Brayton cycle gas turbine - has combustion chamber and turbine with hot-cool operating cycle

摘要

The constant pressure, Brayton cycle gas turbine includes a combustion chamber and a turbine uses a hot- cool operating cycle with a hot phase alternating with cool phase. Gas is continuously fed to the combustion chamber and from the combustion chamber to the turbine. During the hot phase all of the gas fed to the turbine is hot. The gas temperature during the hot phase is higher than the turbine could withstand in a continuous burn mode. The time of the hot phase is less than the time it would take for the turbine blades to "soak" to the high temperature of the hot gas.
