Gas turbine works with the use of many kinds of fuel to run a compressor. The compressor will bring the atmospheric air flows through its highest pressure and with the addition of fuel into the air it will ignite and then the combustion will generate a high-temperature flow.
A gas turbine is also known as the combustion turbine. It is a type of internal combustion engine, used in items like jets, and boats.
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
The gas (working fluid) having flown through the turbine does some work on the turbine, converting its thermal energy into mechanical work produced by the turbine and coming out as an expanding gas with lower temperature and pressure.

Basically, a gas turbine is powered by gas under pressure, The gas is pressurized by burning some type of fuel such as kerosene, jet fuel, or propane. That heat causes air expansion, and the subsequent inflow of air makes the turbine spin. A gas turbine consists of three main parts; a combustion chamber, a turbine and a compressor. Air and fuel are mixed in the combustion chamber where it is ignited and increases in speed and power. This power is directed over the turbine blades which spin the turbine and power the compressor. It's a pretty simple process: heated fuel causes pressure and air expansion. The expanded air causes a turbine to spin. That is how gas turbines like jet engines work.
As the surrounding/ambient temperature increases, the temp of air entering the air compressor increases which means that the it's specific volume of air increases. Since the work of compressor = delta pressure x specific volume of air, then as the specific volume of air increases the work input of compressor increases and this is a problem because the total out put power of the turbine = work of the turbine - work of the compressor, so as the work of compressor increases, the total out put work of the gas turbine decreases. And that's why the efficiency of gas turbine is better in winter than in summer.
A gas turbine is one type of power plant. It produces power by burning gas to turn the turbine.
1.Turbine output is increased for same compressor work. 2.As more heat is supplied,thermal efficiency decreases.
Gas Turbine Research Establishment was created in 1959.
because all gas turbine has three stage buckets
The function of IGV in a gas turbine is to prevent surges and stall conditions.
The first gas turbine in the Gulf started working in the 1970s
Gas turbine power generators are used in two basic configurations. Simple Systems consisting of the gas turbine driving an electrical power generator. You fill them with gas carefully & turn them in.
