乌拉山电厂100MW燃煤机组低NO_x切圆燃烧技术研究

Low NO_x Combustion Technology for Tangential Firing System of 410 t/h Coal-fired Boilers in Wulashan Power Plant

介绍乌拉山电厂100MW燃煤机组进行的低NOx燃烧系统改造及改造中所采取的基本措施、运行结果。改造后的低NOx燃烧系统，在不要求显著投资、大的空间和额外运行费用的条件下，可大幅度降低NOx的排放量，并对锅炉的运行经济性有所改善。

This article introduces the retrofit of low Nox combustion system of 410 t/h coal-fired boilers in Wulashan Power Plant,and the main measures adopted during retrofit.After retrofit,the Nox emission from the boiler has been greatly reduced and the operation economics has been improved as well,while the retrofit cost,required space and additional operational cost are all inexpensive.
