摘　　要：结合上海锅炉厂生产的300 MW现役发电机组收集到的相关参数进行理论分析及数值计算,采用EXCEL等辅助计算软件,针对过热器的问题提出三种方案,综合各方面因素考虑,采用了第三种方案切割低温过热器的受热面积以降低出口汽温,保护喷嘴的合理摆动和喷水减温水的使用量。Combining the relevant parameters collected from the 300 MW in-service generating units produced by Shanghai Boiler Plant,theoretical analysis and numerical calculation were carried out,and auxiliary calculation software such as EXCEL was used.Three options are proposed for the superheater problem,and the third option is adopted to cut the heating area of the low-temperature superheater to achieve a lower outlet steam temperature,protect the reasonable swing of the nozzles and the use of water jet to reduce the temperature of thewater.

关 键 词：煤种 低温过热器 受热面积 出口蒸汽温度
