Summary

Fouling of cooling tower fills is one of the most important factors affecting its thermal performance, which reduces cooling tower effectiveness and capability with time. In this paper, the fouling model presented in an earlier paper using the experimental data on fill fouling, is used to investigate the risk-based thermal performance of the cooling tower. It was demonstrated that the effectiveness of the cooling tower degrades significantly with time indicating that for a low risk level (p= 0.01), there is a roughly 6.0% decrease in effectiveness for the given fouling model. The sensitivity analysis of the cooling tower was investigated for both rating and design calculation for different values of mass flow rate ratios. The effect of atmospheric pressure on the thermal performance of the cooling tower is also demonstrated.
