The Exhaust-Heated Gas-Turbine Cycle

The author describes and discusses a gas-turbine cycle in which the combustion chamber is placed behind the turbine, raising the exhaust temperature to a level at which all the heat required for the compressor air can be supplied by the heat exchanger. The possibilities of such a cycle for the utilization of low-grade solid or liquid fuels are explained and attention is drawn to the convenience with which steam can be generated from the otherwise wasted heat, and the over-all thermal efficiencies which may be obtained by a combination of gas and steam turbines.
