Ep16 Old school Petroleum boiler : Oxygen not included

[@ddopson]

Francis, I did a fair bit of research on improving petroleum boiler reliability, and found that replacing the temp sensor with a liquid element sensor (detecting oil vs petro) is a simpler, more intuitive, equally efficient, and safer control scheme. In addition to controlling the heat-injection, this can be used for an auto-shutoff mechanism. First, whenever the oil hasn't flashed to petro for 10 seconds, shut off the oil injection faucet. Second, put a pipe element sensor on the oil input line, and whenever there's a hiccup in the oil supply (or any other error conditions), block all heat input by holding the injection door open. For example, don't allow heat injection to resume until there's been at least 30 continuous seconds of oil detected in the input pipe. Withdrawing heat causes the oil to stop flashing to petro, which closes the oil injection faucet, safely shutting down the entire boiler. Critically, it shuts down in a state where all oil / petro in the boiler is below the oil-to-petro flash point, preventing any sort of pipe breakage. This system also limits the maximum oil backlog in the boiler -- allowing too much unconverted oil to build up, due to some form of heat interruption, and then flash all at once when heat injection is restored, this can lead to transient pressure spikes that break the insulated tiles causing oil to escape the boiler, contact the magma, and flash to sour gas, creating an EPA superfund site. Some of my other innovations related to reliability of the magma dropper, which your design here omits. Point is, I stress tested this design for 100's of cycles, fed it an inconsistent oil source that would pause randomly, interrupted electrical power, etc, and nothing I could do to it would break the boiler or the pipes within. And I was using maximally efficient aluminum pipes that brought the oil all the way to 400 degrees before it dropped, achieving near perfect efficiency -- mine being the volcano / magma-drop based variant, I added thermal mass to prior to the heat injection door to better stabilize the heat injection, making it safer to have gold interface tiles between the door and the oil, although there's an argument for diamond tiles being less efficient (they cause more temp overshoot) but more foolproof (if you screw up and melt the gold tiles, its catestrophic). I did tests with gold / diamond and powered / unpowered to measure heat overshoot, and can look up those numbers if you'd like.

32:00, on counterflow heat exchange: biological, too. The bloodflow in polar bear paws works like this - blood vessels going to the paw (full of warm blood, from the thorax) are intertwined with the ones going back to the heart (full of cold blood, from the paw touching the snow), so they exchange heat. So overall the bear needs to waste less energy to heat its own blood.

The only really noteworthy change in the realm of Petroleum Boilers is using Escher Waterfalls for maximum heat exchange efficiency. But this is a "casual playthrough" :D

[@JoelleTheAbsurdist]

Counterflow heat exchangers are most commonly used in rooftop(sometimes the unit is in the basement with a coolant line going to outside. More expensive to build, much cheaper maintenance) chillers. Water or glycol flows over the evaporator coils, cooling the water, it's pumped throughout the office building, cools the place down. It is far more efficient then using forced air throughout the building. The same line can then be used to heat the place... but is usually not, and a separate hot water circulation is piped along side the chill line. I don't know why... super low fuel prices for 30 year making the industry complacent?

[@CompproB237]

The details on the meteor shower are the "scan". Seeing the makeup and when it's going to hit are part of that. When you don't have a telescope watching the skies you just see the meteor with no details. Side note: It seems the meteor showers come at about the same time. I haven't paid much attention to it but it _always_ comes a little after the start of a cycle on my game.

[@bobsprock]

I think there's a timing on the wiki as to when they come. It cycles through the different types every few cycles with downtime between, iirc.

[@gradious7497]

