The continual need to optimize costs and the recent competitive pressure from renewables have seen renewed focus on improving and optimizing plant components’ efficiency. Combined cycle power plants are better from thermal efficiency point of view compared with coal-based power plants. Exergy analysis offers better alternative to energetic analysis based on simpler model of energy balance only. Identifying system energy losses is easier using exergy analysis, making it a better analytical tool. The paper presents a case study of exergy analysis of Gautami combined cycle power plant. Component level theoretical analysis is done first and applied to the operational data from the plant. The results showed that the gas turbine combustion chamber has the highest exergy loss of 33%. Impact factors like ambient temperature, pressure ratio, turbine inlet temperature and heat recovery steam boiler are also considered on the exergy losses of the power plant.
Increasing use of energy has meant an increasing need for its use in a more efficient
manner. The need for better and more efficient use of any resource is obligatory
upon any society or organization.
This pressure is always more on the incumbent power plants as the newer
installations are always more efficient coming in with improved technologies. This
continual need to optimize costs got further impetus with the recent competitive
pressure from the renewables sector. As a result, there is a heightened focus on
improving and optimizing plant components’ efficiency. From thermal efficiency
point of view, the combined cycle power plants are better compared with coal-based
power plants.
