固定源氮氧化物排放及控制技术应用

Emission and control of nitrogen oxides from stationary sources

固定源是氮氧化物排放的一个主要来源。通过对主要固定源氮氧化物生成机理及现有的排放控制技术进行论述,分析我国固定源氮氧化物排放的实际情况,提出我国固定源氮氧化物排放控制还处于起步阶段,氮氧化物排放标准相对宽松,氮氧化物排放控制技术有待进一步普及,并提出固定源氮氧化物排放治理的一些建议。

Stationary sources, including fuel fired power plant and other industrial buildings, have been growing as an more and more important contributor of nitrogen oxides emission in China. Based on generation mechanisms of nitrogen oxides and dominant control technologies, this paper analyzed the emission and control of nitrogen oxides from stationary sources in China. The evidence from our analysis of the emission and control of nitrogen oxides from stationary sources suggests that the control of nitrogen oxides is just in beginning phase, compared to the sulphur dioxide control, and the emission criterion of nitrogen oxides is not severe in China, meanwhile the popularization of mature control techniques for nitrogen oxides emission is not enough. Finally, some suggests were presented for strengthening abilities to control the emission of nitrogen oxides from stationary sources in China.
