Calculation of fuel consumption in boilers

Feb 22, 2009 · PC firing utilises coal ground to a very fine powder sprayed into the furnace for combustion. CFB uses coal crushed to sizes of around 3 to 6 mm. The time energy and facility required to crush coal is much lesser than pulverizing coal. PC firing uses around 30 % of the combustion air as high pressure primary air for drying and transporting fuel.

Difference Between AFBC Boiler and CFBC Boiler, AFBC

AFBC is atmospheric fluidized bed combustion, where the furnace pressure is atmospheric pressure.The flue gas from the furnace goes through a cyclone and is let out to the atmosphere. As for CFBC, circulating fluidized bed combustion, the furnace is pressurized and the furnace gas is recirculated to capture the unburnt carbon, to increase the thermal efficiency of the boiler.

Circulating fluidized bed - Wikipedia

The circulating fluidized bed (CFB) is a type of Fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion. while achieving lower emission of pollutants.Reports suggest that up to 95% of pollutants can be absorbed before being emitted into the atmosphere. The technology is limited in scale however, due to its extensive use of limestone, and the fact
