火电厂烟气脱硝技术探析

摘要

Introduced flue gas denitrification technology selective catalytic reduction SCR , selective non-catalytic reduction technology SNCR three processes, as well as hybrid SNCR -SCR.Both the strengths and weaknesses of the process as well as the thermal power plant using hybrid SNCR-SCR flue gas denitrification technology more reason drawn on the basis of three processes .%　　介绍了烟气脱硝技术中的选择性催化还原技术SCR、选择性非催化还原技术SNCR以及混合型SNCR-SCR三种工艺。在比较三种工艺的基础上得出前两者工艺的优势和不足以及当前火电厂使用SNCR-SCR混合型烟气脱硝技术较多的原因所在。
