Which mill is the best for desulfurization in power plants?
More than 90% of domestic thermal power plants use limestone-gypsum wet desulfurization. Limestone-gypsum wet desulfurization requires the production of a desulfurizer, which is mainly composed of limestone powder or calcium powder and mixed slurry of other stone powders and water, among which limestone powder is widely used.
