1 240 t/h循环流化床结构、参数简介锅炉采用单汽包、自然循环、循环流化床燃烧方式,半露天布置。锅炉由一个膜式水冷壁炉膛,两台绝热式旋风分离器和一个由汽冷包墙包覆的尾部竖井(HRA)三部分组成。炉膛内布置有屏式受热面。锅炉共有4台给料装置,并预留有两个石灰石给料口,给料装置和石灰石口全部置于炉前。炉膛底部是由水冷壁管弯制围成的水冷风室,水冷风室
1 240 t / h circulating fluidized bed structure, parameters Brief introduction Boiler using single steam drum, natural circulation, circulating fluidized bed combustion, semi-open air layout. The boiler consists of a membrane water-cooled hearth, two adiabatic cyclones and a rear shaft (HRA) covered by a vapor-cooled envelope. The furnace is equipped with a screen heating surface. A total of four boiler feed device, and reserves two limestone feed port, feed device and limestone mouth all placed in front of the furnace. The bottom of the hearth is a water-cooled air chamber enclosed by a water-cooled wall tube, and a water-cooled air chamber
