Optimization and realization of runback logic of main machine

Abstract

Abstract: Abstract:After the bypass damper of unit No.1 of Huadian International Zouxian Power Plant had been cancelled, a runback logic for main machine when the booster fan failed and tripped was designed. The main function of the runback logic is that after the booster fan failed and tripped, the runback logic will act, the unit will execute a series action automatically to reduce the unit load, the relevant mill exhauster will trip, the fuel feed will decrease, the target load of the unit will be reduced, will be put into furnace to help combustion. Then the fan and the whole unit can operate safely.

Key words: Keywords:runback (RB) logic, desulphurization, bypass damper, booster fan, mill exhauster, test
