A SYSTEMATIC APPROACH IN POWER PLANT PERFORMANCE IMPROVEMENT THROUGH EXERGY ANALYSIS − A CASE STUDY OF TAMNAR, CHHATTISGARH, INDIA
摘要
A component-based energy and exergy evaluation was performed on a 600-MW thermal power plant located at Tamnar, Chhattisgarh, India. The main objectives of the current study are first and second law assessment of the power plant's main components and it was observed that the boiler is the main source of energy and exergy destruction followed by the condenser, turbine, and other components at full load conditions. The exergy−energy analysis was utilized for obtaining the exact magnitude of exergy destruction and efficiency in each component separately but for analysis of either major or trivial effects of environment condition variations on plant components. In the current investigations, it is observed that the plant is losing 1025.734 MW of total energy (including all the components) and 1261.413 MW of exergy destruction takes place. A high-pressure heater-5 is found to be the most efficient component with an efficiency of 99.83%. The energy and exergy efficiencies of the boiler are 73.42 and 39.69%, respectively. In the case of turbines, a high-pressure turbine is found to be more efficient as compared to the intermediate pressure turbine and low-pressure turbine. The energy efficiency of low-pressure heater-1, low-pressure heater-2, and low-pressure heater-3 was found to be 99.8, 89.37, and 99.79%, respectively. From the exergy analysis, the exergy efficiency of low-pressure heater-1, low-pressure heater-2, and low-pressure heater-3 was found to be 11.70, 77.70, and 80.6%, respectively. The deaerator is 97.01% efficient and the high-pressure heater-5 and high-pressure heater-6 are observed to have a higher efficiency of 99.83 and 92.02%, respectively. The energy and exergy efficiencies of the condensate extraction pump are found to be 99.48 and 9.56%, respectively.
