摘要： The invention is a method and apparatus for use therewith for a main burner of a gas turbine. The method employs catalytic combustion to support main combustion. More specifically, a rich fuel/air mixture is catalytically oxidized with the resulting reacted mixture being made lean by having additional air added thereto. The resulting lean mixture is then combusted in the presence of the main mixture that is also lean thereby supporting combustion of the main mixture. The method allows for enhanced turndown of a lean main mixture.

摘要： The present invention provides a combustor for an aerospace gas turbine engine comprising two stages wherein each stage defines an inlet and an exit. The second stage inlet is in fluid communication with the first stage exit such that a first flowpath is defined and it passes substantially through the second stage. A plurality of flow channel tubes is positioned within the second stage and each flow channel tube passes sealingly through a header plate positioned upstream of the second stage inlet thereby defining a second flowpath that also passes substantially through the second stage. The first flowpath exit and the second flowpath exit are positioned adjacent and proximate to one another to provide for the generation of microflames or microflame jets exiting the second stage from between and around the flow channel tube exits. The first stage of the combustor provides a gasifier and a reformer. The present invention also may comprise an igniter for further combustion of the reacted products or an external heat source for start-up. The second stage also may comprise a microflame combustor.

摘要： A catalytic firebox reactor employing an exothermic catalytic reaction channel and multiple cooling conduits for creating a partially reacted fuel/oxidant mixture. An oxidation catalyst is deposited on the walls forming the boundary between the multiple cooling conduits and the exothermic catalytic reaction channel, on the side of the walls facing the exothermic catalytic reaction channel. This configuration allows the oxidation catalyst to be backside cooled by any fluid passing through the cooling conduits. The heat of reaction is added to both the fluid in the exothermic catalytic reaction channel and the fluid passing through the cooling conduits. After discharge of the fluids from the exothermic catalytic reaction channel, the fluids mix to create a single combined flow. A further innovation in the reactor incorporates geometric changes in the exothermic catalytic reaction channel to provide streamwise variation of the velocity of the fluids in the reactor.

摘要： The present invention provides a method for the reduction of pressure drop in low NOx combustion of fuel and air, maximizing energy efficiency. A supply of fuel and a supply of air form a fuel rich mixture that is reacted to produce partial reaction products and heat. A portion of the heat is transferred to a second supply of air. The partial reaction products are mixed with heated air and with a third supply of air to form a fuel lean admixture that is passed to a combustion zone for low NOx combustion.
