Abstract

Efficiency of a gas turbine is closely related to the intake air temperature. An increase in the intake air temperature will results in a decreasing of the turbine efficiency. This report basically discusses the results from the research done and basic understanding of the chosen topic, which is design of a heat exchanger for gas turbine inlet air cooling system. The project aims at providing a constant air temperature at the inlet side of the gas turbine irrespective of the change in ambient temperature by employment of a heat exchanger to reduce the temperature at constant low temperature. In this paper, focus is given to the best fin geometry for plate and fin heat exchanger in order to improve the efficiency of the gas turbine. This paper also discussed about the selection of a few parameters based on given standard rating in designing high performance plate and fin heat exchanger with high transfer rate of heat and a few numerical solution to find the suitable sizing of heat exchanger for gas turbine at Gas District Cooling area. A clear methodology to complete this project was also proposed in this paper. As a result from this research, it was said to achieve the objectives made with satisfied parameters that can be applied to the real world problem to reduce the air temperature. The results were done with the helped of assumptions made and with set of analytical equations to identify the parameters desired. Fin surface geometry of 1/8 - 16.00 (D) can be use for air side while as for the water side, geometry of 1/8-19.82 (D) can be use. Both of the fin surface geometry was tested and proved to reduce the air and water temperature and yield a satisfied heat transfer coefficient, as well as efficiency.
