After considering the conversion efficiency in a power plant we require an heat input of (3600 / 33.44% ) 10765 kJ/ kw hr. 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.

The primary air flow is dependent on the load on the power plant. If the load is high then the primary air pressure will also be higher. The rate of raw coal input is also dependent on the load on the power plant. If the load is high, the primary air flow will increase and then to keep the preset air/fuel ratio the raw coal flow will also increase.
