Metal from metal volcano not cool enough

[abissus]

I am using 2 steam turbines with each metal volcano (gold and copper), with about 113kg of steam. The metal in the middle of the volcano only gets to 500C. Watching video and other help I thought it is supposed to get down to 125C? What am I doing wrong?

Debris lying on the floor exchanges heat fairly slowly so you should probably build some conveyor rail loop which magically speeds up the heat exchange.

Adding 200kg of crude oil or petrol into the steam chamber will do a lot to help move the heat from the metal to the steam.

Would the crude oil go to sour gas since the metal is coming out at 2600C? Or if I add crude now to metal sitting at 500-600C would that change to sour gas?

How long after the volcanoes go idle are you waiting? It takes a while to cool off depending how much material needs cooling. Things should eventually equalize at 125C. You could also add an aquatuner and actively cool the area (or move the materials and cool them somewhere else) at the cost of power, some of which you can recoup with the steam turbines.

I have not seen that happen, does not mean it wont happen.

I use a very generic system for taming the metal volcano's as well.

The volcano room has crude on floor, then water placed over that. Access to the volcano room is crude oil liquid lock then vacuum then another crude oil lock.
The heat escapes through a Steam Turbine placed up top.

The debris is cleared quickly after construction. The metals deposited by the volcano are left to sit in the chamber until needed and the whole thing can only be accessed by suit.
Suits are the only way to leave my base so that does matter since I do not expect dupes to be able to grab hot debris while without a suit on.

Most storage bins on my map are set to "sweep only" so its very unlikely that any hot debris is brought into the base unless it is going to be turned into something which means the temp of constructed objects is ~40C.

Crude Oil sitting in the metal volcano room wont flash off cause its transfering heat into the steam/water pretty fast actually.

Now this system mentioned above is actually energy positive, but not by enough to matter much. It does not require any energy from the grid.

Now if you want to quickly cool down debris,

You need aquatuner, steam turbine, and a rail system.
This dumps heat into the steam bath that is deleted by steam turbine.
You can actually attach this to an existing system like the one I outlined above if you like.

Further cooling of debris below the ~125 range will cost energy cause you need to run an aquatuner and rail system.

If you happen to dump 1kg worth of crude oil into the chamber, yes, it can convert into petroleum or even boil into sour gas.

However, a full bottle of oil has enough mass that it will be fine-- you ought to end up with ~50 kg/tile or so, and steam temperatures ranging from barely over 125C for a gold volcano, to 150C for a copper volcano, to nearly 200C for an iron volcano.

Update. I put about 15kg (per tile) of petro in and put 1 diamond tempshift plate behind the hot metal. Now they are down to about 200C. I tried more plate and that didn't seem to make much difference
I can try putting more petro and see if it helps
Thanks for all your help.

Pictures would be great, especially with the rail system.

Final update. Cycles later they all reach equilibrium. Gold is at about 140C and copper a little above 200C, metal and steam are the same temperature. That's as good as passive cooling is going to get I think.
Unless I add a third steam turbine to the copper volcano I guess

Keep in mind there's a "reset temperature" when you use the materials to build with. 40C I believe, I can't remember the exact number, wiki or someone else can verify. I'd leave the materials where they are until you use them, you'll delete a bunch of heat this way. Then maybe actively cool what you've built if you need to, at least you're only cooling from 40C rather than 140C+.
