Gas turbine
A gas turbine is a turbine thermal enthalpy drop using a gas or gas mixture to produce by means of blades that rotate around an axis of a quantity of mechanical energy available at the turbine coupling. Gas turbine is also known as the gas turbine installation (GTI).
From a thermodynamic point of view of gas turbine engine works very similar to a car. Atmospheric air is admitted in a compressor blade, where it is compressed, following the introduction of a fuel’s ignition and combustion in a combustion chamber. Loosen the flue gas in a turbine to extract from them the work and then are discharged into the atmosphere. The process is continuous and runs only plays a rocking motion, which for a given power leads to a lower total mass of the system. As a result, gas turbines have been developed especially for aviation engines, but find applications in many other areas, one of the most modern combined-cycle power plants as steam-gas.
The simplest gas turbine consists of a compressor which is mounted on the same shaft with a turbine. Compressor air absorbs from the atmosphere and compresses it to a pressure of several bars. Compressed air reaches a combustion chamber where fuel is introduced. This takes place at constant pressure combustion, the temperature rises and the volume of the combustion gases. Loosen the flue gas turbine producing mechanical work, and then discharged into the atmosphere.
