Abstract
Oxygen vapor at elevated pressures is utilized as the oxidant component of an oxidant-fuel mixture in a fuel burning system for generating combustion gases which are then mixed with ambient gas and exhaust gases for driving a turbine wheel of a gas turbine operating in a burn-cool cycle. The oxygen vapor is provided from liquid oxygen which preferably is vaporized by heat exchange with hot exhaust gases from the turbine. The burn-cool system of turbine operation permits the oxygen vapors to be supplied to the burner of a combustion chamber at high inlet pressures of about 1500 psia, in contrast ot prior art systems which provide low pressure oxygen to a chamber for combustion in automobile or turbine engines.
