Abstract
A system includes a turbine combustor that includes a head end portion having a head end chamber, a combustion portion having a combustion chamber disposed downstream from the head end chamber, a cap disposed between the head end chamber and the combustion chamber, and a flow distributor configured to distribute an exhaust flow circumferentially around the head end chamber. The flow distributor includes at least one exhaust gas flow path.
Claims15
A system, comprising:
- a turbine combustor, comprising:
- a head end portion having a head end chamber;
- a combustion portion having a combustion chamber disposed downstream from the head end chamber;
- a cap disposed between the head end chamber and the combustion chamber;
- and
- a flow distributor assembly comprising a plurality of flow distributors, including a first flow distributor and a second flow distributor, spaced circumferentially around the head end portion, wherein a first portion of a recirculated exhaust gas flow flows through a first space of one or more spaces circumferentially adjacent to the first flow distributor to a mixing region in the head end portion, the recirculated exhaust gas flow comprising recirculated combustion products;
- wherein the first flow distributor comprises a first exhaust gas flow path configured to receive a second portion of the recirculated exhaust gas flow and to route the second portion of the recirculated exhaust gas flow radially inward to a cooling region in the head end portion adjacent the cap, upstream of the combustion chamber;
- wherein the second flow distributor comprises a second exhaust gas flow path configured to receive a third portion of the recirculated exhaust gas flow and to route the third portion of the recirculated exhaust gas flow radially outward to extract the third portion of the recirculated exhaust gas flow from the turbine combustor;
- and wherein the first space is circumferentially adjacent to and between the first flow distributor and the second flow distributor.
6 more elements
A system, comprising:
- an oxidant compressor;
- and a gas turbine engine, comprising:
- a combustor section having a turbine combustor, wherein the turbine combustor comprises a cap disposed between a head end chamber and a combustion chamber;
- a turbine driven by combustion products from the turbine combustor;
- an exhaust gas compressor driven by the turbine, wherein the exhaust gas compressor is configured to compress and route an exhaust flow to the turbine combustor, wherein the exhaust flow comprises recirculated combustion products, and the oxidant compressor is configured to compress and route an oxidant flow to the turbine combustor;
- an exhaust extraction port coupled to the combustor section;
- and a flow distributor assembly comprising a plurality of flow distributors, including a first flow distributor and a second flow distributor, spaced circumferentially around the head end chamber, wherein a first portion of a recirculated exhaust gas flow flows through a first space of one or more spaces circumferentially adjacent to the first flow distributor to a mixing region in the head end chamber, the recirculated exhaust gas flow comprising recirculated combustion products;
- wherein the first flow distributor comprises a first exhaust gas flow path configured to receive a second portion of the recirculated exhaust gas flow and to route the second portion of the recirculated exhaust gas flow radially inward to a cooling region in the head end chamber adjacent the cap, upstream of the combustion chamber;
- wherein the second flow distributor comprises a second exhaust gas flow path configured to receive a third portion of the recirculated exhaust gas flow and to route the third portion of the recirculated exhaust gas flow radially outward to extract the third portion of the recirculated exhaust gas flow from the turbine combustor;
- and wherein the first space is circumferentially adjacent to and between the first flow distributor and the second flow distributor.
