Steam engines stop and start with low temperature warning, despite 150C steam

If you're using self cooling on steam turbines, try lowering your steam intake temperature to 135C, for higher temperatures you need to provide external cooling.

Note that the testing branch has changes to how temperature is calculated. See this post for details.

 

Wow, thank you for the detailed responses! Going to read through the Steam Turbine wiki entry so I don't make the same mistakes
