How to Calculate the Coal Quantity Used in a Power Plant ...

2009-10-15  Coal Quantity. Since coal has a heat value of 20,000 kJ/kg, for producing one kw.hr we require (10765 / 20000) 0.538 kg of coal. This translates to (0.538 x 100 x 1,000) 53800 kg/hr (53.8 T/hr) of coal for an output of 100 MW. Coal Cost. Basic cost of coal depends on the market conditions.
