摘要
本文从新的角度指出了我国现行的炉膛及分隔屏过热器热力计算中存在的问题:1.分隔屏的计算结果反映的传热规律与实际运行情况相反。2.没有充分反映分隔屏、后屏的汽温随烟温的变化幅度。经过论证,提出了分隔屏传热计算的合理方法,在典型的300MW机组上进行了实际应用,取得了与实测结果相当吻合的曲线关系,证明本文的构思和方法是正确的。可为300MW、600MW机组的设计和运行提供参考。
Two problems related to the present heat transfer calculation for utilityboiler furnace and platen superheater are discussed in the paper. A modi fied calculation method is proposed and the calculation results agree very well with the experimental data. It can offer a reference for the design and operation of 300MW and 600MW units.
