电厂抽汽供热改造节能环保及经济性分析

摘要

介绍了神华天津国华盘山发电有限责任公司(以下简称盘山电厂)打孔抽汽供热改造方案,对采用该方案进行供热的节能、环保及经济效益进行了分析.结果表明,采用该供热方案每年可节约标煤13.82万t,二氧化硫、氮氧化物、烟尘将分别减排约1388.1t/a、1755.5t/a和2307.5t/a,投资回收期约5年.%This paper introduces the heat supply retrofit scheme of steam-extraction in Panshan power plant,and the economy,energy conservation and emission reduction are analyzed.The results indicate that 138200 tons of standard coal can be saved by applying this method,and the emission of SO2,NOx and flue dust can be reduced by 1388.1 t/a,1755.5 t/a and 2307.5 t/a respectively zwith an investment recovery period of 5 years.
