Abstract
A turbine power generation system with enhanced stabilization of refractory carbides provided by hydrocarbon from high carbon activity gases is disclosed. The disclosure also includes a method of using high carbon activity gases to stabilize hot gas path components.
Claims10
A method for stabilizing a refractory carbide hot gas path component comprising:
- combusting a fuel in a combustor to form a gas stream comprising post-combustion gases;
- and
- delivering a high carbon activity gas to at least a portion of a hot gas path component thermally coupled to a hot gas path, wherein the component comprises a plurality of film holes disposed to cover at least a portion of the component with a layer of gas, and wherein delivering the high carbon activity gas comprises introducing the high carbon activity gas via the plurality of film holes;
- wherein at least a portion of the hot gas path component comprises refractory carbide.