Endgame challenge suggestion: Hot Food Challenge After the early game, when duplicants tend to eat food that's hot off the electric grill, the colony's food supply tends to be rather chill. Almost every meal a duplicant eats from midgame onwards will be at either refrigerated or deep frozen temperatures. If you were forced to eat frozen burgers straight from the freezer without reheating, day after day after day; wouldn't you feel the urge to destroy things, or to vomit, or do some ugly crying? Don't the dupes deserve some hot food for a change? No, not 40C or scaldingly hot, or boiling hot, or steaming hot, or scorching hot, or molten lava hot. The dupes deserve to be fed meals hotter than a geotuned niobium volcano-hot! Challenge: Feed a majority of the duplicants of the colony on food that is hotter than the eruption temperature of a geotuned niobium volcano for 10 cycles. Difficulties: The food will not be deep frozen due to temperature and will slowly expire. Realistically, this shouldn't happen at these temperatures because the food should have turned into a block of refined carbon. Also realistically, eating 1Kg of 3000C+ food should transfer enough heat to fully cook a 60Kg duplicant from the inside. I think it would be funny to see extreme duplicant heat deletion. Even more so if the dupe is wearing a warm sweater while eating food HOTTER THAN MAGMA. Heating the food to that high of a temperature will be tricky. Obviously, the first step is to preheat the food into the niobium volcano's output. Then, heating just a little more finishes off the buns to the perfect temperature. The storage and transportation of hot food should be interesting. Will you build a base for the dupes on the niobium planet? Or can you fire it back to the home planetoid? Can you manage food that is too hot for thermium shipping rails? Do you put a payload opener close to the mess hall to take advantage of the payload capsule sealing off the food from temperature exchange? Will a vacuum storage over an insulated insulation tile keep heat inside? Is the food so good that the great hall needs to have a dedicated aquatuner above every 2 seats? Or is the food so good that dupes have to put on atmo suits to eat it inside a vacuumed out great hall? Dramatic ending & colony send off: sweep millions of calories of niobium melting-temperature food to the top of the base and let it melt its way through to the bottom of the base.

Edit: posted the first comment before the second half of the video, thermometers use to only measure up to 200 I believe so it was hard to automate the heat injection unless you got creative and use phosphorus boiling point to automate your door closing but it wasn't perfect. So we use to just eat the efficiency lost and used flow control to make sure stuff didn't over heat. That was pre steel days.

I think the best update to a petroleum boiler I've seen is the staircase design where you pump petroleum up through the exchanger to avoid damage to the pipes. It has a more awkward shape though, but in theory it can work better. Also, I wonder how long until you'll start overclocking the magma volcanos and turning them into rock gas spewing monsters :D.

[@samir5740]

[@pedrolmlkzk]

You could use them as abyssalite flakers

[@matthewbauerle7153]

Don’t you need thermium to do that? He doesn’t have it yet.

[@TheMule71]

Hi Francis! The exchanger works better if you build an insulated tile one down and one to the right from the liquid vent. The way it is now, the heat source is trying to heat everything up including the first stage of the exchanger, it's all thermally connected, heat can travel all the way. If you break that connection, your first stage is going to do its job better. That's also what makes the pipes right before the vent break. Of course you need to move the vent one tile up. With such a large amount of magma, efficiency matters not. But the pipes breaking is annoying. You still need be careful with starting it up, but with the top stage not connected to the boiling chamber, it's much less finicky.

[@TeracomConsulting]

so you're saying to add a 1 tile wall that the petrol has to flow over to get into the exchanger? Would Makes sense. But if it is flowing over, do you still not have a thermal connection?

[@salemprompthous3820]

@@TeracomConsulting yes, to adding the overflow-tile. With a vacuum in the area, there'll be no connection to what's on top of that tile, and the liquid pouring over to the heat-exchanger. Different issue if there are any gases, which is why it works best in a vacuum, or no place for gases to exist (the entire build set for one tile to have petrolium flowing)

@@TeracomConsulting personally, I'd say Volcano if it's your first, just to get a personal feel for it. Ofc, if volcano is available.

Building a boiler with Niobium/Thermium is quick and easy, which is why I'd recommend to try the not-so-easy first. With some time and possible scaldings, can always replace it with an AT setup if it doesn't work 😊

You can greatly improve the boilers ability to not break pipes if you separate the heating chamber from the heat exchanger. (Preferably with a 1-tile waterfall) This prevents all the pipes from bursting cause they wont be able to get to those temps Added benefit: boiler gets better heat efficiency

[@alexvsergeev]

Also, the oil vent should be placed (submerged) on the bottom of the boiling chamber, not above it. It’s an extra protection in case heat runs out for any reason.

[@brandongeertson7346]

@Alexander Sergeev I disagree. In case of shutdown, you have one blob of oil near boiling that can't get out, slowly heating up...leaving you with another burst pipe... Personally I like to use a temp sensor connected to the vent above the flash chamber. No chance of breaking, right?

