My current experiments did show that per 10 coalĦ3 iron or is smelted in the stone furnaceġ25 iron ore is smelted in the steel furnaceĦ2 iron ore is smelted in the electric furnace(probably a small loss to heating up some water in the pipes.Īt the moment the coal run out at the electric furnaceĦ2 were produced at electric furnace. Steel Furnace has a higher product output and a lower coal consumption. There was a nice webpage to provide you with the data but it is been currently hacked by jimmy wales who has replaced all content by his face.īut back to the more important steel production: It's a lot about heat integration (use heat exchangers to cool down outflow and heat up inflow without external heat). On real world furnaces the kg Coal per kg ore (efficiency) and kg metal/kg ore (productivity) and kg/s metal per m² area(speed) have all been improved in the past significantly. One level 1 efficiency module for the electric furnace will reduce all the pollution with 30% giving 4,61*0.7=3,27, so 1 efficiency module is enough for the electric furnace to be less polluting than the steel furnace. They have the same production speed, so with 100% steam generated electricity the steel furnaces generated less pollution then the electric ones. Pollution total steel furnace per KW - 0,0226/KW.Pollution coal mining is half of electric furnace since the steel furnace is 100% efficient Pollution steel furnace per KW- 0,02/KW.Pollution Total Electric furnace per KW- 0,0256/KW.Pollution Electric furnace per KW - 0,005/KW.Pollution mining total per output KW boiler - 0,0052/KW.

Pollution mining electricity per output KW boiler- 0,000693/KW.Pollution mining per output KW boiler- 0,0045/KW.Some pollution calculations (all pollution is per tic)Įdit: However as lxl said the coal needed for the boiler also gives pollution. I have used 100% steam based electricity generation for the calculation. I thought it was interesting to calculate the pollution of the Electric furnace and Steel furnace and see which one creates more pollution.
