Dongfang power plant came across many unqualified cases in the year of producing FGD gypsum. By analyzing the cause of unqualified gypsum in Dongfang power plant
it is found out that the main influencing factors of the quality include the operating conditions deviating from the design parameter of desulfurization system
the limited mixed burning of coal
the low efficiency of ESP and the insufficient output of gypsum cyclone separator. Therefore
this paper puts forward three improvement approaches:by controlling the entrance flue gas
by controlling the operational parameters of desulfurization system
and by strengthening the analysis work in environmental laboratory.
