Abstract: A system for electrically controlling combustion includes a combustion chamber, one or more sensors, an actuator, and a controller. The controller detects dynamic instabilities based upon input regarding conditions in the combustion chamber from the sensors. The actuator electrically modulates combustion, and the controller operates the actuator to counteract the dynamic instabilities.

Abstract: An apparatus, system, and method are disclosed for power loss management in a nonvolatile data storage device. A monitor module initiates a power loss mode in the nonvolatile data storage device in response to a primary power source failing to supply electric power above a predefined threshold to the nonvolatile data storage device. A secondary power source supplies electric power to the nonvolatile data storage device for at least a power hold-up time during the power loss mode. A power loss module adjusts execution of in-process operations on the nonvolatile data storage device during the power loss mode so that essential in-process operations execute within the power hold-up time.

Abstract: A method is provided for achieving low NOx in the operation of a non-premixed combustion system by reacting a fuel-rich mixture to produce partial reaction products plus heat, transferring a portion of the heat to a bypass air stream, and passing the cooled partial reaction products into non-premixed contact and combustion with a stoichiometric portion of the heated bypass air stream. A supply of fuel and a supply of air is provided; and a fuel-rich mixture is formed and reacted to produce partial reaction products plus a heat of reaction. A portion of the heat of reaction is transferred to a bypass air stream and the cooled partial reaction products are passed into non-premixed contact and combustion with a stoichiometric portion of the heated bypass air stream.

Abstract: The present invention is a method, and an apparatus for practicing the method, that creates a product stream and a heat of reaction from a fuel-rich fuel/air mixture and then contacts the product stream with a sufficient quantity of additional air to completely combust all of the fuel, to which air a portion of the heat of reaction has been transferred.

Abstract: 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.

Abstract: The present invention is a method for operating a fuel-rich catalytic reactor in a catalytic combustion system, wherein two different fuels having dissimilar reactivity are consecutively used. In this method, a fuel-rich fuel/air mixture comprising a first fuel contacts a catalyst to create a product stream and a heat of reaction. The reactor is operated such that mass transfer of oxygen to the catalyst surface limits the rate of catalytic reaction. The catalyst is backside cooled by a cooling stream comprising air that extracts at least a portion of the heat of reaction before contacting the product stream. The cooling stream flow is sufficient to completely combust all of the remaining fuel. A second fuel is then substituted for the first fuel, and the steps are repeated.

Abstract: The invention is a stacked catalytic reactor structure employing backside cooling of the catalyst deposited therein wherein the exits from the catalytic passages are interstrafied and proximate to the exits from the backside cooling passages. The structure is designed to oxidize a fluid in the presence of a catalyst and transfer some heat of reaction into a second fluid and isolate the fluid to be reacted from the backside cooling fluid and then combine both fluids.

Abstract: The invention disclosed herein is a flow baffle for providing a generally uniform flow to a fluid within a catalytic reactor, which is characterized by a single flow channel. The invention, however, has general application to any single flow channel device. The flow baffle is inserted within the reactor in the single flow channel to cause the fluid flowing in the single flow channel to have a generally uniform flow field, instead of preferentially flowing down a periphery of the channel. The uniform flow field promotes the design optimization of the catalytic reactor.

Abstract: The invention disclosed herein is a method and apparatus for use therewith for creating flow passages of approximately equal cross section whereby a flow of a fluid through any passage will be approximately equal to the flow of a fluid through another passage.

Those pins are internally connected to ground or internally not connected thus facilitating sensing of logic signals prior to powering up the processor. The probed signals are used to control the power supplied to the processor by adjustment mechanisms applied to power regulator or programmable logic devices.
