Appl. No.:

09/804601

Inventors:

Richard Woods - Irvine CA, US

David Moard - Pasadena CA, US

International Classification:

H01M008/06
B01D053/22
F02P001/00
C25B001/02

US Classification:

429/017000, 429/020000, 429/019000, 095/055000, 205/343000, 205/637000

Abstract:

An integrated power module for generating thermal and electrical power is provided within a housing which includes inlets for fuel and for air, a reformer chamber, a fuel cell stack, and a combustion chamber. Oxygen-containing gas, such as air, is introduced into the module along a path in one direction in heat exchange relationship with reaction products produced in the reaction chamber traveling in an adjacent path, preferably in an opposite direction, to preheat the incoming oxygen-containing gas. A nozzle having an injector for the fuel and for the oxygen-containing gas delivers these gases to the interior of the reformer chamber, where ignition is supplied by a suitable device. The reaction products from the reformer chamber are fed to a fuel cell which will consume certain of the reaction products, such as hydrogen gas, with oxygen provided from the reaction chamber acting as an oxidizing gas. Exchange between a cathode and an anode will effect the generation of current, as well as the production of water, which normally will be absorbed as steam and passed from the fuel cell. The current generated by the fuel cell can be delivered externally to a user, while hydrogen may be combusted downstream in the combustion chamber to provide an added thermal energy source for heating. In alternate embodiments of the power module, the fuel cell is used as a shift reactor and hydrogen purification device. The primary product of this module is purified hydrogen gas in addition to heat.

International Classification:

F23D 1144

US Classification:

431242

Abstract:

Apparatus is disclosed herein for reducing engine nitrogen oxide emissions by mixing hydrogen prepared from a portion or all of engine fuel within a simple burner. The apparatus includes an insulated burner having an internal combustion chamber for receiving either a portion of or all the gaseous fuel or liquid fuel for mixture with air and subsequent ignition by a spark plug. The chamber is within a feed preheater assembly. A mixing chamber is included having a series of baffles against which injected air and fuel vapor impinge causing thorough and complete air/fuel blending into a mixture subsequently ignited and burned, and then discharged into the combustion chamber of the engine itself. The pre-heating assembly raises the temperature of the incoming air/fuel mixture via a heat exchanging process with post combusted gases from the combustion chamber. The apparatus improves operability and performs by conserving energy by insulating the total burner, placing the burner section within the feed preheater assembly, and locating the feed mixture flow of the preheater adjacent to the outer insulation; and hydrogen output may be increased by reaction between carbon monoxide and water produced by the main reaction or added separately.

International Classification:

C10G 904

US Classification:

48107

Abstract:

Injectors are disclosed for use in an underoxidized burner having a single or double stage internal combustion chamber for receiving gaseous or liquid fuel such as diesel for mixture with air or oxygen and subsequent ignition by a spark plug. The injector includes feed conduits or tubes for simultaneously conducting air and fuel to a mixing device having a baffle arrangement against which separately injected air and fuel impinge causing a complete air/fuel blending which is ignited, burned and exhausted. The injector may accept effluent gases for mixing with water to produce maximum hydrogen H. sub. 2 from fuels. A lamina flow is produced which is folded over and reversed in direction within the combustion chamber.

US Classification:

431353

Abstract:

A fluid injector for use with a burner having at least a pair of concentric tubes which conduct at least two different fluids via inner and outer passageways to a discharge tip. The passageways having different linear fluid velocity rates which causes the issuing discharge flow of the fluids to constrict causing mixing and combining of the fluids for introducing to a combustion chamber. Protection of the injector from thermal melting or burning is provided by location of the injector within the coils of a feed preheater constituting a heat exchanger.

Abstract:

A shift reactor is disclosed that is mounted on the exhaust end of an underoxidized burner so that the exhaust product is introduced to a cooler water bath in a compartment of the reactor. The exhaust product is passed through the water bath via submerged gas diffusers. The reactor compartment includes a collection chamber for receiving the bathed exhaust product containing hydrogen gas which is then exited to a shift catalyst chamber. The latter includes eductor for recirculation. A conduit may be coupled to the water bath for distributing heated water from the bath for exterior heating purposes or for purification means. A drain is operably connected to the conduit for permitting removal of excess water and a fill inlet is provided for adding water.
