火电厂氮氧化物污染防治研究

Research on Prevention and Control of Nitrogen Oxide Pollution in Heat-engine Plant

我国NOx污染日趋严重，火力发电厂又是NOx排放的主要污染源。针对国家对电力工业的节能减排政策，通过分析火电厂氮氧化物产生机理，总结各种氮氧化物的净化方法，考虑技术经济发展水平和电力企业承受能力，提出近期火电厂氮氧化物污染防治的主要途径。

Nitrogen oxide pollution is more and more serious which mostly comes from the heat-engine plant. Aim at the national energy saving emission reduction policy to power industry, this paper tries to propose the main ways of thermal power plant nitrogen oxide pollution prevention and control, by analyzing the thermal power plant nitrogen oxide mechanism, sumruing up the various nitrogen oxides purification method, considering the technical level of economic development and affordabihty of power enterprises.
