1000 MW燃煤机组引风机与增压风机改造研究

Research on Reformation of Induced Draft Fan and Booster Fan for 1 000 MW Coal-fired Power Plant

[目的]为确保锅炉烟气系统的正常运行,国内燃煤发电机组实施超低排放改造后,引风机及增压风机需要进行改造。[方法]以某1000MW燃煤机组为例从技术角度对引风机及增压风机三种可行的改造方案(只改引风机、只改增压风机以及增引合并)进行了比较,并结合工程实际情况进行了经济计算。[结果]得出增引合并方案的综合技术经济性最优。[结论]此比选方法和改造方案对其他燃煤机组引风机改造有较高的参考价值。

[Introduction] In order to ensure the normal operation of the flue gas system of boiler,after the domestic coal-fired power plant is implemented with ultra-low emission reform,the induced draft fan and the booster fan need to be reform.[Method] Taking a 1 000 MW coal-fired unit as an example,the three possible reforming schemes of the induced draft fan and the booster fan (only the induced draft fan was changed,the booster fan was only changed,and the induced draft fan and booster fan were merged) were compared from the technical aspect,and made an economic calculation based on the actual unit.[Result] The result shows the merger scheme has lower cost.[Conclusion] This comparison method and modification scheme have high reference value for the induced draft fans reformation of other coal-fired power plant.
