I've just built a 36hp biofuel-powered boiler, powering 18 industrial steam engines. The boiler is now above 100*C, and is outputting steam. However, the GUi on each engine says they are only producing about 1.8 MJ/t each. Thats a far cry from the 8 Mj/t i'm supposed to be getting. I thought the boiler was supposed to max output as soon as it reached 100*C. What am I doing wrong?
