Any hydrocarbon fuel from high octane gasoline to heavy diesel oil can be used efficiently. The hot gas coming out from the combustion chamber is then passed to the turbine where it expands doing mechanical work. Less floor space is required for its installation. The gas turbine is the most satisfactory power developing unit among various means of producing mechanical power due to its exceptional reliability, freedom from vibration, and ability to produce large powers from units of comparatively small size and weights. Ignition causes the gases to expand and to rush first through the turbine and then through a nozzle at the rear. The impeller provides high kinetic energy to the air and the diffuser converts kinetic energy into pressure energy. Combustion is begun by an electric spark and once the fuel starts burning the flame is need to stabilize. A gas turbine, also called a combustion turbine, is a type of continuous and internal combustion engine.The main elements common to all gas turbine engines are: an upstream rotating gas compressor; a combustor; a downstream turbine on the same shaft as the compressor. Secondary air must be received at right points in the CC, otherwise, the cold injected air may cool the flame thus reducing the rate of reaction. It is the ratio of the enthalpy drop in the moving blades to the enthalpy drop in the stage. The remaining 50 per cent of air is mixed with burnt gases in the tertiary zone to cool the gases down to the temperature suited to the turbine blade materials. Vibrations (axial and radial) and speeds, both at the air compressor and Gas turbine should be continuously taken into consideration.
