摘要
在原苏联《锅炉机组热力计算标准方法》基础上，提出了“两大块”炉膛换热计算方法，并针对燃用烟煤的国产ＨＧ－６７０／１４０－９型锅炉进行了多种炉膛换热计算的对比分析。“两大块”方法简化了炉膛换热计算；直接给出屏式过热器壁温计算入口断面烟气温度参数；计算结果与运行实际具有更好的吻合性．
On the basis of“The Standard Method of Boiler Heating Calculation”developed by original soviet union, the boiler furnace heating calculating method of“two great region”is pre sented. Analysis is made by contrast to many boiler heating calculating methods for HG- 670/140- 9 type boiler burning biuminous coals. The calculating method of two great region simplifies amount of furnace heat transfer calculation and provides smoke temperature directly on calculating section in calculation of screen type superheater wall surface temperature.The calculating results have better coinedenee function with running practice than the standard method.
