ENERGY SAVING AND ENVIRONMENTAL PROTECTION AT RECIRCULATING COOLING WATER SYSTEMS

Abstract

This paper deals with the problems of energy saving and environmental aspects (water consumption, drift emission, noise level) of cooling systems using mechanical draft wet cooling towers. Graphs have been developed to represent correlation between cooling performance, size of cooling towers, and fan power requirement for the most common operating range. Tracing of distinct cold water temperature is shown, below which reduction of fan power is advisable. Generalized charts are presented to provide values on cooling tower evaporation loss and make-up water demand.
