Abstract:

A power plant has two units of 330MW subcritical coalfired units, and adopted gypsumlimestone wet type flue gas desulfurization system. Desulfurization system was equipped for each boiler and with one stacker. Abnormal scaling was found in desulfurization system operating. Base on this problem, analysis was carried out, and treatment measurements was indicated. Which is critical for the unit safety, reliability and economic.
