FLUIDIZED BED BOILER TO IMPROVE CAPABLE TO IMPROVE CORROSION RESISTANCE AND HEAT RECOVERY RATE OF A CONNECTING DUCT INSTALLED BETWEEN A COMBUSTION FURNACE AND A CYCLONE

摘要

PURPOSE: A fluidized bed boiler is provided to prevent the blockage of a connecting duct and improve dust collection efficiency by increasing fluidization in the connecting duct.;CONSTITUTION: A fluidized bed boiler comprises a combustion furnace(10), a cyclone(20), a boiler(30), and a connecting duct(40). The combustion furnace burns RDF(Refuse Derived Fuel) of domestic waste in a fluidized state. The cyclone divides combustion gas and particles generated through combustion and collects the particles. The boiler is connected to the cyclone and generates vapor by boiling the water. The connecting duct connects the combustion furnace and the cyclone.;COPYRIGHT KIPO 2012
