Gas turbine efficiency is quite low this is because most of the energy generated to drive the compressor to generate compressed air. Besides being the amount of energy is wasted along with exhaust gas reflected by the high temperature exhaust gas. Thermal efficiency is directly proportional to the load are given, the greater the power plant means burdened with the higher thermal efficiency. Like wise isentropic efficiency of the compressor, turbine and combustion chamber efficiency. Attempts to get a more optimal thermal efficiency it needs some effort to optimize the loading of them, keeping the isentropic efficiency of the compressor, turbine and combustion chamber. To reuse wasted energy in conjunction with waste gas is by utilizing a regenerative system. With the regenerative system, the compressed air coming out of the compressor preheated by the exhaust gas heat, so as to achieve the same turbine inlet temperature requires low heat. With fuel thereby improving thermal efficiency of the gas turbine.} }
