切割塔顶不凝气做燃料的燃烧器的在线低氮改造

Odification of Burner Using Non-condensing Gas as Fuel

加热炉在不停炉的情况下,对燃烧器进行改造更新,使改造后的加热炉燃烧效率更高,降低燃烧过程中NOx的产生量。在改造过程中,通过观测燃烧状况,检测加热炉烟囱污染物排放数据,对低氮燃烧器的改造效果进行评估,针对运行中出现的燃料气组分变化较大的工况,对燃烧器进行深入优化,使燃烧火焰稳定,烟囱污染物排放控制在环保标准以内,进一步提高了燃烧器的性能。结合工程实例,对低氮燃烧器选型设计、低氮燃烧控制措施、现场操作优化策略等进行深入分析,得为石化同行提供低氮改造决策参考。

In the case of the heating furnace without furnace,the burner was reformed to update,so that the improved heating furnace combustion efficiency higher,reduce the production of NOx in the combustion process.In the process of transformation,by observing the combustion situation,detection of furnace stack emissions,according to the low nitrogen transformation effect evaluation of burner,in view of the fuel gas composition changes occurred in the use of larger conditions,burner for further optimization of the combustion flame stability,chimney emission control within the environmental protection standard,further improve the performance of the burner.Combined with engineering examples,the selection design of low nitrogen burners,low nitrogen combustion control measures and field operation optimization strategies are deeply analyzed to provide reference for petrochemical peers to make decisions on low nitrogen transformation.
