Exergy Analysis of Raipur Thermal Power Plant in Raipur (India); A Case Study

In this paper, the exergy analysis of “(56MW) thermal power plant Raipur (India); a case study” are presented. The main objectives of this paper are to analyze the plant’s component separately and to identify the parts having largest exergy losses. This paper will also justify the major sources of losses and exergy destruction in the power plant. According to the study, percentage ratio of the exergy destruction to the total exergy destruction was found to be maximum in the boiler system (57 %) followed by the turbine (33.3%), and then the condenser (5.34%). the exergy efficiency of the power plant was 31.12%. Which are low compared to modern power plants. According to analysis found that boiler is the major source of irreversibility in the power plant, but exergy destruction rate in boiler can be reduced by reheating the system. It is a suitable technique for decrease boiler’s irreversibility. How reheating is the best tool for improvement of overall performance and comparison to the real condition of power plant is also presented in this paper. Without any change of fuel consumption, how reheating minimized exergy destruction, has also be investigated.
