Thank you very much. Please switch the coolant to either water or polluted water.

that not helps if steam is 500c

Ive always used petroleum, mostly due to the low temperature that water boils at and cracks the pipes.

This kind of cooling loop is for your steam turbines. Which have to be below 100ºC to operate. Pipes would crack because of other points of failure.

There are some assumptions being made here:

• The insulated tile that is being used directly below the turbines is at least ceramic. If not available, then I'd choose igneous rock in an emergency (then switch to ceramic ASAP.) Pretty much the same applies for insulated piping in hot environments, but I'd make them ceramic from the get-go.
• Insulated piping inside insulated tile is safe. (within reason)
• The turbines are not kept at any kind of high temperature to buffer for emergencies. So the ambient temperature for the steam turbines can be 30ºC, for example. The AT will take care of that.

Please don't leave your AT unattended, ever. It's worse than giving kids coffee:

The coolant is being used to help the steam turbines stay cool. Not the hot steam vent.

In the screenshot above any insulated pipe that comes into contact with steam has to be at least ceramic to prevent heat from the steam chamber from going into the pipes. If you're crafty with bridges then you can "skip" some risk areas.

I would also check the temperatures from the insulated doors mod.

The AT will not help too much if using petroleum. Even salt water will do better if in need.

The higher the SHC the better.  This makes the choice of what you pump into the AT itself a pretty easy list when cooling steam turbines.

but you say self in other thread that you stay away high temp setups, are you even try cool down 500c setup with Aquatuners?

500c input is over 300k heat what makes it 3 turbines in default temp

4 x 3 = 12 turbines, you can cool down 12 turbines with one Aquatuner?

The best way to make it clear is that I don't like blocking the steam turbine's vents.

OP's build should be actually cooling off the steam from the vent before it gets to the central turbines. Some problems here and there, but I believe in it.

[Orzelek]

If wiki tables are correct then if you consume 500 degree steam thats about 340kDTU/s of heat emited per turbine. It drops to 260kDTU/s at 400 degree steam. You have one aquatuner there which with water/pwater can cool 585kDTU/s. With petroleum that you have it goes down to 246kDTU/s.
Without inlet blocking when geyser explodes you get a heat burst that can't be cooled down quickly enough by aquatuner. You get 2.6kg/s of steam when vent is running. Since numbers above on turbines are at 2kg/s then you need about 1.3 turbine to consume it (not accounting for steam pressure etc). For that time in theory that 1.3 turbine will output about 440kDTU/s.
So aquatuner with petroleum is overwhelmed during the venting and temperature of whole system will go up. If you switch it to water and provide some cooling mass on turbines (plop lots of water onto floor and pre-cool whole thing to 10-20 degrees) it should hold easily with 2 turbines (and lots of power wastage - steam above 200 with unblocked inlets wastes energy since turbine is capped at 850W output and thats reached with 200 steam).

[gabberworld]

when you close 3 vents at 500c then turbine temp will be 140kDTU/s and it still continue produce the 850w but with less water output

[JRup]

@Orzelek

Those are good numbers for a setup where we would have to process the whole 500ºC with only 2 steam turbines. Petroleum just won't help too much. But the steam turbines at the sides of the build will.

There is no need to vacuum the surroundings of the steam vent leaving some steam as a temperature buffer can help. The center turbines can be toggled with an atmo-sensor.

I don't know the exact value, but yes, the steam turbine will still produce more heat even with blocked vents. The only thing that is "rescued" by blocking vents is the amount of power produced.

A couple of thermo sensors (light green arrows) to operate the airlocks (dark green arrows) and keep the turbines processing safely below 200ºC and the build could come to life (195ºC is nice). (A steel power transformer can be easily popped in next to the aquatuner to power the airlocks with a wire...)

thing is that 360c is needed for 3 vents closed , then it act same like 200c

then its below the 100 kDTU/s

[Orzelek]

Closing inlets actuall reduces heat output since turbine will process less water per second then = less heat deleted.
Will trying to disable turbines help in this case?

All turbines are in same room so when two central ones heat it up then side ones will get heated up too and stop working anyways. Rightmost one has some chances since it gets fresh coolant.

And that small bridge is very well spotted
It will heat up turbine room quite nicely in addition to turbines and provide constant heating.

thats how my reactor works, somewhere 95% water goes back to reactor and 5% is waste, for stabilize temp, i have 2 extra turbines what cools room down if it goes too hot

and its been running over 100 cycle without nonstop

that is not only bridge he have there also pipe bridge what also little transfers heat unless if its insulated

Correct!

I'm not used to seeing the long bridge, but here it is:

Liquid/gas bridges will still conduct even if made of insulation so the material they're made of only helps in not having much of an effect if conducting towards a tile.

Luckily for OP this can be fixed by moving the long bridge one tile to the left, for example. That way the bridge will be inside the insulated doors.

well it docent matter because i not use mods, if geyser produces 110c im not sure how he can run turbines, if steam is over 200 same thing starts happen room heats up much faster that aquatuner cant cool it down unless if stabilize by closing vents

Completely irrelevant in this context. Those quotes and replies were about the joint plates and nothing else

When you say that joint plates conduct and I say that these joint plates don't, then of course it matters

[ATM Reaper]

Ok so same subject but different build.

Should I have gas in the steam turbine room or is the petroleum layer enough to cool?

 

Someone pls help as I am about to have a melt down (pardon the pun)........

as you control your temp with doors i not see issue in your setup

Petroleum is enough but you still put bridges everywhere

Won't these leak temperature from the steam room to the steam turbines?

[DolphinWing]

I'm not sure if it will flow correctly?

Also, I don't think you need that many tempshift plates.

Personally I don't use that complicated design. Maybe because I don't need that much power.

Yes is the simple answer, I litterally just figured this out myself and it has fixed the issue. In progress of testing if it resolves my earlier issue also.

Don't forget to correct the automation bridge that is in the first build you provided.

Yeh thanks man, Ive got rid of most of the automation it was mainly to give me control of the generators, now I dont need that as the issue is resolved. Just waiting for it to become active again so I can verify it is stable.

[ATM Reaper]

Ok so final post on this, both my builds are now working, thanks for all your help folks. Every day is a school day in Oni I guess......

[helium3]

Was the problem the bridges? I noticed yesterday that one of my steam chambers was leaking a fair bit of heat through the insulated tile via a bridge. I had to swap the bridge to the horizontal line to stop the leak.

I’ve never really noticed this before and I feel like I’ve played enough oni that I would have noticed this earlier. I’m wondering if there’s been a recent change to liquid bridges. I even tried changing the material to ceramic and it still warmed up quite rapidly. It just didn’t transfer heat into the gas above quite as fast.

all bridges transfers the heat and its not something new

[helium3]

Yeah. I’m aware that bridges transfer heat. I’m just having a hard time believing that I’ve never before noticed liquid bridges heating up to the temperature inside the steam chamber and then transferring that heat out into the surrounding gas.

*shrug*

One time, like an idiot, I put a heavy watt joint plate through the side of a steam chamber. I noticed THAT right away and this was similar.

[ATM Reaper]

Yeh sadly the bridges were the problem, I only had one in the steam on my steam generator build and it killed it so defo something to avoid doing. Both are working an absolute treat now though so happy chappy.

I hate that this mod https://steamcommunity.com/sharedfiles/filedetails/?id=1938747693 is not in base game already.

I hate that you have to have liquid for heat exchange and not just some contact plate.
