Experimental Study on Wet Desulphurization System of Large-Scale Thermal Power Plant with Ammonia Soda Solid Waste (White Mud)
In this paper, a field experiment of gas wet desulphurization with white mud and gypsum has been taken on one thermal power plant under the condition that the desulphurization system has not been renovated. the experimental result shows that the desulphurization ability of white mud is about 2% higher than limestone under the same PH value, so it’s feasible to apply the white mud as desulfurizer to the desulphurization system of large-scale thermal power plant, and the gypsum obtained after the desulphurization is better than that in limestone system, then the waste is all utilized. However, in practice, there is a need to increase the equipments for the corresponding slurry storage, preparation and supply, and also a capacity assessment for the dewatering system, wastes water system and process water system.
