Abstract
In this work, the energy and exergy analysis of Tabriz power plant in Tabriz, Iran, is presented. The primary objectives of this paper are to analyze the system components separately and to identify and quantify the sites having largest energy and exergy losses at design mode at full load. It can be observed that although the heat loss in the condenser seems higher, the largest losses occur in the boiler, which has the highest exergy destruction. Also as long as the ambient temperature increases, the condenser pressure and heat loss also increase, resulting in reduced thermal efficiency. By reducing the temperature from 35 °C to −10 °C, plant thermal efficiency is increased by 1.38%.
