Abstract:

The spacing distance between two parallel mechanical ventilating cooling tower rows was designed too large according to the relevant Chinese Design Codes in the Indonesian 4×600MW Thermal Power Plant. A mathematical model experiment was made to analyze the influence of local practical environment factor and spacing distance of tower row on cooling effort, evaluate the environmental wind’s influence on reflux and disturbance of exhaust wet air in different cooling tower row layouts, and optimize the cooling tower row layout. It was concluded that as its long axis parallels the  dominate summer wind direction, the spacing distance has no influence on wet air reflux and spacing distance can be decreased from 51m to 21.6m, and thereby the site area of the plant is reduced with guaranteed cooling effort.
 

Key words: mechanical ventilating cooling tower, cooling tower row layout, environmental wind, cooling effort
