A burner apparatus for reducing carbon production, comprises a burner having a combustion chamber and a heat exchanger located within the combustion chamber. The heat exchanger has an inlet end where a mixture comprising air and fuel enters, a heat transfer section, and an outlet end from which a process mixture of air and fuel discharges into the combustion chamber and is ignited to produce a product mixture. The inlet end and outlet end are located such that the general flow direction of the air and fuel within at least a portion of the heat transfer section is substantially parallel with flow direction of the product mixture in the combustion chamber. The heat transfer section is located within the combustion chamber so as to receive thermal input from the combusted product mixture therein to heat the process mixture to a temperature sufficiently high to substantially reduce the production of solid carbon therein. The invention is also for a method for reducing carbon production.

Reduced carbon from under oxidized burner

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 additional to heat.

Integrated power module

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.

Dynamic fluid injector

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.

Shift reactor for use with an underoxidized burner

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.

Underoxidized burner utilizing improved injectors

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.

Emissions reduction system for internal combustion engines

A high performance methanol fuel is described. In the present invention, the methanol fuel is formulated with approximately 3-15% high purity water, resulting in an aqueous fuel whose properties are independent of subsequent condensation of water from the environment. A low concentration dye, in the range of 0.0005 to 0.0020 weight percent, is utilized to impart color to the liquid fuel. In the preferred embodiment, arazine yellow, manufactured by Chem Serv is utilized, and has no noticable effect on fuel properties. A low concentration of alkali metal salts, such as sodium or lithium carbonate, or a low concentration of alkaline earth salts such as calcium or strontium acetate, in the range of 0.0005 to 0.001 weight percent is utilized as a flame colorant. Improved lubricity of the methanol fuel of the present invention is achieved by utilizing a flourosurfactant of about 0.05 percent by weight. In the preferred embodiment, ZONYL manufactured by DUPONT, is utilized. In order to test the effectiveness of the lubricating additive, a simple test in which an electric motor driven pump is used to maintain a constant flow rate of a fuel containing lubricating agent is performed. By measuring the wattage required to maintain the constant pumping rate for a variety of fuels containing different percentages and different compositions of lubricating agents, meaningful comparisons can be achieved.

Methanol fuel mixture

An integrated power system is located adjacent a body of saline water. The power system includes a solar powered and a wind driven engine. Desalinization and electrolysis of the water is provided. The system produces carbon dioxide and hydrogen which are used to generate methanol. The methanol can be used as a fuel to drive a combustion engine.

Self-contained renewable energy system

A chemical heat pump system is disclosed for use in heating and cooling structures such as residences or commercial buildings. The system is particularly adapted to utilizing solar energy, but also increases the efficiency of other forms of thermal energy when solar energy is not available. When solar energy is not available for relatively short periods of time, the heat storage capacity of the chemical heat pump is utilized to heat the structure, as during nighttime hours. The design also permits home heating from solar energy when the sun is shining. The entire system may be conveniently rooftop located. In order to facilitate intallation on existing structures, the absorber and vaporizer portions of the system may each be designed as flat, thin wall, thin pan vessels which materially increase the surface area available for heat transfer. In addition, this thin, flat configuration of the absorber and its thin walled (and therefore relatively flexible) construction permits substantial expansion and contraction of the absorber material during vaporization and absorption without generating voids which would interfere with heat transfer.
