摘　　要：介绍了NO_x的生成原因与目前国内外采用较多的控制技术,在对这些技术进行分析比较的基础上提出了此次技术改造的思路,采用摆动式低NO_x双相燃烧器+外燃式燃烧器+墙式可调式燃尽风装置有机融合的墙式分级送风燃烧技术,对410 t/h煤粉锅炉进行改造,取得了节油、节煤和减排的三重效果。该技术具有良好的推广价值。The generating causes of NO, and the worldwide commonly used control technologies were introduced. Based on analysis and comparison among these technologies, mentality of this technical reformation was determined. The adoption of wall type grading air supply combustion technology which integrated oscillating low NOx biphase combustor ＋ external -burning combustor ＋ wall type adjustable over fire air plant on the reformation of 410t/h coal fired boiler achieved triple results of oil saving,coal saving and emission reduction. This technology is thus proved to have high promotion value.
