Calculation and influence analysis for outlet water temperature of natural draft cooling tower

Cooling tower outlet-water temperature concerns greatly economic and safety operation of unit. A calculation model of cooling tower outlet water temperature is discussed in the paper. The results are given in the paper. The difference between calculated value and measured value is very little. The factors, which concern the inlet and outlet water temperature of cooling tower, are analyzed from the view of cooling tower and condenser influencing each other. The result indicates that the influence of all kinds of factors on inlet water temperature is greater than on outlet water temperature. It is helpful for cooling tower and condenser to calculate exactly in off-design condition.
