【摘要】 对秦皇岛热电厂2号锅炉燃烧器的技术改造结果表明，在旋流燃烧器一次风出口加装齿形煤粉增浓器，可以实现浓淡分离燃烧，提高锅炉的低负荷稳燃性能和效率。这种方法简单易行，值得应用于旋流燃烧器的技术改造。更多还原

【Abstract】 The tooth-typed concentration enrichment apparatus is installed at the primary air exit ofthe swirl burners in Boiler No.2 of Qinhuangdao Power Plant. By this way enriched-diluted combustionhas been realized. The experimental results show that good flame stability and high efficiency areachieved. This type of reform method is simple and is widely used.更多还原
