Datang Wu’an Power Plant indirect circulating cooling water pump retrofit project | Handan, Hebei

Application scenario: Surface condenser indirect air-cooling circulating water system of Datang Wu’an Power Generation Co., Ltd. The original pump hydraulic model was outdated with poor operating condition matching, long-term “large motor driving small load” operation, high valve throttling losses, and high auxiliary power consumption.


Solution content: M&W ENERGY SAVING completed the full process from survey to delivery within one month—CFD independent modeling to customize hydraulic model, upgrading single-speed pump to dual-speed pump for variable load operation, redesigning upper and lower pump casings to improve wear resistance; modular standardized design compressed the construction period, with on-site sectional component replacement enabling non-stop installation.


Project results: Verified the “large-scale manufacturing + customized design” model, responding to single-plant customization needs with batch production cost and delivery speed, providing a replicable benchmark for energy-saving retrofit of thermal power indirect circulating cooling water pumps.
