Abstract
A system includes a gas turbine engine that includes a turbine section having one or more turbine stages between an upstream end and a downstream end, an exhaust section disposed downstream from the downstream end of the turbine section, and a fluid supply system coupled to the exhaust section. The fluid supply system is configured to route an inert gas to the exhaust section.
Claims20
A system, comprising:
- a gas turbine engine, comprising:
- a turbine section having one or more turbine stages between an upstream end and a downstream end;
- an exhaust section disposed downstream from the downstream end of the turbine section;
- and
- a fluid supply system coupled to the exhaust section, wherein the fluid supply system is configured to route an inert gas to the exhaust section.
2 more elements
A method, comprising:
- combusting a fuel with an oxidant and an exhaust gas in a combustion portion of a turbine combustor to generate combustion products;
- driving a turbine with the combustion products from the turbine combustor;
- expanding and cooling the combustion products from the turbine through an exhaust passage in an exhaust section;
- and
- routing an inert gas from a fluid supply system to the exhaust section.
2 more elements
A system, comprising:
- a turbine exhaust section configured to mount downstream from a turbine section of a gas turbine engine, wherein the turbine exhaust section comprises an exhaust passage configured to receive exhaust from the turbine section, and an inert gas passage extending through a structure of the turbine exhaust section;
- and
- a fluid supply system coupled to the exhaust section, wherein the fluid supply system is configured to route an inert gas to the inert gas passage in the exhaust section.
