[Purposes]This study aims to investigate the hydraulic calculation of water distribution in power plant cooling towers to optimize their operational efficiency and improve water resource utilization.[Methods]To achieve the research objectives,a hydraulic calculation model for water distribution was developed,and reasonable distribution schemes were designed based on this model.During the model es⁃tablishment,various influencing factors were considered,including the structural characteristics of the cooling tower,the type and layout of spray nozzles,the inlet water temperature,and the outlet flow rate,ensuring the model accurately reflects actual operational conditions.Different schemes were then de⁃signed and optimized to achieve optimal hydraulic distribution.[Findings]The results show that the uni⁃formity coefficients of all 15 tested spray nozzle designs did not exceed the upper limit.The optimal design scheme was determined to be a nozzle diameter of 34 mm for the inner zone and 40 mm for the outer zone.[Conclusions]The study concludes that proper hydraulic calculations for cooling tower water distri⁃bution not only enhance overall efficiency but also contribute to water conservation and reduced energy consumption.This has a positive impact on the economic performance of power plants and promotes envi⁃ronmental sustainability.As the power industry increasingly emphasizes environmental protection and energy efficiency,optimizing water distribution schemes in cooling towers will become a key focus for fu⁃ture research,providing more scientific and rational solutions for power generation.
