ABSTRACT:
An industrial gas turbine engine capable of operating at higher temperatures than air cooled nickel based alloy airfoils in the turbine. The engine burns stoichiometric or rich to produce a hot gas stream that is mostly without oxygen, and the turbine airfoils are made from a high temperature resistant material such as a refractory material that also has poor oxidation resistance. A second small gas turbine engine is used to compress nitrogen gas that is used to pass through the turbine airfoils for cooling where the film cooling nitrogen gas is injected into the hot gas stream but without igniting the fuel rich gas stream.
