摘　　要：针对 42 0t/h锅炉存在主汽温、再热汽温偏低的问题 ,通过热力计算和尾部烟道三维流场数值模拟 。There was a persistent problem of excessively low superheater and reheater temperature in a 420 t/h boiler. On the basis of a thermodynamic calculation and the numerical simulation of a three dimensional flow field of the boiler tail section flue pass a set of comprehensive measures has been proposed to cope with the above cited excessively low steam temperature and the wear caused by fly ash.

关 键 词：锅炉 汽温偏低 飞灰磨损 模拟计算 综合治理
