Abstract: An injector for a gas turbine combustor including a catalyst coated surface forming a passage for feed gas flow and a channel for oxidant gas flow establishing an axial gas flow through a flow conditioner disposed at least partially within an inner wall of the injector. The flow conditioner includes a length with an interior passage opening into upstream and downstream ends for passage of the axial gas flow. An interior diameter of the interior passage smoothly reduces and then increases from upstream to downstream ends.

Abstract: A fuel injector and a combustor including a fuel injector that enables a combustor to burn a lean fuel/oxider gas mixture while providing low emissions of oxides of nitrogen (NOx), and a method of combustion. The fuel injector includes three fuel/oxider flow path channels. The first channel includes a flow balancing insert and provides a relatively straight flow. The second channel includes at least one angled vane that imparts a swirl to the flow. The third channel is a central tube, the first channel annularly surrounding the third channel, the second channel annularly surrounding the first channel.

Abstract: Present gas turbine engines fail to effectively and efficiently control the emission emitted therefrom. Many existing systems estimate the amount of constituents emitted within the exhaust gas verses measuring the actual quantity of constituent emitted within the exhaust gas. The present exhaust gas monitoring system has the ability to measure the actual quantity of an emission constituent, such as carbon monoxide (CO), sends a signal to a control box, interprets the signal, sends a second signal to an actuation device controlling a fluid flow to the combustion section resulting in the controlling of emissions emitted from the gas turbine engine within the exhaust gas.

Abstract: A fuel injection nozzle includes a first cavity having a first preestablished cross-sectional area and a second preestablished cross-sectional area being larger than the first preestablished cross-sectional area. And, an actuating device being positioned at an inlet end of the first cavity and controllably varying the flow of a compressed fluid through the fuel injection nozzle. The fuel injection nozzle further including a second cavity having a flow of compressed fluid flowing therethrough.

Abstract: A premix fuel injection nozzle includes a first mixing chamber having a preestablished cross-sectional area and a second mixing chamber having a preestablished cross-sectional areal being larger than the preestablished cross-sectional area of the first mixing chamber. The first mixing chamber and the second mixing chamber are in communication with each other.

Abstract: The known control systems for reducing NOx in the combustion systems of past gas turbine engines has incorporated a variety of expensive and complicated techniques to reduce the NOx level. The present apparatus reduces the formation of NOx within the combustion zone by controlling the air portion of the air/fuel ratio. The present apparatus includes a device for controllably varying the quantity of compressed air directed into a manifold resulting in controlling the air to a plurality of injection nozzles and into a combustor. A throttling mechanism moves between an open position and a closed position varying the flow rate of compressor air to the combustor apparatus provides an economical, reliable and effective method for reducing and controlling the amount of nitrogen oxide (NOx) carbon monoxide (CO) and unburned hydrocarbon (UHC) emitted from the gas turbine engine.

Abstract: The known systems and injector nozzles for reducing NOx in the combustion systems of past gas turbine engines has generally failed to effectively and efficiently reduce the NOx level. The present system reduces the formation of NOx within the combustion zone by controlling the air/fuel ratio and more explicitly by controlling the air portion of the air/fuel ratio. The present injector nozzle includes a device for introducing a primary supply of air through the injector nozzle which is sized to have a predetermined cross-sectional area. The injector nozzle further includes a device for introducing a secondary supply of air through the injector nozzle which is sized to have a predetermined area. A device for introducing a primary supply of air through the injector at a controlled rate and a device for passing a main source of fuel through the injector nozzle at a controlled rate relative to the quantity of primary supply of air.
