How much steam should you have per tile for best effect on the Steam Turbine? Is it 1kg per tile under it? Is there a problem with having too much other than it takes longer to heat?

I'm not sure what the minimum is, but there is no maximum pressure. Efficiency is only limited by temperature of incoming steam and number of open ports. I think that's in the wiki.

each turbine port sucks in up to 0.4kg/sec of steam. which means the steam in the chamber get disproportionate and the equalizing of gas mas battles that removal of 0.4kg/sec. I think anything over 10kg/tile can be considered safe if the return pipes are not extremely long.

That's what I hoped you'd say. I tend to put a good amount of water in. I was just afraid that long startup times could cause excessive heat to get lost.

I generally prefer to err on the side of too much steam than too little. To little steam and the generator won't run optimally due to lack of pressure.
Too much steam just means that you need to put more heat into the thermal mass under the turbine before it starts to run optimally.

The latter simply means, that you need to put more heat into the room initially before it's able to run full throttle. The former means it won't run at full throttle no matter how much heat you have.

Less water also mean you are likely to get hotter steam, but steam that also cools faster.  For a simple cooling setup, that isn't really an issue, but for harvesting volcanos, it can become one.

I was overboiling some water for rockets and was surprised to find out that the liquid vent will overpressurize with 1000k of gas pressure too.  So perhaps gas pressure can break tiles it just has to be more gas pressure than anyone could normally get to.

You have no heater in that steam room! You must be a warlock! D:

There is a very shy aquatuner cowering behind the tooltips.

Also you can do the same thing as with gas vents with the liquid vents to allow more pressure in the room by putting it in a low pressure tile of hydrogen to avoid over pressure.

I just woke up. Gonna chalk this one up to that.

That aquatuner needs to get out and socialize a bit more.. I know, the world is a scary place, but...

My usual steam chamber contains 200-250kg of steam per tile.

[Most of the time I just fill the chamber 1 tile high with water.]

Most people build steam turbines because they want to lose heat.

A high steam pressure increases the amount of leaked heat.

As Lilalaunekuh said, generally a total of 1000kg of water does the trick, stable enough yet not too much SHC in there and easier to build, simply fill a tile.

Nope. There are infinite gas storage builds and do not need multi-tile walls.

I don't think I've ever had any of my 'infinite gas storage' rooms reach a pressure over 1000kg/tile.  Most of mine are usually 200 to 500kg when I start using the resource I've been saving up.

Do you mean 1000kg per tile or 1000kg per steam turbine? That's a single tile of water.

If you were going to do more than 1000kg of steam, there are ways to get around this. The only reason I can think of to add an enormousness amount of steam would be to have it act a battery bank with a stable power supply. You could even automate it to include a shutoff that adds more water as it heats up.

It's actually the liquid vent that gets damaged due to "overpressure". Something about liquid + gas pressure interactions, perhaps?

I broke my liquid vent this way back in a QoL III colony, I assume it's the same in LU.

Edit: Actually, I double checked. It was the pipe itself, as the water unable to escape was heated and converted to steam. So don't mind me.

The liquid vent does not take damage from being over pressure. Liquid vents simply have a max pressure of 1000kg. That's why it stops when it fills up with water, and it doesn't when it fills up with petroleum. It doesn't care if it's gas or liquid. Same for 2kg gas vent and 20kg high pressure vent.

If you are building your steam room surrounding a volcano, you can over pressurize your volcano and it will stop. I keep them at 120kg per tile for this reason. Apparently they are supposed to overpressurize at 500kg.

That's not the point, the most important is to have enough steam to don't burn the AT. Even with steel, if you don't have enough steam (> 10-20Kg / tile), it will burn because the steam have a really small thermal conductivity so you have to offset that by a mass effect.

But you also have to don't put too much steam if you don't want block the liquid vent.

Yet I didn't use an aqua tuner and I got it working ;)
