Fluidized bed combustion Wikipedia

Fluidized bed combustion is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials through which jets of air are blown to provide the oxygen required for combustion or gasification. The resultant fast and intimate mixing of gas and solids promotes rapid heat transfer and chemical reactions within

What is the difference between a PC boiler and a CFB boiler?

·

Jan 19, 2015· Pulverised coal is often conveyed to the burners in boiler through pneumatic means (by forcing coal particles by using moving air) from the coal pulveriser mill. Some issues with the PC boiler: 1. Coal is combusted at temperatures of about 1600-1800 deg C. At such high temperatures, NOx, which is a notorious pollutant, is formed.
