Analysis of the Causes of High Calcium Carbonate Content in Coal-Fired Power Plant Desulfurization Gypsum

Abstract:

In this paper, the problem of high calcium carbonate content of desulfurization gypsum using limestone - gypsum wet desulphurization technology in coal-fired power plants questions, recommendations in running process from the control of absorption tower pH, lime stone powder, lime powder fineness activity to solve the above problems.
