Effect of Fuel Types on the Performance of Gas Turbines

In this paper we investigate the effect of the different types of fuels used during the same period in order to see how the efficiencies were affected. There are two types of fuels which can be used in the power plant station under consideration, one of them is liquefied petroleum gas (LPG) and the other is the light diesel oil (LDO). The efficiency of the plant is high while using liquefied petroleum gas (LPG) when compared to light diesel oil (LDO). This due to two reasons , the first is the high low heat value (LHV) of LPG , The second is the mixture of LPG and the air is more homogenous than LDO mixture during the combustion process.
