Buker capacity is generally designed for 12-14 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.

The MPS coal grinding mill with a high drying capacity is very suitable for grinding lignites with feed moistures of as much as 45 per cent. Depending on this high feed moisture, the mill rating is determined by drying whereas for anthracite, hard coal and petcoke the rating of the mill is determined by grinding. The great
