Abstract
A closed cycle recuperator microturbine and an open cycle heat generating system for supplying heat for driving the turbine includes a pair of valves fluidly connected to the compressor inlet and compressor outlet for bleeding air therefrom when the microturbine engine is operating in the lower power operating envelope of the operating conditions of the microturbine engine while the open cycle heat generating system maintains the thermodynamic conditions of the microturbine engine operating substantially a constant value whereby the fuel consumption of the microturbine engine is enhanced during the low power conditions. The microturbine engine serves to power an electric generator and a ECU heater.
