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

Coal Quantity Since coal has a heat value of 20,000 kJ/kg, for producing one 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

Coal mill pulverizer in thermal power plants
