Technology comparison of CFB versus pulverized-fuel firing

Feb 22, 2009 · 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.
