Abstract:

Nowadays, energy plays an important role in the economic and community development of country. Consequently, performance analysis of energy systems is one of the effective methods being used to prevent waste of energy resources. Among the different power generation technologies, steam power plants make a significant contribution to power generation in Iran, with a share of 47 % of electricity generation. Therefore, it seems that exergy analysis of the power plant can help designers to reduce energy losses and increase efficiency. In this study, energy and exergy analysis of a single-reheat steam power plant in Iran is presented. This analysis considered the effect of environment temperature variation on the energy and exergy efficiencies. The results showed that the condenser has most energy losses (50%) in a cycle, while maximum exergy destruction (84%) occurs in the boiler. The thermal and exergy efficiencies at reference temperature were computed as 36.84% and 34.75%, respectively. Exergy destruction and efficiency of each component have been considered and are reported in the paper. The effects of various parameters such as steam pressure, steam temperature and condenser pressure have also been examined in the cycle performance.

Performance of Derna Steam Power Plant at Varying Super-Heater Operating Conditions Based on Exergy

Abstract—In the current study, energy and exergy analysis of a 65 MW steam power plant was carried out. This study investigated the effect of variations of overall conductance of the super heater on the performance of an existing steam power plant located in Derna, Libya. The performance of the power plant was estimated by a mathematical modelling which considers the off-design operating condit...
