摘　　要：对超临界空冷机组工业供热改造减温减压技术进行了研究,并以一超临界600 MW空冷机组为例,对不同的技术进行了论述。结果表明,3种技术各有优劣,应结合实际情况选择技术方案,同时机组进行工业蒸汽抽汽改造后,发电煤耗大幅度降低。This paper studied the temperature-reducing and decompression technology of industrial heating reform for supercritical air-cooling unit,and discussed different technologies with a supercritical600MW air-cooling unit as an example.The results showed that the three technologies have their own advantages and disadvantages,so that the technical solution should be selected according to the actual situation;after the industrial steam extraction reform of unit,the coal consumption of power generation is greatly reduced.
