摘要
煤燃烧生成的NO_x对生态环境有着严重的危害作用。随着环保要求的提高,国家制定了严格的法规来减少NO_x排放。针对目前的燃煤烟气脱硝现状,主要介绍了低氮燃烧技术、低温催化脱硝技术、选择性催化还原脱硝技术、选择性非催化还原脱硝技术和臭氧脱硝技术,并结合工程实际数据和实验室研究案例对其脱硝过程和效果进行描述,为燃煤烟气脱硝技术的实际应用提供参考。
NOx produced by coal combustion has a serious harm to the ecological environment. With the improvement of environmental protection requirements, the government has mandated stringent environmental legislations to reduce the NOx emissions. In view of the current status of coal-fired flue gas denitration, low-NOX combustion technology, low temperature catalytic denitration technology, selective catalytic reduction denitration technology, selective non catalytic reduction and ozone denitration technology were introduced. Combined＂ with actual engineering data and laboratory research cases, the process and effect of denitrification were described, which provided reference for the practical application of NOx removal from coal-fired flue gas.
