Patent number: 8105074Abstract: 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.Type: GrantFiled: June 24, 2009Date of Patent: January 31, 2012Assignee: Praxair Technology, Inc.Inventors: William John Mahoney, Bryan R.

Patent number: 8096803Abstract: Apparatus for enhancing combustion of an undesired chemical to minimize the formation of smoke during operation of a flare stack for the discharge of a flare feedstream includes a plurality of high-pressure air nozzles spaced apart below and around the periphery of the stack outlet. Each nozzle is directed toward the stack outlet and in the direction of the feedstream's movement. High-pressure air from the nozzles forms a plurality of high-velocity air jets to produce a moving air mass that draws additional atmospheric air into the air mass moving toward the stack outlet to enhance combustion of the flare feedstream. Analytical means determine the stoichiometric oxygen requirements, and an air-flow valve controls the flow rate of the high-pressure air to the nozzles.Type: GrantFiled: February 7, 2008Date of Patent: January 17, 2012Assignee: Saudi Arabian Oil CompanyInventors: Mazen Mashhour, M.

Patent number: 8065998Abstract: A cooking apparatus includes a housing and a cooking plate. Burners are located within the housing and below the cooking plate. A non-powered mechanical thermocouple probe is proximate to a pilot burner with a bi-metal element that produces an electrical signal when heated by the pilot burner. A pilot shutoff valve has an inlet connected to receive gaseous fuel from a gaseous fuel manifold, a pilot output connected to deliver gas to the pilot burner, a main burner output connected to deliver gas the burners, and a thermocouple probe input connected to receive the electrical signal produced by the bi-metal element. The pilot shutoff valve is biased to a default closed position where gas is prevented from flowing from the inlet to the pilot output and from the inlet to the main burner output. When the pilot shutoff valve is open, the pilot shut off valve permits gas to flow from the inlet to the pilot output and from the inlet to the main burner output.Type: GrantFiled: March 23, 2009Date of Patent: November 29, 2011Assignee: ITW Food Equipment Group LLCInventors: Miguel A.
