Fluidized bed combustion boiler(FBC boiler) is a new tech of burning with fluidized bed principle.It’s very different to the stoker and burner.The fuel (coal) have to crash the granularity below 10mm,then feed into the hearth evenly by the lifter.The coal are burning like the fluidized bed above the hearth by the high pressure air from the blast caps which distribute under the hearth.The heating load can been controlled by the fuels supply,air volume,wind pressure and off-gas’temperature.FBC boiler is widely used for coal,coal sludge,sludge,slag,sand,chemical fertilizer,gypsum and plenty of other materials drying or calcination.