For the industrial sauna and hooking up your oil wells, use all that salt water you got there. Pipe all that saltwater into the industrial sauna, then set up the output of a couple of those steam turbines to feed the oil wells. If the oil wells don't need as much water as you're pulling out, dump it into a reservoir for O2 or into space. Also, if you can manage it, maybe flood the map with petroleum as a casual end game goal? You already flooded the map with water, let's see if you can do it with petroleum or something else.

[@agsystems8220]

Speaking of molten diamond, can I suggest a late game build that is worthy of you? The diamond remelter. Diamond actually melts at a lower temperature than refined carbon, and has a far lower specific heat capacity. If you melt diamond and then recondense it as refined carbon you produce a huge amount of heat, at temperatures high enough for an abysalite melter. You can use a refinery to maintain the temperate peak, but you can also use the fact that you can have solid refined carbon at high enough temperatures to melt diamond, coupled with the drip solidification bug/mechanic. If you drip 1kg/s of liquid carbon at

[@TheMalT75]

Wow, what a cool idea. Similarly crazy as the salt gas to liquid salt exploit of different specific heat capacities... Without the 1kg/s solidification bug, is the cycle: 30°C diamond -> 3930°C liquid carbon -> 3549°C refined carbon (solid) -> 30°C refined carbon -> 30°C diamond ? That would need heat per gram of -2000 +270 +6123 = 4400 DTU/g/s. Or about 4000W from steam turbines per kg of diamond melted, nice! And not quite as easy and overpowered as regolith melting...

[@agsystems8220]

@@TheMalT75 Yes, though there are no natural 'topping' heat sources, so you would need to use refineries. The cool thing about the drip bug, and what makes this unique to carbon, is that you have a liquid you can produce using lower temperatures than the melting point of the thing it solidifies into. You can use the drip bug to keep the hot end at that temperature indefinitely. It is similar to a regolith melter, but they still need something like a volcano or refinery to keep the hot end hot. This does not. You can exploit the solidification bug to get lots of power in simpler ways, but they all require some way of getting the solid back into a liquid, which requires some source of heat that is hotter, so at best it will be an amplifier. This is the only one I am aware of that does not. The power is interesting, but what I really like is that it is an infinite sustainable supply of liquid carbon, and you can use that for anything. You almost certainly need a nuclear reactor already working to get the radbolts anyway. It is definitely an exploit, but is so hard to actually make work that I am absolutely ok with this being something I use, including double dipping on the heat of the liquid carbon. Before solidifying it (setting it's temp to ~4200) you can pull it down to 130 and get another 2kw out of it. If it didn't need the radbolts I might be a little more suspect, but they make it feel a lot less exploity, and more mechanicy. Frankly the numbers work out so well and it being so hard that I wonder if it was deliberate!

You can still tunnel through magma with the horizontal doors method, you just have to be *verrrry* careful about how long dupes are allowed to build down there. I usually set up 3 manual switches at the top along with automation wires connected to the doors in sequence, just extending the automation wires to continue the sequence (so that each switch controls each 1st, 2nd, or 3rd door, if that makes sense). Lets me control access to the building area. It's definitely slower than it used to be but absolutely still do-able.

I did some testing in debug mode to make sure, but the reason your petroleum boiler took so long to hit operating temp is that tempshift plates right next to any tiles will dump heat into them.

Should not matter for heat transfer as long as the 3x3 area of tempshift plates overlapp and touching tempshift plates increase thermal mass by a lot.

While the general design for petroleum boilers is *about* the same, the heat exchanger specifically has go through some evolution. Also you're not supposed to let the petroleum in the boiling pool have a direct path to touch the petroleum in the heat exchanger, this causes even *more* pipe breakages.

[@Majromax]

Regarding the plan to have the end state of the colony be one of leisure, with no duplicates performing work, I don't think that by itself will be very entertaining. Since steelmaking, planetoid mining, and construction all require labour, you'd be restricted in some of the megaprojects that might be worthy of such a colony (e.g. no steel-based meteor melter). However, you could go with the Futurama Method : have all of the physical labour performed by a single Australian dupe.

Put one up in the space biome and you got yourself an easy to use fuel source for your rockets until you can transfer some bees over and set up uranium drilling in space ( and set up a nuclear reactor + infinite storage for nuclear waste as source of rads ) Awesome though how you tamed that magma biome I'm just too much of a chicken to dig into those.

And it takes your FPS with it.

That ? on the comet is a visual bug. If the tooltip tells you want kind of meteors there are and the time to collision, it's technically scanned. It should've updated to show a slimy meteor icon.

