Comparison of Circulating Fluidized Bed Boiler and

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 CFB uses higher pressure primary air which is 60 % of the combustion air for fluidizing
