Structure Of SHX CFB Hot Water Boiler

The structure of QXX circulating fluidized bed hot water boiler is simple and compact, and the boiler is composed of combustion equipment, coal feeding device, water cooling system, separator, coal economizer, air preheater, steel frame, escalator and furnace wall, and the whole steel frame structure is adopted. The furnace is arranged before the furnace. The air required for combustion is provided by one or two air blower. A large number of smoke produced by the combustion of fuel in the furnace is carried. The gas and material are separated by the separator. The separated materials are returned to the furnace to reburn through the return feeder.

Model Parameter Of SHX CFB Hot Water Boiler

The QXX circulating fluidized bed hot water boiler is arranged in order of combustor, separator and tail flue to ensure good sealing performance. The high temperature zone adopts a full film wall seal structure, full suspension type, fixed expansion center, aggregate leg and furnace wall water wall composite expansion, improve operation reliability and reduce heat loss. The temperature in the bed can be adjusted conveniently by adjusting the coal supply, primary air and the two air volume and their proportioning, and the stock of the bed.
