Help on my steam turbine design on a volcano

[Elin64]

Hello,

I have a seed with poor natural gaz income and 3 minor volcanos so i had to use a good steam turbine design to get electrical power.

 

Here is my design:

I have 2 problems:

- the heat transfer is not really effective, as you can see on the right there is vaccum + tempshift and the temperature doesn't seem to transfer well to the metal tile which is at 230°C. Should i had hydrogen in the room, will it help to transfer heat from the rock to the tempshift?

- the design in the room with the mechanized air doors doesn't work at 100% even when the steam temperature is very high.

This is not a big issue but can i get a better result? and, more importantly, when the steam turbine has its bar colored in red (not generating electric power), does it use some of the heat of the steam?

Using volcanos for the steam turbine has some problems.
How do you get your material out of the chamber, when it's solid?
A robot miner and autosweeper in that room could help with that, but you have to cool them, without cooling the room ^^
Forget steam turbines, they suck a lot, in combination with volcanos even more.
They are for deleting heat in the moment, nothing else (survival).

You don't really need anything else than a robominer if the heat extracted is limited to less Kdtu's than what the volcano can provide as new magma from the volcano will just remelt the solidified igneous rock but each time a tile is dug half the mass is lost which will ensure that new magma is generated to keep a balance.

you can add metal tile behind volcano and automatized door to control temp leech like this maybe

Perfect and every dormancy, you could rebuild it very easy.

Vacuum is a pretty good insulator, so if I am being honest, I am surprised that any heat at all is making it to the boiler chamber.

The magma rolls off of the lip onto the floor.

There are several volcano builds on the forums (though most are archived - so hard to find). You can find them in the spoilers of this post.

When you get your build finished, and are happy with it, message me and I'll add it to this list.

I have a really big pile of 300 degree regolith setting next to a bunch of ice for a lot of cycles that says that debris transfer heat poorly, if at all.

Debris don't transfer heat except to fluids, afaik.

So in OP's build, how is the heat getting into the boiler at all? The only point of contact is a vacuum.

... because, as I said earlier, the magma falls off of the neutronium every time the volcano erupts.

So there is a brief window between the magna rolling off and becoming debris,  and that is the only time any heat makes it? Guess that explains why the chamber is hot at all.

Magma only becomes debris when it cools, which only happens when it heats the chamber.

Not 100% accurate, discovered by accident that debris will transfer heat to the tile beneath it and the temp shift plate behind it. However it is much much slower than the transfer between liquids, solids and gas. I was able to squeeze out enough heat for my petroleum boiler but I doubt it would be enough to be useful with a steam turbine.

solids only interact with tiles underneath then, you can also put some liquid at the robo-miner.

As for OP's build: it would be more effective if you would control how much heat is being transferred to the steam. Right now you are transferring as much heat as possible as soon as possible to the steam. So you waste heat potential due to the fact that the turbine outputs a static temperature. 

 

Great way to delete heat, terrible way to generate power.

Tempshifts do not interact with debris, but they do interact with the fluid on, and solid tiles below, the debris... and both interact with debris.

(Walls are insulation. Non debris started at 20C.)

Ah so what I was seeing was the tile below the debris absorbing heat and then the temp shift plate was absorbing heat from the tile itself. So use very conductive tiles and temp shift plates if you want to get he most heat out our your debris.

Above magma, as soon as the hydro sensor doesnt detect any liquids it pushes down the igneous rock to the hydrogen chamber without "infecting" the room above. The door right next to the switch serves as dupe entrance for sweeping the debri. It should be possible if im not mistaking. I dont have any clue about the automation

i think it works. turbine chamber stabilizes around 260degree. could be optimized further. 
- changed hydrogen with liquid (super cooland obv. best)
