中文摘要: 分析了水合肼在温度为700~1000℃,氧含量为3.6%~11.4%,NO浓度为450×10-6(体积比)左右时,选择性非催化还原法对烟气中NOx的脱除效果.研究结果表明,用水合肼作为脱硝还原剂时,肼可直接分解产生NH2活性基元,且合适的高温和较低的O2含量有利于NOx的还原脱除.
Abstract:A study is conducted on hydrazine hydrate purified NOx by selective non-catalytic reduction(SNCR) under the conditions of temperature 700~1 000℃, O2 content 3.6%~11.4%, and NO concentration 450×10-6(v/v) around.It is indicated that as reducing agent, hydrazine could directly decompose to produce NH2 active groups, and appropriate high temperature and low O2 contents are beneficial to the reduction of NOx.
keywords: hydrazine selective non-catalytic reduction NOx
