Energy an‎d exergy analysis of Shahid Kazemi Mobarakeh Steel Company combined cycle powerplant

مهندسي مكانيك

In recent years, the imbalance between electricity supply an‎d deman‎d has led to power outages in the residential sector an‎d widespread restrictions on industrial activities. This situation, together with limited public budgets an‎d insignificant private-sector participation in investment projects of the Ministry of Energy, has pro‎mp‎ted the thirteenth government to oblige large energy-intensive industries to construct new power plants in order to compensate for part of this imbalance. In this context, Mobarakeh Steel Company, as a leading industrial enterprise in addressing the aforementioned imbalance, has undertaken the construction of the Shahid Kazemi combined cycle power plant within the Mobarakeh Steel Complex. Therefore, in order to achieve the stated objectives an‎d maximize the utilization of fossil fuel resources, it is essential that the power plant efficiency does not significantly deviate from that of conventional combined cycle power plants. Moreover, process parameters must be controllable by operators in such a way that the plant efficiency remains within an acceptable range under varying climatic conditions. Accordingly, the present study employs energy an‎d exergy analyses of the power plant to determine the efficiency of different operational scenarios influenced by climatic conditions. In addition, it aims to identify locations of energy losses an‎d zones of exergy destruction within the power plant process cycle, where the potential of energy conversion into useful work an‎d electrical power is degraded. In accordance to the results of present research, condenser is the main source of energy lose with 462314 kw; also, the most exergy lose takes place in gas turbine with 496457 kw; moreover, the usage of duct burner an‎d evaporative cooling systems at the same time will lead to more power generation in summer.
