Patent number: 4668179Abstract: An oil burner of the wick ignition type is disclosed which is capable of effectively preventing the generation of bad odor due to unburned fuel oil gas after the fire-extinguishing operation as well as during the operation. The oil burner includes an air pumping mechanism. The mechanism comprises an air pumping means which is adapted to discharge air to a combustion cylinder construction when it is heated and suck air thereinto from the combustion cylinder construction when it is cooled and an air chamber arranged between the pumping means and the combustion cylinder construction so as to be communicated with the both. The air pumping means may comprise a rigid closed vessel formed of a heat transfer material and arranged to receive heat directly from the combustion cylinder construction.Type: GrantFiled: November 26, 1985Date of Patent: May 26, 1987Assignee: Toyotomi Kogyo Co., Ltd.Inventors: Kazuharu Nakamura, Yutaka Nakanishi

Patent number: 4650416Abstract: A combustor using D.sub.2 /NF.sub.3 /He is used in a laser gain generator in a cylindrical gas laser. The combustor includes a plurality of primary rings having fuel, oxidizer and diluent orifices therein. Fuel and oxidizer orifices form a triplet injector set that provides a reactant set. Two diluent orifices form a diluent injector set that provides a diluent set. These sets alternate about each primary ring and from one primary ring to the adjacent primary ring. Because the diluent set does not mix directly with the reactant set initially, a greater percentage of lasing products are formed because of the higher temperature in the reacting zone. Diluent is mixed as required at a later stage in the flow.Type: GrantFiled: November 8, 1985Date of Patent: March 17, 1987Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Walter R. Warren, Jr., Norman Cohen

Patent number: 4604050Abstract: The combustion gas passages leading to a fluidized bed in a hot water or steam boiler are kept free of deposits which might block them by pulses of gas. The gas pulses may be generated from a pressurized reservoir with periodic or aperiodic openings of a valve in a gas line leading from the reservoir to the passages. Where the bottom of a fluidized bed comprises a pair of plates defining a plenum space therebetween and the combustion gas passages define nozzles extending through the plenum space, combustion air may be fed to the nozzles via the plenum space and the cleaning pulses may also be generated from gas supplied to the plenum space.Type: GrantFiled: February 28, 1984Date of Patent: August 5, 1986Assignee: Stal-Laval Turbin ABInventor: Erik A.

Patent number: 4533316Abstract: There is disclosed a combustion apparatus of a fuel vaporizing type wherein fuel is led to a fuel injector for vaporization and the vaporized fuel is fed to a burner via a gas nozzle for combustion. The combustion apparatus features the provision of a device for removing at a high temperature tar attached in the fuel injector. Preferably, the removal of the tar is accomplished by fuel-empty burning. Therefore, there is no possibility that tar is deposited in the fuel injector, resulting in no faulty or incomplete combustion nor an accident to the combustion apparatus. It is further unnecessary to exchange the fuel injector or a vaporizing core installed therein or clear the interior of the fuel injector. The combustion apparatus demands only the fuel-empty burning device for the removal of tar with high temperature heating and is of simple and low cost structure. Controls are further provided for keeping constant the temperature of the fuel injector during fuel-empty burning.Type: GrantFiled: December 8, 1981Date of Patent: August 6, 1985Assignee: Sharp Kabushiki KaishaInventors: Kenichi Takino, Eiji Yamasaki, Kenji Murakami

Patent number: 4509914Abstract: A method for the combustion of liquid fuels in the gaseous state comprising the steps of evaporating fuel in a gasification chamber and burning the gasified fuel after it leaves the gasification chamber with a controlled amount of air. This is controlled by the pressure in the gasification chamber in such a way that the correct stoichiometric relationship between fuel and air is not altered by factors such as temperature and viscosity of the liquid fuel. The invention includes the apparatus used to carry out the process, and, particularly, means (37) to adjust air supply control means (25) according to the pressure in the gasification chamber (21).Type: GrantFiled: December 8, 1982Date of Patent: April 9, 1985Assignee: Stoechio-Matic AGInventor: Adolf Frick

Patent number: 4504214Abstract: A control valve for a resonant burner having a burner space for receiving active substance through a conduit with an atomizing nozzle discharging into the space is disclosed. When the valve is shut off to terminate flow of the active substance through the valve to the burner conduit, a spring action in the valve tends to withdraw the active substance from the conduit by creating a suction effect therein.Type: GrantFiled: December 29, 1981Date of Patent: March 12, 1985Assignee: Karl Heinz StahlInventors: Karl-Heinz Stahl, Fritz Fend

Patent number: 4465458Abstract: A liquid fuel combustion apparatus for evaporating and vaporizing kerosene, gas oil or like liquid fuel by heating, admixing air with the vaporized fuel in a specified ratio and burning the resulting gaseous mixture in a combustion unit. The vaporizer for the liquid fuel comprises a liquid fuel drawing-up member (15) made of a heat-resistant porous body (8) or heat-resistant inorganic fiber fabric (9) for drawing up the liquid fuel, and a heat generating member (6) including coating layers (22, 23) of heat-resistant metal, heat-resistant alloy or heat-resistant metallic oxide for giving heat to the drawing-up member. To prevent formation of tar-like substances, a catalyst is preferably deposited on the surface of the drawing-up member and/or on the surface of the heat generating member. Further preferably, the outer periphery of the heat generating member (6) is in contact with the drawing-up member (5).Type: GrantFiled: June 11, 1982Date of Patent: August 14, 1984Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Atsushi Nishino, Kazunori Sonetaka, Yasuhiro Takeuchi
