降低NO_x污染的净化处理法

No_x POLLUTION PREVENTION

燃烧等带来的NOx是酸雨的主要来源。高温催化燃烧可抑制NOx的生成；选择催化还原法（SCR）为消除NOx的成熟技术，是处理燃煤电厂烟道气的必要措施；烟道气循环法和低NOx燃烧器法简单实用；在氧气存在下烃类化合物对NOx还原法较符合工业尾气的实际条件，因而是个活跃的研究领域。

NOx which comes from the combustioon of fossil fuels is the main source of the acid rain. The catalytic stabilized thermal (CSR) combustion can suppress the formation of NOx;the selective catalytic reduction (SCR) is the mature technique for NOx emission control, especially for coal-fired power plants, while the circulation of flue gas and the low NOx burner are the simple and efficient metho-ds for the same purpose The reduction of NOx.with hydrocarbons in the presence of oxygen can he used practically,since the situation is more similar wlth the really in-dustrial conditions, and becomes an active field for further investigation-
