Volcano boiling oil for power

[Moggles]

I had an unlucky roll on gas geysers so I went for an alternative in my current play through.

Nothing really new here but I see a lot of debug oil boiler builds and this one I made in survival without debug tools.

The boiling chamber I keep at 20kg per per tile. The upper holding chamber is kept at around 6kg. The cooling chamber no more than 1000g per tile.

It's been my primary source of power for a few hundred cycles now. Posting mostly for inspiration and I'm quite proud of how it turned out. I was on a clock to establish a vacuum in and around the unit while the volcano was dormant.

Cool. I'm not sure what your boiling capacity is, but using the incoming oil to help cool the gas could speed that process up (in theory) as well as make the heat of the volcano last longer, theoretically allowing it to sustainably boil oil at a faster rate.

@Luminite2 My oil valve is only set to 200g/s. I'm hesitant to turn it up higher because I forgot to add a hydro sensor in the boiling chamber to detect flooding. I was actually toying with sort of the opposite idea of preheating the oil as coolant in a metal refinery to save magma heat. Right now it's at 55C which could as you say help with the cooling.

Another option I thought of was to use the 600-700C gas to boil polluted water. Would get clean water and cooling at the same time.

You could use the hot Nat gas to heat steam to use it in a steam generator or a couple of. I know the steam gen is not really great but it deletes heat very well and some extra power isn't so bad. 

This way you can get the 700°C gas down to about 300°C quite fast and efficient. Afterwards use the 300°C to preheat the oil that's much saver than preheating with the 700°C gas. 

Cheers!

I assume that the magma around the volcano will eventually freeze and you have no solution for cleaning up the magma chamber. Or does magma freeze as debris in this case?

it harden's solid but tends to melt again, the whole volcano is more likely to flood out than freeze out when in a vacuum

with the heat pulled from beneath like this

Yeah but the volcano is overpressurized or isn't it? That means you are drawing energy constantly w/o adding any heat to it.

[Moggles]

The heat of the magma has dropped from over 1700 to over 1500 since the volcano over pressurized in that state.

I will continue to use the heat of the igneous rock until it's unusable I guess.

I think I can clean it out when it solidifies. I have the vacuum area underneath. If I am still playing by that time I will send a dupe up from the bottom to the left of the boiling plates to dig out the chamber.
