| Abstract: | According to the problems of high moisture ratio of WGFD gypsum in a certain 350 MW power plant,analysis has been carried out on system operation mode and unit operation status based on desulfurization system operation status.The factors that effect gypsum moisture ratio have been pointed out,which include coal quality,flue dust removal efficiency,pH value of absorption tower slurry and solid content in slurry.Some measurements have been adopted to keep the gypsum water content fits the code requirements,which include strictly following the operation codes,controlling desulfurization parameters,increasing waste water discharging volume,ensuring dust collector efficency,reducing impurities and increasing the gypsum slurry purity,improving calcium sulfite oxidative degree. |
