60TPH 3.82MPa CFBC Boiler

"60TPH 3.82MPa CFBC Boiler" is listed under  BoilersCategory

60t/h CFBC boiler’s designing is according to CFBC, matching turbo-generating set and matching steam turbine for starting and operation with cyclone separator for material circulation and balanced ventilation. Because of adoption of new CFBC technology, the structure is simple and compact, similar to structure of pulverized coal fired boiler. The boiler proper is comprised of combustion equipment, coal feeder, water-cooling system, and high temperature cyclone separator, super heater, air heater, steel structure, stairs and furnace walls. Between furnace and convection draft, there are 2 sets of ID 3.4m cyclone separator, whose shall be made of 8mm steel. The upper of it is sophisticated form the lower of it is cone-shape. There are anti-wear and anti-fire layer in flue gas part, between steel and above layer, there is keep-warm material with nail and plate to fix. The convection part between sophisticated form and cone-shape, there is supporting device on the steel beam. The loopback device uses auto-balanced J type loopback material valve, whose features are that automatically set up material sealing after starting of the boiler, when adding air, it can realize materials’ automatically circulation. In the tail draft, there are economizers superheaters of both low and high temperature and air pre-heater. In superheater system, there is spry water desuperheater between them. This boiler uses two steps air: primary air come to furnace from WC wind box and head, secondary air comes to furnace from front and wear side of the combustion chamber. There are 3 feeding coal points, and limestone can be through the feeding coal device into furnace. At the bottom of furnace, there is WC wind chamber. There are 2 sets to starting fire device by light diesel. In about 900? bed, fuel, air and limestone can mix in furnace dense region. The coal discharging the heat in fluidized form and materials, flue gas and WC wall heating surface could change heat with each other. The limestone transformed into CaO and CO2, CaO+ SO2? CaSO4. So reach the desulfurizing in the furnace. The flue gas come out with 139? discharging outside the boiler proper. The solid would return to the furnace to realize circulation. The center nominal height of drum is 27550mm. the depth of front and rear pillar is 13100mm with width 7100mm between them. Steam and water circulation system includes rear economizer, drum, heating surface, WC wall and convection draft superheater. This boiler uses single main line, which could be divided into 2 ways, one way to spray desuperheater, the other to inlet header of economizer with 2 pipes to adjust the load. The water came firstly from inlet header of economizer, then passes low-temperature economizer tube tank, after heating, goes into middle header, then goes into high-temperature economizer tube tank, then passes outlet header of economizer, at last goes into drum. Between drum and inlet header of low-temperature economizer, there is tubes to realize circulation for economizer. The steam and water circulation system includes drum, down comer, WC wall, tubes.
