Abstract:
A power generation system capable of eliminating NOxcomponents in the exhaust gas by using a 3-way catalyst, comprising a gas compressor to increase the pressure of ambient air fed to the system; a combustor capable of oxidizing a mixture of fuel and compressed air to generate an expanded, high temperature exhaust gas; a turbine that uses the force of the high temperature gas; an exhaust gas recycle (EGR) stream back to the combustor; a 3-way catalytic reactor downstream of the gas turbine engine outlet which treats the exhaust gas stream to remove substantially all of the NOx components; a heat recovery steam generator (HRSG); an EGR compressor feeding gas to the combustor and turbine; and an electrical generator.
Abstract:
An integrated plate is provided for use with a combustor including a casing, a fuel plenum extending circumferentially about the casing, and a fuel nozzle extending axially through the casing. The integrated plate includes a plurality of fuel injection pegs that extend radially between the fuel plenum and the fuel nozzle.
Abstract:
An aft frame of a turbine engine transition piece body is provided and includes an annular body disposed within a first annular space defined between an impingement sleeve and a compressor discharge casing and aft of a second annular space defined between the transition piece body and the impingement sleeve and including a main portion with a first surface facing the first annular space and a second surface facing the forward annular space. The main portion has an impingement hole extending therethrough from an inlet at the first surface of the annular body to an outlet at the second surface of the annular body to define a fluid path along which the first and second annular spaces communicate with one another.
Abstract:
A combustor includes an end cap. The end cap includes a first surface and a second surface downstream from the first surface, a shroud that circumferentially surrounds at least a portion of the first and second surfaces, a plate that extends radially within the shroud, a plurality of tubes that extend through the plate and the first and second surfaces, and a first purge port that extends through one or more of the plurality of tubes, wherein the purge port is axially aligned with the plate.
Abstract:
A system comprises a turbine combustor cap. The turbine combustor cap includes a plurality of segments. Each segment of the plurality of segments has edges abutting at least two fuel nozzle receptacles. Moreover, each segment of the plurality of segments does not completely surrounding any one fuel nozzle receptacle.
Abstract:
A nozzle includes a center body and a shroud surrounding the center body to define an annular passage. An arcuate annular guide extending from a point radially inward of the shroud to a point radially outward of the shroud defines a first airflow between the arcuate annular guide and the shroud and a second airflow between the arcuate annular guide and the center body.
Abstract:
A system includes a turbine fuel nozzle assembly. The turbine fuel nozzle assembly includes a first fuel nozzle including a first air inlet and a second fuel nozzle including a second air inlet. The turbine fuel nozzle assembly also includes a first inlet flow conditioner disposed adjacent the first air inlet of the first fuel nozzle, wherein the first air inlet flow conditioner extends only partially around the first fuel nozzle. The turbine fuel nozzle further includes a second inlet flow conditioner disposed adjacent the second air inlet of the second fuel nozzle, wherein the second air inlet flow conditioner extends only partially around the second fuel nozzle, and the second inlet flow conditioner is separate from the first inlet flow conditioner.
Abstract:
A gas turbine engine combustor is provided and includes an array of fuel nozzles, a combustion casing assembly disposed about the array of fuel nozzles and an end cap assembly disposed within the combustion casing assembly to define with the combustion casing assembly an axis-symmetric annulus through which fluid travels into each of the fuel nozzles, at least one of the combustion casing assembly and the end cap assembly being formed with lobed, three-dimensional contouring.
Abstract:
A system includes an air flow conditioner configured to mount in an air chamber separated from a combustion chamber of a turbine combustor. The air flow conditioner comprises a perforated annular wall configured to direct an air flow in both an axial direction and a radial direction relative to an axis of the turbine combustor. In addition, the air flow conditioner is configured to uniformly supply the air flow into air inlets of one or more fuel nozzles.
