Efficiency Improvement Methods of Gas Turbine

Abstract

Gas turbines are machines that work directly with ambient air, then anything that causes a change in the inlet air condition, effect on turbine efficiency. Relative humidity, Mean sea level and environment temperature have a direct effect on gas turbine efficiency. Generally, peak demand for electricity occurs during the summer time, that the output power of the gas turbine reaches its minimum value for high temperature of inlet air. This makes a lot of pressure on the power industry and to compensate for excess demand, there will always be a need for further investment of new plants. Research done on V94.2 turbines manufactured by Siemens and for pilot studies, thermo flow and GT Pro software was used.
