燃气锅炉低氮燃烧技术的应用研究

Application Research on Low Nitrogen Combustion Technology in Gas Boiler

近年来,我国大气污染日趋严重,环保压力越来越大,随着“煤改气”的逐渐深入,焦作市逐步实行更严格的排放要求,由原来的氮氧化物排放≤150 mg改为≤80 mg或≤30 mg,也就是所谓的气改气(超低氮排放≤30 mg/m3)。本文以焦煤公司演马庄矿、九里山矿、古汉山矿和中马村矿为例,介绍了在实施“气化焦作”关停改造燃煤锅炉行动中如何拆除燃煤锅炉、改建燃气锅炉,并进行超低氮燃烧技术改造的应用研究及效果评价。

In recent years,China’s air pollution has become increasingly serious,and environmental protection pressure is increasing.With the development of“burning gas instead of coal”,Jiaozuo gradually implemented stricter emission requirements.The original nitrogen oxide emission criterion is less than 150 mg,but now is less than 80 mg or 30 mg,which is the so-called“gas to gas”(ultra-low nitrogen emission≤30 mg/m3).This paper used Yanjiazhuang Mine,Jiulishan Mine,Guhanshan Mine,and Zhongmacun Mine of the Henan Jiaozuo Coal Energy Co.,Ltd.as examples to introduce how to dismantle coal boilers and rebuild gas boilers in the implementation of the“Gasification Jiaozuo”closing and reforming coal boilers,and carried out the application research and effect evaluation of ultra-low nitrogen combustion technology transformation.
