Reliability Improvement of Flue Gas System After Desulphurization Passby Cancellation
After the cancellation of desulphurization passby,there are two different methods for flue gas system reconstruction:one is the ID fan and FGD booster amalgamation ; the other is to retain booster fan.In terms of the two different methods,several aspects were analyzed,such as reliability interlock protection,optimization test of flue gas system,design and test of RB function of flue gas system.Combined with the engineering practice,the main optimization measures are proposed to improve the reliability control of flue gas system.