[@lonelyPorterCH]

Another rocket exploit lol, I love it^^ Also, dupes beeing dupes, falling into lava/magma, sleeping on top of lava/magma. Even better^^

[@jacob6885]

Could you use water pressure to bust the windows? Airflow tile on 3 sides, small infinite storage... just pop the windows out?

[@VyktorAbyss]

late night ONI.... oh you dirty drinking all day in the sun boy!

[@ziptiebandit]

@FrancisJohnYT if no one's suggested it yet, we should absolutely end this play through dumping a vat of liquid depleted uranium on a base. You probably should move the dupes out first. Probably.

[@jasonmoggridge1566]

I melted the rocket windows by dripping molten tungsten on them through ceramic pipes after melting all the steel. I was a lot easier than I was expecting. I probably lost ~2T of tungsten to space.

[@thebosstre]

2:20 no wayyyy No idea u could do that

[@takatiny]

Francis I thought you were going to put a petroleum boiler inside a ticket and feed the rocket with the the output.

[@Pawel_215]

i think that aluminum is bad for petrolelum boiler, at very least top part of it. It requires so much of maintanence (other thing might be that i only run it at 2/3 of capacity

[@nico-ob6wj]

I'm really surprised that the metal refinery does not overheat in the vacuum

[@jaredlaws9875]

Not that you need it but,you could geotune that volcano and it would produce more magma at a hotter temp.

[@NatanStarke]

Even rock gas if for some reason wanted

[@michaelsotomayor5001]

Don't put the window tile right there 30:20 for the love of god :D it will burn the pipe unless you put a bridge to overlap the tile it's fine

[@hquest]

Just another very casual play, I see.

[@RiffZifnab]

In my experiments longer heat exchangers don't actually help with efficiency, more of them do. I talk about this in my sour gas boiler design doc: docs.google.com/presentation/d/1Mi8QYacLwqQUwSsM0sE5ooIiGOlWIgXB8cpGrfc0z18/edit#slide=id.g1446b553040_0_0 I never did put together my bead pump petroleum boiler doc, but it was similar.

[@pet3rgaming]

You would love to use the deconstruction mod... it's perfect

[@haibach7054]

Love the videos. Thank you.

[@KimpaTheCool]

magestic video!

[@ripmorld9909]

Francis you can totally go with a nuclear engine , you just need to build a shinebug reactor

[@TheMalT75]

Or a rocket silo! It is enough to get a mini rocket into orbit once to generate enough fallout for "sustainable" radbolt generation...

[@arkadarkartist]

any good mods or tips to prevent performance issues?

[@samir5740]

Just commenting so if someone finds something i get notified. getting around 14fps endgame here.

[@bearus126]

performance always kills my games before really getting into late game. it's so annoying

[@agrro_krysia3244]

Francis, everything ok? It's unusual time for your video :P

[@vulmar1]

I wonder if you could get a petrolium boiler into one of the rockets and have it fuel itself somehow

[@derekoyama501]

Maybe a small one with slicksters I'm not sure how you'd be able to it so that the oil boiling part and the part that generates carbon dioxide for the slicksters are kept separate probably just a liquid pump and some tiles to separate them. I think of the options for sustainable generation of carbon dioxide i think it comes down to either polymer presses which don't give off that much carbon dioxide but also don't require that much petroleum or a petroleum generator which takes 2kilos of petroleum but outputs a ton more carbon dioxide. don't think slicksters really work that well when there is a ton of things being processed tho.

[@vulmar1]

@@derekoyama501 are there any other rocket engines that can be fueled by a closed loop?

[@derekoyama501]

@@vulmar1 I think you could in theory be water positive and run steam back to their own engines as long as you have like places to stop. I dunno how long you might be offline waiting for enough steam to actually fly.

[@vulmar1]

@@derekoyama501 was trying to think of a way to stay flying.

[@TheTdw2000]

Perhaps for the pre-heating you could use molten glass? It's got a temperature lower than that of the melting point of steel but it'll definitely get you past the threshold for the primary method of heating.

[@xjun91]

Francis is there a reason why you make the metal tile above the door in your petroleum boiler out of gold instead of let's say diamond window tile?

[@vulkandrache1928]

I havent been keeping up with this game at all. Why do the insulated tiles look so weird?

[@bloodchain80]

can you build a rocket, inside the rocket?
