【摘要】 我国水泥行业产量巨大、污染严重,是一大NOx排放源。随着国家污染物排放标准的逐渐严格,各企业环保压力增大,水泥窑炉低氮减排技术引起了大家的广泛关注。一般的降氮措施有燃烧前处理、燃烧中控制和燃烧后脱硝三个方面,本文重点关注降氮潜力巨大、效果明显的燃烧中控制技术,概括总结了水泥窑炉氮氧化物生成机理及低氮燃烧技术的发展现状,指出了当前存在问题,为未来实现深度低氮减排夯实基础。更多还原

【Abstract】 With huge output and serious pollution, our cement industry is a major source of NOx emissions. The national pollutant emission standard is getting stricter and stricter, the environmental protection pressure of various enterprises is becoming more and more huge. Now the low-nitrogen emission-reduction technology of cement rotary kiln has attracted wide attention. Generally, there are three aspects for low nitrogen emission measures:pretreatment before combustion, combustion control and denitration after combustion. The article focuses on combustion control that is tremendous in reducing nitrogen potential and effective. This article summarizes the mechanism of nitrogen oxides and the present situation of low nitrogen combustion technology, points out the existing problems in this field, realizes the depth of low-nitrogen emissions solid foundation for the future.更多还原
