再燃降NOx技术在我国的研究现状及发展前景

近年来,燃煤电厂NOx的排放量逐渐增加,成为环境污染的主要污染物之一.在目前现行的降NOx技术中,再燃降NOx技术凭借其良好的处理效果、锅炉改造量较小等优势逐渐成为燃煤电厂降低NOx的主要技术手段之一.通过介绍目前已有的几种再燃技术,分析其各自的优缺点和应用情况,旨在找到一种适合我国燃煤电厂实际国情的再燃技术,为今后NOx的减量排放起到指导性的作用.

Present situation and development of the technology of NOx control through reburning in China

In recent years, plants NOx missioned by coal fired power increased gradually,be- come one of the main pollutants of environmental pollution.At all of the technology which used to drop NOx, reburning technology becomes one of the most important technologies with its good treatment effect.By introducing the existing several reburning technologies,analyzes their advantages,disadvantages and application.It is in order to find a suitable reburningtech- nology for the coal fired power plants of China,and,to work as a guiding role for the future of NOx emissions reduction.
