ABSTRACT:
A process for producing work comprises passing a combustion gas stream through a gas nozzle which directs the stream onto the rotatable blades of an expansion turbine. A fluid having a sonic velocity greater than the combustion gas is directed against and across the air-foil shaped vanes which form the nozzle at sonic velocity allowing the gas stream to accelerate to beyond Mach 1 without excessive loss of pressure. The fluid such as steam can be used to cool the vanes prior to entering the gas stream.
