Theoretical study for the effect of different fuels on the perfomance of open gas turbine power plant

الملخص EN

The use of gas turbine is increasing day by day for producing electricity and for various industrial applications.

It’s well-known that thermal efficiency of open gas turbine varies with the fuel used in the combustion process.

In this work an investigation for the effect of different hydrocarbon, alcohol and hydrogen fuels on the performance of simple and modified gas turbine has been studied.

A computer program was written in Quick basic Language has been accomplished to calculate the thermal efficiency, work ratio, specific fuel consumption….etc.

in gas turbine working with different types of fuels.

It’s found that specific fuel consumption is margined according to the fuel used because its dependency on the enthalpy of reaction of the fuel.

Also it’s noted that hydrogen fuel has higher thermal efficiency and lower fuel consumption than other fuels, but its requires high pressure to insert it to combustor.

Therefore we must use methane as fuel in the plant since it is more common type than other.
