火电厂氮氧化减排及SCR烟气脱硝技术

NO_(x) reduction and SCR flue gas denitration technology in thermal power plant

氮氧化物排放中最多的类型企业是火电厂,同时我国每年的火电厂的数量和装机容量持续增长,这是最主要的原因。我国针对火电厂的情况,在2010年—2011年这两年内出台了新的排放标准和政策。在此之后我国不断的研发火电厂的SCR烟气脱硝技术。在该技术取得一定成绩后,我国火电厂的SCR烟气脱硝设备的数量在持续的增长。从而实现降低氮氧化物的目标。因此我国氮氧化物排放量最高的年份是在2011年,之后每年的氮氧化物排放量数值都在降低。讲解火电厂对氮氧化物的减排的技术,其中主要讲解SCR烟气脱硝技术的相关理论和流程。体现出SCR烟气脱硝技术是我国火电厂氮氧化物减排技术中的核心技术。

The thermal power plant is the most important type of enterprise in NO_(x) emission.At the same time,the number and installed capacity of thermal power plants in China continue to grow every year,which is the main reason.According to the situation of thermal power plants in China,new emission standards and policies were issued in 2010-2011.After that,China continues to research and develop SCR flue gas denitration Technology in thermal power plants.After certain achievements have been made in this technology,the number of SCR Flue gas denitrification equipment in thermal power plants in China is growing continuously.Thus,the goal of reducing NO_(x) is achieved.Therefore,the year of the highest NO_(x) emissions in China is 2011,and the annual NO_(x) emissions are decreasing.The technology of reducing NO x in thermal power plant is introduced,including the related theory and flow of SCR flue gas denitrification technology.It shows that SCR flue gas denitration technology is the core technology of NO_(x) emission reduction technology in thermal power plants in China.
