摘要
通过对比燃气锅炉与普通煤粉炉的污染排放特性,指出燃气锅炉虽然整体污染较小,但NO_(x)的生成与排放问题尤为突出。研究表明,低氮燃烧技术相比尾部脱硝具有主动控制、经济高效和适用广泛等优势。阐述了工业煤气锅炉NO_(x)的生成机理及关键影响因素,并详细介绍了当前主流的低氮燃烧技术。研究成果可为100 MW级煤气发电机组工程实践提供技术参考,对同类机组的低氮改造具有指导意义。
By comparing the pollution emission characteristics of gas boilers and ordinary pulverized coal boilers,it is pointed out that although gas boilers have less overall pollution,the problem of NO_(x) generation and emission is particularly prominent.Research shows that low-NO_(x) combustion technology has advantages over tail-end denitrification,such as active control,costeffectiveness,and wide applicability.This paper elaborates on the generation mechanism and key influencing factors of NO_(x) in industrial gas-fired boilers and details current mainstream low-NO_(x) combustion technologies.The research results can provide technical reference for the engineering practice of 100 MW-class gas generation units and have guiding significance for the low-NO_(x) renovation of similar units.
