Closed coal bunkers emerged as a novel form of coal storage for coalfired power stations. Nevertheless, heat builds continually in the storage process because of the constant oxidation of coal and combined with the impact of a confined coal bunker environment, it is difficult for heat to dissipate, resulting in frequent coal bunker fires. Consequently, research on coal pile combustion ...

Calculation of coal handling plant and bunker capacity

Calculation of coal handling plant and bunker capacity

Buker capacity is generally designed for 1214 hours of full load operation. Let us calculate with 12 hours of operation hours. Coal consumption in 12 hours = 392 X 12 /24 =196 MT. Volume of bunker = 196 X 1000/800 = 245 M3. Take 10% of extra margin on bunker as some of coal stucked on bunker wall surface cannot be used for Boiler.
