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.
Claims18
A method for stabilizing a refractory carbide hot gas path component comprising:
- combusting a fuel in a combustor;
- 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 at least a portion of the hot gas path component comprises refractory carbide.
1 more element
A turbine power generation system, comprising:
- a plurality of hot gas path components comprising a combustor and a turbine, said combustor configured to combust a mixture of air with a fuel to produce an exhaust gas stream, and said turbine configured to convert energy of said exhaust stream into useful mechanical energy;
- and
- wherein said plurality of hot gas path components is thermally coupled to a hot gas path;
- and
- a first conduit configured to deliver a high carbon activity gas to at least one hot gas path component of said plurality of hot gas path components;
- wherein a refractory carbide comprises at least a portion of said plurality of hot gas path components.
3 more elements
A cooling system for a hot gas path component, said system comprising:
- a hot gas path component;
- and
- a first conduit configured to deliver a high carbon activity gas to said hot gas path component,
- wherein said high carbon activity gas forms a film of cover gas on a surface of said hot gas path component.
