to the heat exchanger, the heat transfer between the boiler and the heat exchanger is broken when the oil input is turned of. prevent over cooking: place a temp sensor to the right of the metal tile at the top of the boiler, you can fine tune the temperature of the top metal tile so it does not over cook. The tile needs to be placed in gas then isolated around.

[@malarkey7242]

This is excellent. Well done

[@audrianmarak1574]

I do not really like to place tempshift plates near insulated tiles, they soak up too much heat and make systems slow to start if you have lots of tempshifts, petroleum boilers are fun, takes 5-10 cycles to set up and lasts forever (till the heat dies) :D

[@latenight6815]

And breaks everything if it's idle for a while because heat climbs up and breaks the pipes eventually

[@vgalimbertti]

Great video! Question: any particular reason for the tiles directly above and below the steel door not to be diamond window as well?

[@sertawhalat1633]

bro i really liked your channel.hopefully you will get more subscriber

[@Dani0x1B]

Apart from the power and the water, you can also get meat out of the boiler by using the CO₂ to feed slicksters

[@Nilaus]

Somehow my slicksters always kill themselves. I need to dedicate sone time to get some good designs going

[@brianhauptman]

@@Nilaus I've taking to having a radiant pipe petro filled liquid loop going through my slickster holding pens, with an end of the loop going through an automation controlled heat exchanging brick. 120 is a good number to target to slowly convert to molten. If the holding pens are small but open at the top, they never seem to get cramped. I just insulate the parts that are not behind the slicksters or in the heater.

[@Dankz_Live]

This is perfect. Thank you!

[@dunning-kruger551]

Love to see your berry sludge production line. Bristleberry meh, but Sleetwheet farm?

[@lammaerb7867]

Any effective way to cool down the hot petroleum somehow? The thermal aquatuner + steam turbine cooling is wastly inadequate, the petroleum generators overheat eventually getting the hot petroleum....

[@TheMindverse]

WARNING: Great build, but there's a pretty big flaw in the construction aspect. Those rocks we're constantly sweeping at high priority? The ones around 1600 C? Well, the petroleum in the liquid lock flashes to sour gas at 540 C. You do the math. It took me forever to figure out where all the sour gas was coming from and spoiling my vacuum.

[@Nilaus]

Warning: Comment above doesn't know what he is talking about! I've run this for 100 hours and never seen any Sour Gas. There is nothing in contact with the petroleum that is close to those temperatures

[@TheMindverse]

You didn't read my post. It wasn't the operation, it was the construction. Digging out Abyssalite (and Obsidian) right next to magma, yields debris 1000 degrees and up. Carrying it through petroleum has resulted in several sour gas bursts - during *construction*, remember. Even as we speak, I have a temporary Storage Bin *inside* the build filled with 900 degree obsidian among other things, and am figuring out how to get it out before start-up. I'll post a video.

[@Kotsknots]

@@Nilaus savage

[@CatalepticHunter]

Late comment, but for future readers: Minerals that spawn in magma will indeed start life at about 900 C. Players need to be very careful about where they put this particular leftover material when digging around magma. In particular don't just dump it in with your general storage, as it will leak heat, and you may not realize what's cooking your base. It will definitely also flash oil to sour gas, so definitely don't dump it in or near oil. Usually, I just let it stay in the magma, since it's basically hazardous waste. However, dupes can transfer it without difficultly, so it can be rendered safe by dumping it inside a steam turbine's boiler and bleeding the heat off as energy.

[@dead_heart_man]

1000 iq man awesome blueprint

[@timtimtimmaah]

Why do you need the space for the vacuum? Wouldn't it be enough just to build the tunnels one square high so the petroleum pushes out any gas?

[@alienbricks3823]

thanks work nicely

[@thefactorymustgrowlarger3947]

Beginner question here, what is the motivation behind the diamond window tiles? What would happen if you simply dug up the lava?

[@strawb6476]

Diamond window tiles are really thermally conductive and they carry heat from magma to the boiling area. You could put the boiling area directly above the lava, it'd just be awkward in terms of layout

[@Nilaus]

Diamond is an amazing heat conductor and it can withstand extreme temperatures. If you let the lava flow in the dupes will burn and you need to manage a liquid instead of the solid tiles, which is much harder (how would you pump molten lava if you have excess)

[@LarissaAraujo-ph2mv]

I think I'm missing something about the temperature of the crude oil input. My pipe keeps bursting near the liquid vent

[@igatmatthew2283]

just make the last few segments of piping near the vent out of insulated igneous or obsidian pipes.

[@carlossouzaamorim]

Uma outra solução é passar o tubo por dentro dos blocos antes da saída. Eu sempre uso uma válvula de controle antes de liberar o óleo ativando com um controle de nível pois a densidade do petróleo é diferente e fica possivel parar completamente o boiler quando detectar a densidade do óleo.

[@AkshayAradhya]

Idk why you used 2 rows of metal tiles when you could have used window tiles all the way through

[@MGerdtell]

Any tile that directly touches the magma should be made out of obsidian, just to make sure it is not going to melt on you.

[@Nilaus]

Or diamond or steel

[@MGerdtell]

@@Nilaus Yes. In that case, I was referring to your insulated tiles near the diamond windows. They are made out of Mafic and MIGHT melt if you let this run long enough.

[@tyraelpl]

23:34 well... you dont rly xD you can just with diamond all the way to the door, no steel needed there ;)

[@Ichibugin19]

do you have a petroleum generator setup? can i see it?

[@mrdewes]

At which cicle do you guys get to magma? I tend to take a lot of time before going down

[@ИгорьДементьев-и7м]

About 50 cycle

[@Bear-88]

Best guide ive seen

[@bpdlr]

Couldn't you use a cheaper alternative like tungsten/wolframite for the metal tiles/mech. door? Melting point over 3k.

[@Nilaus]

Not every map has abundant wolframite. Steel is always available and not really hard to get by the time you build this. But other materials can be used as well

[@enkiduo]

Great video, very solid boiler, I haven't tried one with an internal vacuum, seems like a good call for reliability. These things are a huge pain to get started - really glad you went into that in detail. I need to experiment with diamond windows for heat transfer - seems like overkill at first glance - you dont really much heat transfer if you have a proper heat exchanger setup as you do - I woulda just dug down to the lava, setup a gas exit, closed off the area and then pumped some hydrogen or ethanol in there - im lazy though.

[@blubbber]

similar design can also be used if you want to use a vulcano. Francis John has there a nice tutorial for watch?v=YddtS8ZKbIE , add a colling loop then for the igneous rock and you have unlimited supply of it .

[@Nilaus]

Using a magma vulcano is way more complicated. This is supposed to be a starter build.

[@Ibian666]

My only issue is the diagonal digging. I try to avoid that, especially with big important things. Kind of a matter of pride.
