Abstract
Abstract A composite gas turbine set comprising a large main gas turbine set and a small auxiliary gas turbine set disposed in parallel arrangement for the production of regenerative cycles. A portion of the gas issued from a compressor of the main gas turbine set is applied to a compressor of the auxiliary gas turbine set. The exhaust gas which has provided regeneration in the auxiliary gas turbine set is applied to the turbine of the main gas turbine set. The composite turbine set is arranged so as to minimize increases in fuel consumption under widely variable load conditions.
