摘　　要：全国不少地方采用高效协同控制技术对燃煤电厂脱硝、脱硫、除尘系统进一步扩容改造,使机组烟气污染物达到"超低排放"的目标。截至2014年底已有17台机组通过验收,达到"超低排放",低于天然气燃气轮机机组排放标准。这些业绩得到媒体广泛报道,燃煤电厂"超低排放"环保改造形成一股潮流。但是在技术、经济效益、环境效益方面仍有许多值得探讨的问题,还需冷静探讨分析,慎重对待。应该考虑多元化协同控制路线和社会整体环境效益的有利方案。The efficient coordination control technology is used in the further expansion for the denitration,desulphurization and dust removal system of many coal- fired power plants in China,making flue gas pollutants reach the target ＂Ultra- low Emission＂. By the end of 2014,17 units had been inspected and accepted,achieving ＂Ultra-low Emissions＂and lower than the natural gas turbine unit emission standards. These results have been widely reported and coal- fired power plants ＂Ultra- low Emission＂environmental transformation has formed a trend. But in terms of technology,economic benefits and environmental benefits,there are still many problems worthy to be discussed,still need to be calmly analyzed and treated seriously. The beneficial program,diversified coordinated control line and society as a whole,should be considered.
