![]() When I did this exercise for 0.16 the numbers were way, way worse. Total efficiency is ~285% with all of that power being usable since you aren't starving the output. Nearest whole values for a coal fueled steam system: 21 units of coal gets you 15 bricks of fuel. Total efficiency is: ~285% (720 / 252) though only 708 of those MJ are usable elsewhere in the factory bringing the effective efficiency down to ~280%. Total power: 240MJ in, 720MJ out, 12MJ recycled. Also, you forgot about the power cost of 50 units of steam which is 1/8th of a brick of solid fuel or half a unit of coal (one unit of steam is 30KJ or 0.03MJ, it takes 50 units of steam or 1.5MJ to run a coal liquefaction cycle, which is 1.5/12 = 0.125 units of solid fuel or 1.5/3 = 0.5 units of coal).įinding the nearest whole values for a solid fuel steam system: 80 units of coal gets you 60 bricks of fuel (7.5 solid fuel*8 cycles), 59 of which go out to the world and one is recycled back into the system. The nice thing about 65H is that it ratios perfectly to 5 solid fuel per cycle. Also thanks to /u/FeedbackControl for pointing out the energy cost of the production buildings.Ĭoal Liquefaction should output 90H, 20L, 10P, or 65H net. So total energy output is about 82.62, or just over 2 times the energy of the coal input, very worth it.ĮDIT 2: Thanks to /u/cathexis08 for pointing the net H output and steam production requirements, he got different values output values though so I'm still not confident my above calcs are accurate. Turning 10 petroleum into solid fuel requires. Turning 68.75 light oil into solid fuel requires ~2.89 MW Total SF output: 8.27 (~99.2MJ) 7.375 SF (88.5 MJ)Įnergy requirements of running the buildings is 5.88 MW: Liquid output (minus heavy oil input): 75H 65H, 20L, 10P Steam input: 0.125 SF is needed to create 50 units (1.5 MJ) of steam How much energy in solid fuel do you get out for the coal going in?ĮDIT: I did the math but I'm not confident so heres my working:
