摘要

随着我国经济实力的日益增强,耗电量逐步加大。从而导致燃煤机组燃烧所产生的NOx等有害物质将越来越多。简要介绍燃煤电厂的选择性催化还原(SCR)、选择性非催化还原(SNCR)、混合SNCR-SCR的脱硝原理、特点、影响因素和工程应用,并对3种脱硝技术进行了详细的工艺比较。
        China's economic strength is increasing,power consumption is gradually increasing. And then leads to combustion of coal-fired generating units of nitrogen oxides and other harmful substances will be more and more. The selective catalytic reduction( SCR),selective non catalytic reduction( SNCR),Hybrid SNCR-SCR denitrification principle for coal-fired power plant and its influencing factors and the engineering application have been briefly presented. Detailed comparison process of the three kinds of denitration technology.
