Abstract:

With the increasingly strict national environmentprotection policy, the ultralow emission transformation of coalfired units has been completed. After the ultralow emission transformation of No.6 unit (330MW) in Huadian Zibo Thermal Power Company Limited, a series of problems occurred in the design, construction and material selection, resulting in unstable operation of the wet electrostatic precipitator(WESP),low reliability of water system operation and risks in exceeding the environmentprotection standard. In response to the existing problems, solutions such as renovating the spray pipe, optimizing the filter program, and accurate measuring of the indicator are proposed. After implementation of the scheme, the operational reliability of the WESP water system in No.6 unit can be improved, and the experience of ultralow emission transformation of coalfired units are provided.
