20120247118 | COMBUSTOR CROSSFIRE TUBE - The present application and the resultant patent provide a combustor for mixing a flow of air and a flow of fuel. The combustor may include an air path for the flow of air, a number of fuel injectors positioned in the air path for the flow of fuel, and a crossfire tube positioned within the air path upstream of the fuel injectors. The crossfire tube may include a number of purge holes positioned on a downstream side thereof to reduce a wake in the flow of air caused by the crossfire tube in the air path. | 10-04-2012 |
20120297785 | SYSTEM AND METHOD FOR FLOW CONTROL IN GAS TURBINE ENGINE - A system includes a gas turbine combustor, which includes a combustion liner disposed about a combustion region, a flow sleeve disposed about the combustion liner, an air passage between the combustion liner and the flow sleeve, and a structure between the combustion liner and the flow sleeve. The structure obstructs an airflow through the air passage. The gas turbine combustor also includes a wake reducer disposed adjacent the structure. The wake reducer directs a flow into a wake region downstream of the structure. | 11-29-2012 |
20130042619 | COMBUSTOR RESONATOR - Certain embodiments of the present disclosure include a combustor resonator having a non-uniform annulus between a combustor assembly and a resonator shell. The combustor resonator may further include resonator necks or passages having non-uniform lengths and geometries. | 02-21-2013 |
20130074505 | SYSTEM FOR DIRECTING AIRFLOW INTO A COMBUSTOR - A system includes a gas turbine combustor. The gas turbine combustor includes a combustion liner disposed about a combustion region and a sleeve disposed about the combustion liner. The combustion liner and the sleeve define an airflow passage circumferentially about the liner. The gas turbine combustor also includes multiple axial injectors configured to direct an airflow into the airflow passage in an axial direction facilitating a momentum exchange between an injection flow and a crossflow from an upstream portion of the combustor. The multiple axial injectors are asymmetrically configured to provide an uniform injection of the airflow circumferentially about an axis of the gas turbine combustor. | 03-28-2013 |
20140182301 | SYSTEM AND METHOD FOR A TURBINE COMBUSTOR - 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 separator configured to separate a first exhaust flow from an oxidant flow. The flow separator is configured to direct the first exhaust flow into the head end chamber. The turbine combustor also includes a mixing region configured to mix the first exhaust flow with the oxidant flow to provide an oxidant-exhaust mixture. | 07-03-2014 |
20140182302 | SYSTEM AND METHOD FOR A TURBINE COMBUSTOR - 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 at least one of an exhaust flow, an oxidant flow, an oxidant-exhaust mixture, or any combination thereof circumferentially around the head end chamber. | 07-03-2014 |
20140182303 | SYSTEM AND METHOD FOR A TURBINE COMBUSTOR - 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. | 07-03-2014 |
20140182304 | SYSTEM AND METHOD FOR A TURBINE COMBUSTOR - 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 oxidant flow circumferentially around the head end chamber. The flow distributor includes at least one oxidant flow path. | 07-03-2014 |
20140182305 | SYSTEM AND METHOD FOR A TURBINE COMBUSTOR - 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, a mixing region configured to mix an exhaust flow with an oxidant flow to provide an oxidant-exhaust mixture, and a flow distributor configured to distribute the oxidant-exhaust mixture circumferentially around the head end chamber. The flow distributor includes at least one oxidant-exhaust mixture path. | 07-03-2014 |
