Abstract： The desulfurization tower slurry tank of a certain thermal power plant has serious scaling. Analysis and detection of operating data， desulfurization slurry and scaling materials found that the F and P content in the scaling materials in the desulfurization tower is abnormal， which is the main factor of scaling in the desulfurization tower. By controlling the F and P content in the slurry， the scaling problem in the desulfurization tower can be significantly improved.

Keywords： wet desulfurization; scaling ; F and P exceed the standard values; preventive measures
