ANALYSIS OF DESIGN FOR SWIRLING PULVERIZED COAL BURNERS WITH LOW NOx EMISSION
摘要
分析了我国电站锅炉低NOx旋流燃烧器的使用状况和NOx排放现状
总结了旋流燃烧器实现低NOx燃烧的技术要素。分析表明
二次风的配给、一次风的浓缩、一次风喷口结构和一次风预热等是降低NOx排放的重要措施。同时
讨论了低NOx旋流燃烧器的研究发展方向
可为旋流燃烧器的选型和设计提供参考。
Abstract
The application situation of swirling burners with low NOx emission on utility boilers and status quo of NOx emission in China have been investigated and analysed
the essential factors for realizing low NOx combustion using swirling burner being summarized up.Analysis shows that the distribution of secondary air
the enrichment of primary air
the structure of primary air jet
and the preheating of primary air etc.are important measures for reducing NOx emission.At the same time
the direction for research and development of swirling burners with low NOx emission has been discussed
providing certain reference for type-selection and disign of swirling burners.
