China Structure Characteristics of CFB Boiler

CFB boiler of our company adopts single steam drum and natural circle, membrane water wall. Its firebox, separator and fly ash return material system are laid into incorporate and the structure is compact; The return material system adopts high efficiency cyclone separator, J valve back material device, fuel echoplex uniformity and glidingly; Grind-proof design of the boiler is safe and reliable; Distributing air system adopts water-cooling air style, ignition below the bed, air nozzle being laid cannily, so that distributing air is symmetrical and steady fluidized quality. Having air fuel adaptability, the fuel may adopt anthracite, lean coal, soft coal, also can use some bad fuels that can't burn for other boiler, for example: Gangue, chain bar slag, making gas slag; Adopting the fuel of higher containing sulfur, by adding limestone into the furnace, can reduce the corrupting of sulfur for equipment observably so as to attain the request of environment protection; It can continuously run for a long time and fault ratio is low extremely. According to the position cyclone separator being laid, CFB boiler is differentiated as high temperature CFB boiler and medium temperature CFB boiler.
