摘　　要：分析了水合肼在温度为700-1 000℃,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.A study is conducted on hydrazine hydrate purified NOx by selective non-catalytic reduction（SNCR） under the conditions of temperature 700 - 1 000℃, 02 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.
