No earlier wear of the turbine blades, because the enclosed gas does not gets contaminated while flowing through the heating chamber, Earlier wear of turbine blades, as the air from the atmosphere enters the combustion chamber it gets contaminated. Here only air can be used as the working fluid. Any other fluid that possesses better thermodynamic properties like helium can be used. The working fluid is replaced continuously. The working fluid is circulated continuously. In an open cycle, the gases coming out from the gas turbine is exhausted in the atmosphere. In closed cycle gas turbine, the gas that comes out from the gas turbine passes into the cooling chamber. So the products of combustion gets mixed with the heated air and hence the amount of gas does not remain the same. Here the compressed air is heated in the combustion chamber. As the air is heated by an external source, so the amount of the gas remains the same.
In this, first the air is compressed in the compressor and then heated in a heating chamber. air is replaced again and again while flowing through the gas turbine.Ĭlosed Cycle Gas Turbine Vs Open Cycle Gas Turbine In the closed cycle gas turbine the same working fluid is circulated again and again within the turbine but in the open cycle gas turbine the working fluid i.e. The basic difference between them is the circulation of the working fluid.
The difference between closed cycle gas turbine and open cycle gas turbine can be done on the basis of source of heating, types of working fluid, circulation of air, wearing capacity of turbine blades, installation, maintenance cost and much more.
