摘　　要：本文以南京市2014年为例,满足规模以上工业企业供热供电量,燃气热电联产相对于燃煤热电联产节标煤量160.6万t,减排NOx量1 211.3t。结果表明燃气-蒸汽联合循环机组的环保效益优于燃煤机组,并且燃气热电联产在减轻南京市雾霾天气效果方面更为显著,气源充足地区实施"煤改气"顺应发展潮流。同时,根据南京市全年发电数据,发出同样多的电力,9F机组相对于燃煤机组节标煤量199.4万t,但多排出NOx量4 002.9t。可见,燃气轮机机组节能减排方面仍有很大的提升空间,国内燃气轮机排放标准应适时作出同步修改,使燃气轮机综合效益更上一层楼。This paper took the city of Nanjing in 2014 as an example. For meeting heating supply of the industrial enterprises above designated size heating supply,compared with coal-fired cogeneration section,gas-fired cogeneration saved 1. 606 million t standard coal and reduced 1 211. 3t NOxemission. The result showed the gas-steam combined cycle unit was superior to the environmental benefits of coal-fired units and the gas cogeneration was more significant in reducing the haze of Nanjing. The implementation of＂the coal to gas＂in the region with sufficient natural gas supply keeps up with the trend of the development. At the same time,according to the Nanjing power generation data throughout the year,9F unit saved 1. 994 million t standard coal,but discharged 4 002. 9 t NOxemission more than coal-fired cogeneration section when sending the same amount of electricity. As is seen,gas turbine unit has a lot of things to do in the aspects of energy conservation and emissions reduction. Emission standards of domestic gas turbines should be synchronously revised in due time,to further enhance their own comprehensive benefits.
