I just notice that you have two recipes for the conversion of 1500deg into 500deg lead, one making 1k of 500deg steam and the other 1k of 1000deg steam. I don't know if you are aware but higher temperature steam in a vanilla turbine does not consume less steam. Indeed, the extra 500 deg of energy above the maximum temperature is simply wasted...(This used to not be the case prior to 0.15)
1000(500-15)200 = 97 MJ => Vanilla Turbine (16 + 2/3) => 97 MW / 50 (1500 deg Lead ) = 1.94 MW / 1500 deg Lead
1000(1000-15)200 = 197 MJ => Vanilla Turbine (16 + 2/3) => Temp cap => 97 MW / 100 (1500 deg Lead) = 0.97 MW / 1500 deg Lead
1000(1000-15)200 = 197 MJ => Vanilla Turbine (16 + 2/3) => Without Temp cap or higher temperature turbine => 197 MW / 100 (1500 deg Lead) = 1.97 MW / 1500 deg Lead
Indeed, the second formula, while attempting to provide a better heat conversion is simply worse than the first
Is this intentional? If not, could you provide a higher temperature turbine or an expansion valve to expand 1000 deg steam into 500 deg steam?
