摘要
在介绍烟气脱硝技术选择性催化还原技术SCR、选择性非催化还原技术SNCR以及SNCR与SCR混合烟气脱硝技术的基础上,对这3种技术进行了比较,认为SCR脱硝效果比较好,但工程造价高;SNCR工程造价低,但效率不高;所以目前工程多采用效率和造价均中等的SNCR与SCR混合型烟气脱硝技术。
On the base of introduction of the technology of NOx out of flue-gas, including selective catalytic reduction （SCR）, selective non-catalytic reduction （SNCR） and the mix of SNCR and SCR, this paper makes a comparison between three technologies. The result shows that SCR is more effective than the others, but the construction cost is high; SNCR＇s construction cost is lower than the others,but it＇s efficiency is low; therefore, the project adopts the mix of SNCR and SCR presently of which both efficiency and the construction cost are medium.
