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

Abstract

[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.
