Abstract
High power density and operational flexibility make gas turbines an indispensable part of contemporary energy conversion systems. However, in the simple cycle configuration, the thermal efficiency is generally low because the exhaust heat loss is large and the compression work is high. The current investigation is focused on enhancing the thermal efficiency of a gas turbine by the introduction of two augmentation schemes, namely a recuperator and an intercooler. A numerical and thermal simulation study was carried out to model the gas turbine cycle based on the first and second laws of thermodynamics. Simplicity and Modified cycles Performance of simple and modified cycle are investigated. The results showed that the recuperator raised the thermal efficiency of the overall system by about 6–10%, and the compressor work was alleviated by the intercooling system by about 12%. A maximum improvement of about 15% for the overall efficiency was obtained from the application of both schemes simultaneously when compared to the simple cycle. The results verify that the parallel use of a recuperator and intercooler is a feasible and attractive alternative for increasing the energy output of a gas turbine. The integration process will be very valuable for application in Iraqi gas power plants to enhance fuel economy and sustainable energy generation.
