Fluidized bed combustion boiler （FBC boiler）are widely used in industries such as building materials, chemicals, metallurgy, pharmaceuticals, etc. FBC boiler can use inferior coal instead of high-quality coal to generate high-temperature flue gas for direct or indirect heating The fluidized bed combustion boiler is to send coal (size of 0-10mm), into the air distributor in the boiler, and the high-pressure air will make the coal particles and furnace material boil through the air distributor. Due to the fact that coal particles only account for about 1% of the furnace material; the contact area with air during boiling combustion is large and the relative movement speed is fast; and the time from raw coal entering the furnace to being discharged from the furnace is long; thus, some low-quality coal with high ash content and low calorific value that are difficult to burn through in other furnace can also be stably and fully burned in FBC boiler. System A FBC boiler consists of three parts: a furnace bed, a furnace, and a mixing chamber. The furnace bed includes an air distribution box, air distribution plate, air cap, slag hole, etc; The furnace section includes vertical section, diffusion section, suspension section, and furnace door; The mixing room is connected to the dryer and is equipped with ash discharge doors, manhole doors, thermocouples, etc. Advantage a. capable of burning various low-quality coal and slag (with a calorific value greater than 6270KJ/KG); b. The furnace body is evenly heated and has a long service life, combustion efficiency can reach over 95%;
