Improvement of Low Performance Condensates in Thermal Power Plants: Case Study

Abstract

More than 60% decreasesin the generating capacity of most electricity generating units has been observed in recent times. This reduction in the performance of steam power plants is higher for part and full load operations. Therefore, in this study, the performance evaluation and calculation methodology of the condenser of steam power plantsarepresented. The best condenser pressure which can be achieved in ideal operation conditions has been evaluated by real time parameters. Condenser performance study was carried out with respect to the steam flow rate, condenser pressure, and make up water. The result show that increasing the fouling thickness to 3 mm led to increase condenser pressure to 30kPa at the plant full load. A combination of the data acquired of the steam condenser from the simulator, actual measurement, and the existing literature suggests the accuracy of the proposed equations.
