What are the main components of circulating fluidized bed boiler?
1. Primary air fan: after being heated by the air pre-heater, primary air enters into the wind chamber, then into the furnace through wind caps through the air distributor to fluidize particulate materials;
2. Secondary air fan: after being heated by the air pre-heater, secondary air enters into the furnace through the secondary air ducts for complete combustion of fuels; the seal air, conveying air and fuel spreading air of the feeding device also adopt secondary air;
3. Circulating material returning air fan: the function of circulating material returning air is to help unburnt fuels enter into the furnace again.
