摘要
污染物NOx的排放日益严重地影响着环境、气候和人类的健康,成为一个迫切需要解决的问题。随着人们环保意识的增强,研究低NOx煤粉燃烧理论及技术和控制NOx的排放已成为当前热门课题,本文讨论了火电厂控制NOx排放的主要途径,并从火电厂SCR脱硝装置布置、催化剂型式、加氨系统和工艺流程等方面对火电厂应用该技术的运行情况及存在问题进行分析。对火电厂降低烟气中NOx的技术应用和推广具有重要意义。
The discharge of NOx has severely impacted on circumstance ,climate and health of mankind increasingly, so it has to be solved. Alongwith people＇s witting of environment protection, it becomes to be popular topic that studying the theory and technique of burning low NOx powdered coal and controlling the discharge of NOx. The study discussed the main pass of controlling the discharge of NOx, and analysised the operation and issues of SCR DENOx system in thermal power plant from arrangement of SCR equipment,a mmonia supply system,selection of catalyst. It is important to utilize and spread the techniaue of cut down the discharge of NOx
