The image analysis and thermal-gravity study on the components of gypsum in the desulphurization productions from WFGD

In the paper,the image method and thermogravity analysis were applied in analyzing the physics construction and chemical components of the desulphurization productions.The analyzing result showed that the gypsum concentration was high,the mean process production in the residuals was also high because of the sulfite oxidation in slurry tank was not enough.Improving the oxidation system in the tank the desulphurization productions could meet the industry and civilian need.The method can rapidly and conveniently analyze the main components of the desulphurization productions,which is a novel method.
