摘要
介绍和分析了选择性催化还原(SCR)技术烟气脱硝工艺及其化学反应机理。阐述了影响SCR脱硝效率的几个主要因素。并以福建后石电厂SCR裝置(高尘布置方式)为例总结分析了选择性催化还原脱硝技术对电站锅炉运行带来的系列性影响。并指出为保护环境,燃煤电站锅炉的NOX排放需得到有效控制。SCR技术将在中国NOX减排中得到广泛应用。
In order to meet the environmental protection demands,NOX emission of coal boilers should be controlled.This paper analyzes the selective catalyst reduction(SCR) technology for flue gas denitration and its chemical reduction mecha-nism.Taking SCR system of Fujian Houshi Power Plant for example,the influences of SCR system on boiler operation are summarized and analyzed,major factors influencing the denitration efficiency are described.It is expected that the SCR denitration technology will have broad application in China.
