You had my curiosity, now you have my attention! This would be quite interesting indeed to check.

@rufus the steam turbines seem to be about flow through them. I refined the design a little (not sure how many pumps I really need) but a second boiler helps keep the flow rate through the steam turbine at 3600L/s a single turbine was making 11000 power

Nice! I will try reproducing this after work today and if successful, will implement the changes on the version in my submarine.

@Rufus, I'm making some progress on turbines by putting a large pump on the steam inlet of each turbine and not sure if necessary but a pump on the steam inlet to the condenser. I currently have 2 steam turbines making 3300 power and climbing. I have like 6 medium water tanks on the water inlet with no pump. That seems to be working fine so far but I'm sure I can use less water tanks.

Pistons are utterly broken even after the fourth hotfix according to feedback on the Discord. Though I remember a comment saying that pipes now spawn filled with air, so this might indeed be an issue to consider later. I will keep you posted if I get a working design.

I've tried a different setup with pistons. It seems like the boilers take longer to heat and require a higher reactor temperature.

The reactor needs to be purged of pressure before you start it. My example reactor spawns in with 155atm of pressure in gas. The high reactor pressure will stop a large fluid pump from being able to move water back into the reactor from the boiler if the pressure is over 100atm.

I don't know if it's air in the system but it helped using the new fluid relief valve and port in the reactor. Fluid tanks in front of large pumps going in/out of the boiler seem to help with flow. I also had to add some fluid tanks to add more water to the system, like you said the boiler depletes the water.

The power, at least from pistons, isn't there. I'm going to try with steam turbines and see what I can do. Those seem to be about how much steam you can flow through them so hopefully that will work a lot better.

Agreed. I tinkered around anyway, and here are my findings, FYI: the main issue is very much boiler-side, when the temperature goes above 100°C, water boils correctly but as pressure gets above ~ 2,2, the steam output seems to saturate in some way and the water level in the boiler quickly collapses. Pressure increases from that moment as water boils inside faster than it can evacuate but the water cannot go in as fast as before until there's no more water in the system. As the water lowers, the temperature of the boiler does as well until it goes below 100°C. I tried putting a large fluid port right after the boiler and an overcharged impeller pump, but the steam output doesn't change.

@Rufus, I would just wait for the devs to figure out how they're going to fix the game. nuclear reactors were creating steam from the fresh water. Today, it doesn't seem like it. I'm going to wait for a couple more hotfixes to drop before I really start trying to fix stuff. Who knows what changes they'll incorporate to get the game back to where it was.

Working on it as the fluid update came and the hotfix unmessed it. At the moment, the boiler has issues, but I believe it can be worked by putting an impeller pump in front of it to push water forward and a PID to control the pump's motor and keep the pressure around 8.

Welp, if you have any idea how to fix the reactor after the fluid update, I'd be so grateful.

Thank you for the response.

Gav the fix is pretty easy. Use logic to limit the reactor/boiler pumps.
You can uses these microcontrollers and adjust the settings for your set up.

Thanks for the fix. Was it a hard fix or could i quickly fix the one in my sub without to much work.

Thanks a lot for this fix! I'm correcting my submarine with it.
