Abstract

Abstract: The thermal performance is the key affecting factor for the design of the cooling tower. In order to obtain the thermal performance of the large seawater cooling tower, the experimental research is conducted on the thermal performance of the large seawater cooling tower with 12 000-m2 drenching area used in a 1 000-MW power unit. From the research the thermal performance equation of the tower is obtained and the comparison is conducted between the tower’s thermal performance and the test results of the packing in the freshwater simulated cooling tower. The real air temperature distribution in the large seawater cooling tower is presented. The influence of seawater on the outlet water temperature of the cooling tower is analyzed quantitatively. The results can be a reference for the engineering application of the seawater cooling tower.

Key words: thermal power unit, seawater cooling tower, thermal performance, air temperature distribution, outlet water temperature
