CYCLONE DEVICE OF FLUIDINZED BED COMBUSTION DEVICE

摘要

PROBLEM TO BE SOLVED: To drastically prolong the life of a cyclone device by preventing corrosion in the cyclone device of a circulation fluidized bed combustion device, which is caused in the case of using substance containing chlorine such as municipal waste and industrial waste as fuel. SOLUTION: In the cyclone device 1 of a circulation fluidized bed combustion device in which mixed fluid of combustion gas and a fluid medium supplied from a circulation filuidized bed combustion furnace is accepted and separated into combustion gas and the fluidized medium, the cyclone device 1 is formed into a tangential type cyclone device equipped with a cyclone cylinder 2 and an exhaust cylinder 3 or formed into a volute type cyclone device and also the cyclone cylinder 2 is formed into forced-cooling structure or fire resistant wall structure and the exhaust cylinder 3 is formed into forced cooling structure.
