20090139235 | Catalytically Stabilized Gas Turbine Combustor - A gas turbine combustor. The gas turbine combustor may include a central combustion nozzle with a catalyst therein and a number of outer combustion nozzles surrounding the central combustion nozzle. | 06-04-2009 |
20100175379 | PRE-MIX CATALYTIC PARTIAL OXIDATION FUEL REFORMER FOR STAGED AND REHEAT GAS TURBINE SYSTEMS - A gas turbine system includes a fuel reformer comprising: a fuel inlet; an oxygen inlet; a pre-mixing zone configured to mix the fuel and the oxygen in a pre-mixing device to form a gaseous pre-mix; wherein the pre-mixing device comprises a flow conditioning device configured to pre-condition the fuel stream, wherein the flow conditioning device is disposed upstream of the oxygen inlet; a diffuser disposed downstream of the flow conditioning device; a catalytic partial oxidation zone disposed downstream of the diffuser, wherein the catalytic partial oxidation zone comprises a catalyst composition configured to react the fuel and the oxygen to generate a syngas. The generated syngas is then mixed with rest of the fuel to form a hydrogen-enriched fuel mixture, which is then sent to the combustion chamber of a gas turbine to reduce the NOx emission and extend the lean blow out limit. | 07-15-2010 |
20100180597 | SYSTEM AND METHOD EMPLOYING CATALYTIC REACTOR COATINGS - Methods and apparatuses are provided for protecting a catalyst within a combustor. In one embodiment, a catalytic reactor includes a protective coating that may be chemically removed or mechanically removed while the catalytic reactor is disposed in a combustor. | 07-22-2010 |
20110067401 | LEAN FUEL INTAKE GAS TURBINE SYSTEM - Provided is a lean fuel sucking gas turbine system including a compressor for compressing a mixed gas having a fuel and air mixed to a concentration of an inflammable limit or lower, thereby producing a compressed gas, a first catalyst combustor for burning the compressed gas by a catalyst reaction, a turbine adapted to be driven by a combustion gas from a second catalyst combustor, and a reproducer for heating the compressed gas to be introduced into the first catalyst combustor with an exhaust gas from the turbine. Between the turbine and the reproducer, there is arranged a duct burner for flame-burning a first auxiliary fuel in the exhaust gas. Thus, it is possible to attain efficient operation of the system while simplifying the entire constitution and to prevent the blow-by of the mixed gas. | 03-24-2011 |
20110113783 | PREMIXING APPARATUS FOR FUEL INJECTION IN A TURBINE ENGINE - In one embodiment, a system includes a fuel nozzle that includes a fuel injector that includes a fuel port and a premixer tube. The premixer tube includes a wall disposed about a central passage, multiple air ports extending through the wall into the central passage, and a catalytic region. The catalytic region includes a catalyst, disposed inside the wall along the central passage, configured to increase a reaction of fuel and air. | 05-19-2011 |
20130125548 | FLOW CONDITIONER FOR FUEL INJECTOR FOR COMBUSTOR AND METHOD FOR LOW-NOx COMBUSTOR - 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. | 05-23-2013 |
