Flue Gas Desulfurization Systerm - free-valve
Flue gas desulfurization is the main action to control the discharge of SO2 in the coal power plant . There are several desulfurization process in the international market , that is wet desulfurization ,dry desulfurization ,semi dry desulfurization and ammonia process of desulfurization.Flue Gas Desulfurization (FGD) Plants | Air Quality,,The flue gas desulfurization (FGD) plant removes sulfur dioxides (SO 2) from flue gas produced by boilers, furnaces, and other sources. Mitsubishi Hitachi Power Systems (MHPS) effectively contributes to the prevention of air pollution through its wet limestone-gypsum FGD process and seawater FGD process, and both processes can treat a large,FLUE GAS DESULFURIZATION TECHNOLOGY VALUATION,Wet flue gas desulfurization (FGD) has its roots before the Second World War. With clean air legislation in 1970, wet FGD became the process of choice because it was the only option that had been developed. The lime spray dryer (LSD) FGD technology soon became available, but its focus was on low-sulfur fuels and low removal requirements.
