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.
