Directing against the problem of lower efficiency of the electrostatic precipitator(EP) due to burning Zhungeer coal for 2×600 MW units in Daihai Power Plant
it is discovered from analysis that the main causes are variation of boiler's flue gas temperature and pressure
as well as the change of coal quality and composition of ash etc.
and solving measure being put forward
directly spraying water or SO2 into tail flue duct of boilers and before the inlet of EP.After implementation
the specific resistance of dust is reduced and the increased moisture of dust promoting dust to deposit
