Abstract:

The working principle of the wet electrostatic precipitator (WESP) is briefly described. Based on the application of 2×300MW units in Guang’an Power Plant in high sulfur coal area, the influence of the WESP secondary current and secondary voltage on the removal rate of SO3 is analyzed,which provides reference for the promotion and application of WESP in other SO3removal areas.
