660 MW燃煤机组并网前投脱硝技术实践

Technical Practice of Putting Denitration Device into Operation before Grid Connection for 660 MW Coal-fired Units

华能福州电厂660 MW燃煤机组利用现有条件,在未进行技术改造的前提下,通过合理配煤、提前投运高加等方法将脱硝入口烟气温度提高到297℃,在并网前投入脱硝装置实现了运行。简要介绍了满足并网前投入脱硝装置可以采取的方法,供同类机组参考。

Based on the existing conditions of 660 MW coal-fired units,without technical transformation,Fuzhou Power Plant of Huaneng International Power Co.,Ltd.raised the flue gas temperature at the denitration inlet to 297℃by means of reasonable coal blending and putting into operation the high-pressure heater in advance,and put the denitration system into operation before grid connection.This paper briefly introduced the methods that can be adopted to put denitration device into operation before grid connection for reference of similar units.
