A turbine which extracts energy from the hot moving gas and converts it into electricity, is called gas turbine.
Types Of Gas Turbine
1. According to the Path of Working Substance
(i) Closed Cycle Gas Turbine: In closed cycle gas turbine the, the air (gas) is continuously circulates within the turbine.
(ii) Open Cycle Gas Turbine: In this types of turbine, the air is not circulates continuously within the turbine. The air after flowing over the blades of the turbine exhausted in the atmosphere.
(iii) Semi-Closed Gas Turbine: As the name indicates, the semi-closed gas turbine is the combination of both the turbines, one working on the open cycle and the other on the closed cycle.
2. According to the Process of Heat Absorption
(i) Constant Pressure Gas Turbine: A turbine in which the air is heated at constant pressure in the combustion chamber is called constant pressure gas turbine.
(ii) Constant Volume Gas Turbine: A turbine in which the air is heated at constant volume in the combustion chamber is called constant volume gas turbine.
A turbine which extracts energy from the fast moving wind and converts it into electricity, is called wind turbine
