摘要
催化还原(SCR)和非催化还原(NSCR)是针对氮氧化物产生以后使之还原成氮气从而减少氮氧化物污染而采用的脱硝技术。过程催化还原(PSCR)技术旨在化石燃料燃烧过程中让催化剂参与进去阻止氮气与氧气反应,从源头控制氮氧化物产生。在无组织排放的情况下,氮氧化物的排放值可以控制在20×10^(-6)以内。
Selective catalytic reduction(SCR)and non-selective catalytic reduction(NSCR)are two denitrification technologies for reducing formed nitrogen oxides to nitrogen and minimizing nitrogen oxide pollution.Process-selective catalytic reduction technique is designed to control the nitrogen oxide emission from the source using catalyst to stop the reaction of nitrogen with oxygen during the combustion of fossil fuels.In the case of unorganized emission,nitrogen oxide emission could be controlled within 20×10^(-6).
