Patent number: 8826903Abstract: In the heat utilization installation (1) according to the invention several heat sources (2) are included which are provided each with a jet pump (16), (17), (18), (19). The heat sources (2) are connected to a heat carrier circuit system (7) which includes a single, central circulating pump or circulating pump unit (20). The individual jet pumps (16) to (19) are so controlled for the respective heat sources (2), the required operating temperatures with respect to temperature difference between the outlet and inlet and the flow volume are maintained or achieved. With the possibility of independent control of the flow volumes at the various heat sources (2), uniform fluid temperatures as required for a buffer store (22) or heat consumers can be maintained.Type: GrantFiled: February 16, 2011Date of Patent: September 9, 2014Assignee: Helmut Bälz GmbHInventor: Hans Günther Thoma

Patent number: 8763600Abstract: The present invention refers to a gas burner (16), in particular a gas burner for a cooktop, comprising a plurality of burning portions (40, 42, 44). A gas burner according to the present invention comprises a plurality of burning portions (40, 42, 44) adapted to receive a gas flow from gas supply means (20, 30, 36) that comprise injector means (20) adapted to eject a gas flow diverging along the flow direction (10) to define a spreading angle Y. The gas burner is characterized in that gas-flow adjusting means (24, 25) are provided for modifying said spreading angle Y such that said gas flow is enabled to supply one or more of said plurality of burning portions (40,42, 44) depending on the adjustment of said spreading angle Y.Type: GrantFiled: July 22, 2008Date of Patent: July 1, 2014Assignee: Electrolux Home Products Corporation N.V.Inventors: Cedric Catalogne, Lorenzo Gattei, Marco Starnini

Patent number: 8714969Abstract: The invention relates to a fuel combustion method in which one jet of fuel and at least two jets of oxidant are injected. According to the invention, the first jet of oxidant, known as the primary oxidant jet, is injected such as to be in contact with the jet of fuel and to produce a first incomplete combustion, the gases produced by said first combustion comprising at least one part of the fuel, and the second jet of oxidant is injected at a distance from the jet of fuel such as to combust with the part of the fuel present in the gases produced by the first combustion. Moreover, the primary oxidant jet is divided into two primary jets, namely: a first primary oxidant jet, known as the central jet, which is injected at the centre of the jet of fuel; and a second primary oxidant jet, knows as the sheathing jet, which is injected coaxially around the fuel jet.Type: GrantFiled: December 6, 2004Date of Patent: May 6, 2014Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Bertrand Leroux, Remi Pierre Tsiava

Patent number: 8702420Abstract: In one embodiment of a method for vaporizing liquids such as fuels, the liquid is sprayed into a chamber such that the spray does not impinge on any surface. The energy for vaporization is supplied through the injection of a hot diluent such as nitrogen or oxygen depleted air. Additional heat is added through the surface. In another embodiment, the liquid is sprayed onto a hot surface using a geometry such that the entire spray is intercepted by the surface. Heat is added through the surface to maintain an internal surface temperature above the boiling point of the least volatile component of the liquid. The liquid droplets impinging on the surface are thus flash vaporized. A carrier gas may also be flowed through the vaporizer to control the dew point of the resultant vapor phase mixture.Type: GrantFiled: December 8, 2005Date of Patent: April 22, 2014Assignee: LPP Combustion, LLCInventors: Michael J. Ramotowski, Richard Joklik, Casey Fuller, Ponnuthurai Gokulakrishnan, Leo Eskin, Glenn Gaines, Richard J. Roby, Michael S. Klassen

Patent number: 8529249Abstract: A flame holder system includes a modified torch body and a ceramic flame holder. Catch pin(s) are coupled to and extend radially out from the torch body. The ceramic flame holder has groove(s) formed in its inner wall that correspond in number and positioning to the catch pin(s). Each groove starts at one end of the flame holder and can be shaped to define at least two 90°turns. Each groove is sized to receive one catch pin therein when the flame holder is fitted over the end of the torch body. The flame holder is then manipulated until the catch pin(s) butt up against the end of the groove(s).Type: GrantFiled: September 25, 2007Date of Patent: September 10, 2013Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Henry H. Haskin, Peter Vasquez
