摘要
当前,我国发电量总体中占据较大比重的是燃煤发电这一方式.燃煤发电会产生大量NOX等污染物,容易引发环境污染问题,诸如酸雨、光化学烟雾污染、灰霾天气等.燃煤电厂通常是采用选择性催化还原法(SCR)将氮氧化物去除,但是电厂SCR脱硝系统运行状态还不尽理想,因此需要积极地分析锅炉SCR脱硝系统中存在的各种问题,并提出针对性的改进策略.
At present,coal-fired power generation is the main way of generating electricity in China.Coal-fired power generation will produce a large number of nitrogen oxides and other pollutants,which easily lead to environmental pollution problems,such as acid rain,photochemical smog pollution,haze weather and so on.Selective Catalytic Reduction(SCR)is usually used to remove nitrogen oxides in coal-fired power plants,but the operation status of SCR denitrification system in power plants is not ideal.Therefore,it is necessary to actively analyze the problems existing in boiler SCR denitrification system and propose targeted improvement strategies.
