Patent number: 6200430Abstract: A method, and its associated equipment, for producing synthetic gas by means of an electric arc-activated, non-catalytic burner which utilizes up to three streams of product inputs. A primary spray is heated by an electric arc formed between two electrodes. A second spray is then injected and mixed with the heated primary fluid. The resulting high-temperature, high pressure mixture is combined with a tertiary spray, an oxidant. The end product thereby produced is a synthetic gas, which becomes immediately available for combustion in furnaces, reactors, and other processes in the chemical, petroleum, and metals fabrication industries. The invention overcomes the deficiencies of existing processes.Type: GrantFiled: September 14, 1998Date of Patent: March 13, 2001Inventor: Edgar J. Robert

Patent number: 4255646Abstract: A compact, economical electrically heated vaporizer having a fast response time and capable of vaporizing liquified petroleum gas at a rate of ten to forty gallons or more per hour with safety and without excessive superheating and/or cracking of the liquified petroleum gas utilizes a metal casting having a closed internal cavity separated into two chambers by an integral barrier. The casting serves as a pressure vessel and heat sink as well as providing a heated interface between electric resistance heaters received in passageways in the barrier and the liquified petroleum gas. The heat generated by the heaters is disseminated uniformly throughout the casting surrounding the chambers. The liquified petroleum gas inlet at one end of the casing connects with the end of one chamber. Multiple small passageways in the barrier at the other end of the casting connect the other end of the one chamber to the adjacent end of the other chamber.Type: GrantFiled: March 3, 1978Date of Patent: March 10, 1981Assignee: Sam Dick Industries, Inc.Inventors: Jens T.

Patent number: 4145998Abstract: A hot fuel gas generator for an internal combustion engine simultaneously vaporizes gasoline and water in a multi-chambered heated pressure vessel having built in regulators for controlling pressure and volume and delivers the resulting superheated steam and gaseous fuel to the internal combustion engine downstream from the usual carburetor. A single device operating at a very high temperature, for example 1600.degree. F., is used for the simultaneous vaporization of the fuel and water to develop desirable working pressure and volume. The high temperature steam and gaseous fuel positions the fuel molecules at the greatest degree of separation from each other providing the greatest opportunity for contact of the oxygen, the reacting species in the gaseous condition as chemical reactions occur only between particles at the atomic or molecular level and it is necessary for the reacting species to be in actual contact at the time of reaction.Type: GrantFiled: January 24, 1977Date of Patent: March 27, 1979Assignee: Econo Fuel Systems, Inc.Inventors: Fred G.

Patent number: 4112889Abstract: A fuel system for an internal combustion engine of the piston type vaporizes a liquid fuel and water and mixes the resulting gaseous fuel and water vapor with air in a metering valve which communicates with the internal combustion engine. A device operating at a very high temperature, for example 1800.degree. F. is used in the vaporization of the fuel. The high temperature gaseous state of the fuel represents molecules of the greatest degree of separation from each other providing the greatest opportunity for contact of the reacting species in the gaseous condition as chemical reactions occur only between particles at the atomic or molecular level and it is necessary for the reacting species to be in actual contact at the time of reaction. The fuel system therefore enables complete combustion and the elimination of the atmospheric pollutants common in the operation of internal combustion engines.Type: GrantFiled: November 26, 1976Date of Patent: September 12, 1978Assignee: Energy Research Inc.Inventor: Webster B.

Patent number: 4112876Abstract: A generator with a reaction chamber containing a catalytic charge for reacting liquid hydrocarbons with an oxygen containing gas to form a fuel gas is ignited by first electrically heating a part of the catalytic charge, preferably a part in front of the exit of the reaction chamber, to above the start up temperature of the catalyst. Then, the heating is terminated and an internal combustion engine which draws a hydrocarbon/air mixture with an air number higher than for normal operation over the hot volume of catalyst is started. The exothermic reaction which sets in there heats up the catalytic charge. Finally, the air number is throttled down and the transition to continuous operation is made.Type: GrantFiled: September 9, 1976Date of Patent: September 12, 1978Assignee: Siemens AktiengesellschaftInventor: Hellmuth Mentschel

Patent number: 4106891Abstract: An electrical heating device employs a metallic felt body through which fluid to be heated is passed. The felt may be of polycrystalline metal whiskers, or non-metal whiskers or filaments with metal coating applied. The body is heated by contact with an element that is heated electrically. The fluid flows through the body in a relatively long path compared with the distance through which heat has to be conducted through the body from the element. The body is conveniently a hollow cylinder, the fluid flow being parallel to the axis and the heat being applied from the inner and outer tubes between which the felt body is disposed.Type: GrantFiled: September 16, 1976Date of Patent: August 15, 1978Inventor: Hermann J.

Patent number: 4092963Abstract: A vaporizer-regulator device is which liquid fuel intended for use in an internal combustion engine is vaporized by an electrically energized heating element. The liquid fuel is contained in a reservoir in which a constant fuel level is maintained during operation by inlet and outlet floats. The outlet float senses a rise in fluid level, operating a contact switch, cutting the electrical current to the heating element, and opening a reservoir outlet drain. The inlet float senses a lowering of fuel level and causes fresh fuel to be injected into the reservoir. In this manner, heating element temperature and reservoir fluid level is controlled during engine operation. The liquid fuel is fed by hydrostatic pressure into a vaporizing chamber and brought into contact with the heating element. The dry fuel vapor thus produced is drawn through a two stage control valve into an expansion chamber.Type: GrantFiled: February 24, 1977Date of Patent: June 6, 1978Inventor: Richard A. Vrooman

Patent number: 4033133Abstract: A hydrogen generator provides hydrogen rich product gases which are mixed with the fuel being supplied to an internal combustion engine for the purpose of enabling a very lean mixture of that fuel to be used, whereby nitrous oxides emitted by the engine are minimized. The hydrogen generator contains a catalyst which must be heated to a pre-determined temperature before it can react properly. To simplify the process of heating up the catalyst at start-up time, either some of the energy produced by the engine such as engine exhaust gas, or electrical energy produced by the engine, or the engine exhaust gas may be used to heat up air which is then used to heat the catalyst.Type: GrantFiled: March 22, 1976Date of Patent: July 5, 1977Assignee: California Institute of TechnologyInventors: John Houseman, Donald J.
