摘要
本文根据700 MW高效超超临界CFB锅炉的设计条件,充分吸收350 MW~660 MW超临界CFB的设计、运行经验,提出了700 MW高效超超临界CFB锅炉方案及整体布置。锅炉总体采用M型布置,单炉膛单布风板结构,炉膛内布置屏式受热面,不设置外置式换热器,炉后布置高温冷却式旋风分离器,尾部采用双烟道挡板调温,热力系统设计合理,性能可靠性高,可有效实现高效超超临界蒸汽参数与CFB锅炉燃烧技术相结合。
According to the design conditions of 700 MW high efficiency ultra supercritical CFB boiler and fully absorbing the design and operation experience of 350 MW-660 MW supercritical CFB boiler,this paper puts forward the scheme and overall layout of 700 MW high efficiency ultra supercritical CFB boiler.The overall arrangement of the boiler is M-type,with single furnace and single air distribution plate structure.The platen type heating surface is arranged in the furnace,without external heat exchanger.The high temperature cooling cyclones are arranged behind the furnace,and the temperature is adjusted by double flue baffle at the rear pass.The thermal system design is reasonable and the performance reliability is high,which effectively realizes the combination of high-efficiency ultra supercritical steam parameters and CFB boiler combustion technology.
