Fuel Fired Circulating Fluidized Bed Boiler , Steam Turbine Power Station Boiler
Product Description
CFB with its superior encironmental characteristics,fuel adaptability and good running adaptability has been widely welcomed.CFB good at load capacity and peaking capacity,fuel preparation system is simple,excellent slag discharged actively,no secondary ash polluction,easy to implement utilization,investment and operation cost is moderate and thus favored by the users.Currently widely used in small-scale,CHP plants,boimass power plants and waste incineration plants.
Features
• Boiler sheet separator cyclone and air-cooled (water cooled)cyclone separator
• Boiler Run efficiency up to 90%
• Tail superheater area using air-cooled(water cooled)wall enclosure
• Rear fender economizer furnace wall:the guard plate frame light furnace wall,boiler tightness
• Design of steel structures:Using finite element analysis software of the boiler structure was accurately calculated to ensure that the load distribution is reasonable
• Optimizing a secondary air ratio can be reduced auxiliary power,strengthening extension to extend the disturbance in the furnace flue gas residence time,improve thermal efficiency of the boiler
• Furnace section play,smoke long residence time in the furnace,the furnace up speed is low,the funace circulating volume,improve the boiler burnout rate,colleagues,greatly reducing the wear of the furnace water wall region
