翅片管散热器据中国散热器网为了稳定燃烧，若燃煤的挥发分、发热量降低，必须增加过量空气系数，则锅炉炉膛烟气温度必然降低，水冷壁的蒸发量下降，外装式减速滚筒由炉膛的辐射换热量公式可知，炉膛烟气温度的降低对辐射换热量的影响是4次幂的关系。

　为了维持锅炉的蒸发量，需按相同的空燃比增加燃料和空气，烟气流量增加，博山消防泵因烟道通流面积不变，过热器所在烟道的烟气流速也增加，根据稳态强制对流的准则方程得，烟气流速的增加对烟气侧对流换热系数的影响是烟气流速的n次幂，n＝0.6－0.65。

　　翅片管散热器综上所述，燃煤的挥发分和发热量降低，较多的减少了炉膛辐射换热量，而较少的增加了过热器的对流换热量，即水冷壁的吸热比例有所下降，过热器的吸热比例上升。

　　翅片管散热器如果煤种的发热量低于设计煤种，则燃尽时间延长，过量空气系数大于设计值，理论燃烧温度降低，炉膛内的烟气温度也降低，使较少的灰分熔化、蒸发，水冷壁的污染程度降低，污染系数增加。反之，污染系数降低。翅片管散热器沈阳散热器
