600MW进口亚临界旋流煤粉燃烧锅炉炉内低氮改造技术

Furnace Low-NO_x Transformation Technology for Imported 600MW Subcritical Swirl Pulverized Coal Boiler

近年来,我国环保要求日趋严格,对国内电站锅炉机组污染物排放更是提出了史无前例的高要求。针对某电厂进口的日本IHI公司机组,采用旋流燃烧技术的600 MW墙式对冲锅炉,通过对锅炉运行现状的分析,了解NO_x排放偏高的原因,实施了相应的炉内低氮改造措施,并达到了比较理想的效果。

In recent years, with China^s environmental protection requirements more and more strict, the unprecedented high requirements have been put forward to the discharge of pollutants for the domestic power plant boiler unit. With the analyzing of operation informa- tion and the high discharging of NO~, the transformation measure was implemented and a- chieved ideal effect in A 600 MW swirl pulverized coal boiler unit which was imported from Japanese IHI company.
