The Analysis and Operation Control for the Gypsum’s Low Purity of Wet FGD

Gypsum is the main product of wet desulfurization, combined with the actual operating conditions of desulfurization unit, the factors affecting the purity of gypsum is analyzed. Combining with the comprehensive utilization of gypsum requirements, from every aspect of characteristics of coal, limestone’s quality and operation control, improve the gypsum’s quality of wet desulfurization in coal-fired plant.
