Numerical analysis of performance of cooling towers

摘要

Cooling towers (CT), as apart of thermal power plants, have a major importance from the thermodynamic point of view. They represent a necessary part of a thermo-energetic facility needed to cool down the cooling water from the condenser, which cools the steam coming from the turbine thus closing the thermodynamic cycle. One of the basic parameters involved in evaluation of the performance of a cooling tower is the so-called number of transfer units (NTU). In this paper, the performance of cooling towers operating as apart of Units 5 and 6 in the Thermal Power Plant Kakanj (TPPK) in Bosnia and Herzegovina will be analyzed. For the purpose of the numerical evaluation of the NTU value, real data are taken from the TPPK. Based on the obtained results, suggestions will be given for improvement of the cooling towers performance.
