circulating fluidized bed boiler smoke ventilation system

Zhengzhou Boiler Co., Ltd. was founded in 1945, 70 years history has made the leading boiler manufacturer and exporter in China. This article is mainly about circulating fluidized bed steam boiler smoke ventilation system.
Balanced ventilation CFB steam boiler furnace pressure zero set in the furnace exit. Circulation of materials within the circulating fluidized bed by the blower (including one or two fans), the Roots blower and induced draft fan to maintain. From a fan out of the air by an air preheater heated air into the furnace at the bottom of the primary air chamber, wind through the cloth hood panel of the bed material flow and the formation of solid circulation upward through the furnace; secondary air by the second Air preheater heated air to the furnace side of the argument, from the bottom of the furnace wall into the furnace before and after the combustion chamber; the second road on both sides of the secondary air duct from the boiler leads to an air duct to the blast furnace, and then trail leads from the wind 3 coal drop pipe branch pipe to the wind as the broadcast of coal. Carry out the furnace flue gas of solid particles, through import of flue cyclone, respectively, into the two tangential cyclones. In the separator, coarse particles separated from the flue gas, and gas flow through the tube into the flow splitter center shaft, flue gas cooling by convection heating surface, through the tube into the air preheater flue gas dust removal Composition of fine particles, and finally, by the suction fan into the chimney, and into the atmosphere.
