Abstract
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 2 from fuels. A lamina flow is produced which is folded over and reversed in direction within the combustion chamber.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
215 words
In an internal combustion apparatus, the combination which comprises: a burner means having at least one internal combustion chamber for combusting air and hydrocarbon fuels at fuel-rich stoichiometric air/fuel ratios within the range from 0.25 to 1.0 to provide air/fuel vapors; injector means disposed in said burner means for separately introducing air and fuel into said combustion chamber; said injector means includes an air inlet tube and a fuel inlet tube having open ends terminating in close proximity with respect to each other; a cup-like thimble disposed about a spaced relationship to said open ends of said air inlet: tube and said fuel inlet tube for simultaneously receiving introduced air and fuel; said thimble including a flat barrier wall and a continuous sidewall terminating in an edge about said open ends for receiving said introduced air and fuel in forced impingement relationship to create an air/fuel mixture in said combustion chamber; said barrier wall is disposed immediately ahead of said introduced air and fuel for receiving and redirecting said air/fuel mixture to further blend said air/fuel mixture; a heat exchanger disposed in said combustion chamber about said injector means; and a source of pressurized moisture connected to said heat exchanger to provide liquid water or steam to said air inlet tube of said injector means.

Claim 3
Dependent Claim
184 words
An underoxidized burner comprising: a burner means having at least one internal combustion chamber for combusting a mixture of air and hydrocarbons fuel to provide air/fuel vapors; injector means disposed in said burner means for separately introducing air and fuel into said combustion chamber; said injector means includes an air feed tube and a fuel feed tube, each having an open end terminating in close proximity in co-axial space apart relationship with respect to each other; a supply of moisture connected to said air feed tube for addition with said air/fuel vapor mixture to produce maximum hydrogen H 2 from fuels; an impact barrier disposed about and in spaced apart relationship to said open ends of said air feed tube and said fuel feed tube for simultaneously receiving introduced air and fuel; said impact barrier having a flat wall for receiving said introduced air and fuel in forced impingement relationship to create an air/fuel vapor mixture; and said barrier flat wall disposed immediately ahead of said introduced air and fuel for receiving and redirecting said air/fuel vapor mixture to further blend said air/fuel mixture.
Claim 4
Dependent Claim
184 words
An underoxidized burner comprising: a burner means having at least one internal combustion chamber for combusting a mixture of air and hydrocarbons fuel to provide air/fuel vapors; injector means disposed in said burner means for separately introducing air and fuel into said combustion chamber; said injector means includes an air feed tube and a fuel feed tube, each having an open end terminating in close proximity in co-axial space apart relationship with respect to each other; a supply of moisture connected to said air feed tube for addition with said air/fuel vapor mixture to produce maximum hydrogen H 2 from fuels; an impact barrier disposed about and in spaced apart relationship to said open ends of said air feed tube and said fuel feed tube for simultaneously receiving introduced air and fuel; said impact barrier having a flat wall for receiving said introduced air and fuel in forced impingement relationship to create an air/fuel vapor mixture; and said barrier flat wall disposed immediately ahead of said introduced air and fuel for receiving and redirecting said air/fuel vapor mixture to further blend said air/fuel mixture.
Claim 5
Dependent Claim
37 words
The invention as defined in claim 2 wherein: said air/fuel vapor mixture exits said injector means as a lamina flow which is folded over and impinges against aid combustion chamber to reverse in direction prior to exhaust.
Claim 6
Dependent Claim
89 words
The invention as defined in claim 3 including: said combustion chamber having an exhaust for carrying combusted gases exteriorly of said burner means; a source of water under pressure; a water feed tube connected to said source of water and having an open end terminating with said combustion chamber in close proximity to said injector means; and a water dispersal device disposed at said water feed tube opening for distributing water into combusted air/fuel vapor mixture constituting an effluent preparatory for exhaust from said burner means via said exhaust.
