摘　　要：根据空气预热器冷端壁温的要求,提出了冷风预热的方法以及暖风器选择的原则。并指出,暖风器在机组负荷变化和环境温度变化时应进行核算,以满足对冷风温度的要求,同时,对冷风温度的调节提出了一些新的见解。Depending upon the requirements of cold end temperature of tube wall of air preheaters, the method of cold air preheating and the criterion of selection for air heater are put forward. For the variations of generating set load and the changes of environment temperature, the air heater should be checked to satisfy the requirement to the temperature of cold air, these are pointed out; and some new ideas for the adjustment of cold air temperatures are put forward.
