PERFORMANCE OF A RICH COMBUSTION REFRACTORY METAL COMBINED CYCLE POWER PLANT
A new concept in gas turbine engines is presented in which multiple stages of combustion and refractory metal alloys are used to obtain high turbine inlet temperatures. The oxidizing environment present in conventional engine combustors and turbines is eliminated by utilizing fuel-rich combustion for the first combustor, thus providing a reducing environment for the refractory metal alloy turbine blades. The products of combustion from the first stage of combustion are subsequently burned in a second combustor which can be part of a conventional gas turbine engine or a steam power plant furnace. The results of a feasibility study of the concept are presented. Overall system thermal efficiencies in excess of 50% are shown to be attainable with molybdenum alloys available today.
