摘要：
Numerous factors can affect the operating performances and the design of the indirect air cooling system of power plant. The present study developes physico-mathematical model to describe the thermo-flow characteristics of air cooling tower for indirect air cooling system. Based on the model, a comprehensive analysis on optimization of air cooling tower is conducted for 600MW indirect air-cooled power generating unit. By using the software VC++, the indirect air-cooled tower optimization program is developed. With the help of optimization of tower structure, a tower with better structure is used to conduct thermal analysis of the influences of ambient temperature, wind speed, and saturated exhaust flow rate on back pressure of turbine. The present study may be of great value on optimization design and safe operation of large-scale indirect air-cooled power plant. (C) 2014 The Authors. Published by Elsevier Ltd.
