Patent number: 9011142Abstract: A system for providing a combined water and fire display is provided. More specifically, a decorative display comprises a dynamic water and fire display device where fuel/air, water, and fire are integrated. The decorative display provides for unique aesthetic qualities and an appearance wherein flames are positioned at or near the surface of a volume of water. In various embodiments, the decorative display further comprises various safety features including the ability to detect and self-regulate conditions such as the existence and/or absence of a pilot flame, an adequate amount of water, and the temperature of various portions of the system. The decorative display further contemplates the ability to operate without one or more disclosed features, such as when only a water display or only a fire display is desired.Type: GrantFiled: June 19, 2013Date of Patent: April 21, 2015Inventors: William L. Muff, Timothy C. Muff

Patent number: 8740611Abstract: A fuel-fired high capacity liquid heating appliance, representatively a boiler or a water heater, has a fluid heat exchanger extending around a combustion chamber into which first and second fuel burners extend, the first and second burners respectively having associated blowers for supplying combustion air thereto. Illustratively, the combustion chamber is oval-shaped, with the burners extending into opposite ends the combustion chamber If one of the burners is not firing while the other burner is firing, a control system starts the non-firing burner's blower, to protect it from overheating by the firing burner, if the control system senses an excess temperature in the non-firing burner. The heat exchanger comprises a series of fluid receiving tubes extending between baffle-free header structures iteratively sized to equalize fluid flow rates through the heat exchanger tubes over a wide flow rate range.Type: GrantFiled: November 14, 2011Date of Patent: June 3, 2014Assignee: Rheem Manufacturing CompanyInventor: Raymond I.

Patent number: 8313324Abstract: A combustion apparatus is provided which includes an incoming fuel supply line that supplies fuel in a plurality of fuel-supply lines to one or more burners, the burners being associated with a combustion volume. A temperature sensor is located in the apparatus so as to yield temperature information relating to a component part of the apparatus, which is to be prevented from overheating The apparatus also includes a control arrangement, which detects the temperature-sensor output and, depending on that output, varies the fuel supplies to one or more of the burners in such a way as to maintain the temperature of the component part below a maximum value, while keeping the fuel in the incoming fuel supply line substantially constant. The control unit preferably also strives to adjust the operating conditions of the apparatus so that pressure oscillations are kept below a maximum value.Type: GrantFiled: December 8, 2006Date of Patent: November 20, 2012Assignee: Siemens AktiengesellschaftInventors: Ghenadie Bulat, Robin McMillan

Patent number: 8092948Abstract: The invention concerns an energy production unit, of electric energy in particular, comprising a fuel cell (1) and a heat source (2) thermally coupled to the fuel cell (1) at least to allow the rise in temperature of this fuel cell (1). According to the invention, it is provided that the heat source (2) comprises a radiating burner (20), that the fuel cell (1) is confined within a thermal insulation enclosure itself heated by the combustion gases (F) derived from the burner (20), and that this unit also comprises temperature regulation means (4) capable of controlling, from around 200° C. to at least 800° C., the temperature of the combustion gases (F) heating the enclosure 3.Type: GrantFiled: November 21, 2007Date of Patent: January 10, 2012Assignee: Gaz de FranceInventors: Stéphane Hody, Jean-François Fourmigue

Patent number: 5931660Abstract: A gas premix burner in which gas and air are mixed in a suction region of an impeller to form a combustion mixture. The impeller is associated with a blower housing and an electronic control circuit board, all of which are arranged upstream in a blower chamber having at least one flame separating wall. The arrangement prevents the gas and the combustion mixture from reaching the motor landings or the printed circuit board.Type: GrantFiled: October 17, 1997Date of Patent: August 3, 1999Assignee: Papst Motoren GmbH & Co. KGInventors: Wolfgang Amrhein, Fritz Schmider

Patent number: 4743194Abstract: A burner for operating in a high temperature and high pressure atmosphere such as in a fuel burning gasifier, requires a high degree of cooling such as by water circulation through the burner. In the event of physical breakage or damage to the normal cooling system, means is provided for introducing a higher pressure coolant into the system. The latter fills the system, both upstream and downstream of the cooling coil, to permit progressive discontinuance of the burner operation without substantial damage. It further avoids the backflow of gas from the high pressure gasifier which would otherwise be discharged to flow back through the cooling system and be discharged into the atmosphere thereby creating a dangerous as well as a harmful environment.Type: GrantFiled: March 13, 1987Date of Patent: May 10, 1988Assignee: Texaco Inc.Inventor: Robert J.

Patent number: 4431402Abstract: A waste gas flare igniter includes a pair of ignition tubes, each having a fuel line and an electrode extending therethrough to points near the ends of the tubes. The tubes are connected to an air distribution box which is slidably mounted on linear guides. A jackscrew and motor translate the air box and tubes between an extended position wherein the tubes connect with inwardly directed extensions passing through a heat shield at the end of the flare pipe for ignition of the waste gas and a retracted position spacing the tubes from the heat shield. The air box is connected by a telescoping duct to a blower, and the fuel line to a valve and pump to provide a fuel-air mixture which is ignited when the tubes are extended to ignite the waste gas.Type: GrantFiled: April 19, 1982Date of Patent: February 14, 1984Inventor: Louis F. Hamilton

Patent number: 4147495Abstract: Waste gas dispersion stacks are described, suitable for use on-shore and off-shore, for disposal of combustible gas without combustion by rapid dispersion into the atmosphere to reduce the waste gas concentration to below combustible or explosive levels, provisions being made to avoid ignition due to static electricity generation and to extinguish the flame by controlled utilization of an extinguishing medium if ignition should occur due to lightning or other causes. The stacks include single and multiple discharge pipes with diffuser or discharge heads for good mixing with air to provide a lean gas-air mixture.Type: GrantFiled: October 26, 1977Date of Patent: April 3, 1979Assignee: Combustion Unlimited IncorporatedInventor: John F.
