Abstract: Abstract:Taking the 2×680MW ultra supercritical unit as example, the operation mode of the booster fan and the induced draft fan after the flue gas bypass was cancelled was introduced. The influence of operation stability of the booster fan on operation reliability of the unit was expounded. The optimized control strategy was given, and the stable operation of the unit was ensured.
