  • Patent number: 8540508
    Abstract: The invention relates to a method for burning a fluid fuel, in which fuel is reacted in a catalytic reaction, whereupon catalytically pre-reacted fuel continues to be burned in a secondary reaction. A swirling component is impressed onto the pre-reacted fuel, allowing the secondary reaction to be ignited in a spatially controlled manner, resulting in complete burnout. The invention further relates to a burner for burning a fluid fuel, in which the fuel outlet of a catalytic burner is disposed upstream of the fuel outlet of a primary burner in the direction of flow of the fuel within a flow channel such that the fuel is catalytically reacted. The catalytic burner is provided with a number of catalytically effective elements which are arranged such that a vortex is created in the flow channel. The invention can be applied particularly to combustion chambers of gas turbines.

  • Publication number: 20120160142
    Abstract: A method of selective catalytic NOX reduction in a power boiler and a power boiler with selective catalytic NOX reduction. Fuel is combusted in a furnace of the boiler and a flue gas stream that includes NOX is generated. The flue gas stream is conducted from the furnace along a flue gas channel to a stack. The flue gas stream is cooled in a heat recovery area, including an economizer section, arranged in the flue gas channel. At least a portion of the NOX is reduced to N2 in an NOX catalyst arranged in the flue gas channel downstream of the economizer section. The flue gas is further cooled, and heated air is generated in a gas-to-air heater arranged in the flue gas channel downstream of the economizer section and upstream of the NOX catalyst. The gas-to-air heater may be a tubular air heater or a heat exchanger with a recirculating heat transfer fluid.

  • Publication number: 20120164588
    Abstract: An exemplary embodiment provides a regenerative burner apparatus. The apparatus includes a burner housing having a gas channel and a single-stage heat regenerator equipped with a housing enclosing a fluid-porous heat regenerative media bed. A first gas passageway in the housing directly interconnects the gas channel and the lower surface of the media bed. A second gas passageway in the housing interconnects an opening in the housing communicating with the exterior and the upper surface of the media bed. This arrangement allows hot waste combustion gases to pass upwardly through the media bed so that any condensable contaminant in the gases condenses to a liquid and flows out of the bed under gravity before becoming solid and clogging the bed. The liquid contaminant may then be removed from the regenerator from a position below the media bed.

  • Patent number: 8196388
    Abstract: The present invention relates to a heating device for exhaust gas in an internal-combustion engine, which is driven by using LPG, LNG, a volatile oil, a light oil, biodiesel or oxygenated hydrocarbon being DME, the device consisting of a catalyst reactor reformer, an exhaust gas suction section and the second fuel supply device. The exhaust gas suction section is mounted for using oxygen included in the exhaust gas. When the heating device is driven, air and fuels are supplied to the catalyst reactor and the second fuel supply device via a single tube when the heating device is heated. The present invention provides with a heating device for exhaust gas capable of securing the durability of a heating device for exhaust gas and minimizing the amount of air supplied from the outside to the combustion reforming device by excluding carbon depositions in a tube due to a prolysis of LPG, LNG, a volatile oil, a light oil, biodiesel or oxygenated hydrocarbon being DME, and a method for driving the device.

  • Publication number: 20120129112
    Abstract: A method of and a system for combusting fuel in an oxyfuel combustion boiler. Fuel is fed to a furnace of the boiler. Oxidant gas that includes a mixture of substantially pure oxygen and recycled flue gas is fed to the furnace, prior to the feeding of the oxidant gas. At least a portion of the oxidant gas is preheated to generate preheated oxidant gas. The fuel is combusted with the oxidant gas in the furnace so as to generate steam and to produce the flue gas, and at least a portion of the steam is superheated to generate superheated steam. The preheating of the at least a portion of the oxidant gas is performed by using a heat exchanger that transfers heat from a portion of the superheated steam to the oxidant gas.

  • Patent number: 8105074
    Abstract: A stream of hot oxygen is formed by providing a duct and a fuel lance movable axially within the duct, flowing gaseous fuel out of the lance into the duct, mixing it in the duct with gaseous oxidant, flowing the mixture out of the duct into an atmosphere which is hot enough that it ignites the mixture without aid of an ignition source other than said atmosphere, and combusting said mixture in a flame that does not extend into said duct; then moving the lance so its fuel outlet approaches the duct exit orifice so that the base of said flame moves inside said duct to the fuel outlet; and then moving the lance to draw the fuel outlet and the flame attached thereto away from the exit orifice into the duct; and increasing the flow rate of gaseous oxidant in said duct, so that combustion of fuel within the duct heats uncombusted oxygen which emerges as a stream of hot oxidant.
