Abstract
Abstract A hydrogen gas burner for the mixture of hydrogen gas with ambient air and non-combustible gasses. The mixture of gasses when ignited provides a flame of extremely high, but controlled intensity and temperature. The structure comprises a housing and a hydrogen gas inlet directed to a combustion chamber positioned within the housing. Ambient air intake ports are provided for adding ambient air to the combustion chamber for ignition of the hydrogen gas by an ignitor therein. At the other end of the housing there is positioned adjacent to the outlet of the burner (flame) a barrier/heating element. The heating element uniformly disperses the flame and in turn absorbs the heat. The opposite side to the flame, the heating element uniformly disperses the extremely hot air. A non-combustible gas trap adjacent to the heating element captures a small portion of the non-combustible gas (burned air). A return line from the trap returns the captured non-combustible gas in a controlled ratio to the burning chamber for mixture with the hydrogen gas and the ambient air.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
141 words
A hydrogen gas burner for utilization as a heat source comprising: a housing having a double open-end combustion chamber positioned therein, a source of hydrogen gas and a nozzle connected thereto for directing the hydrogen gas into one end of said combustion chamber, ambient air intake means in said housing positioned to direct ambient air into said combustion chamber, and a source of a non-combustible gas, return line means for returning said non-combustible gas to said combustion chamber for mixing with said hydrogen gas and said ambient air, an ignitor for igniting said mixture of gasses, a barrier positioned adjacent to other open-end of said combustion chamber, said ignited mixture of gasses superheating the air in said housing and directing the same to said barrier, said barrier further comprising a heat dissapating surface to disperse heated air to the utilization means.
Claim 2
Dependent Claim
141 words
A hydrogen gas burner for utilization as a heat source comprising: a housing having a double open-end combustion chamber positioned therein, a source of hydrogen gas and a nozzle connected thereto for directing the hydrogen gas into one end of said combustion chamber, ambient air intake means in said housing positioned to direct ambient air into said combustion chamber, and a source of a non-combustible gas, return line means for returning said non-combustible gas to said combustion chamber for mixing with said hydrogen gas and said ambient air, an ignitor for igniting said mixture of gasses, a barrier positioned adjacent to other open-end of said combustion chamber, said ignited mixture of gasses superheating the air in said housing and directing the same to said barrier, said barrier further comprising a heat dissapating surface to disperse heated air to the utilization means.
Claim 3
Dependent Claim
39 words
The hydrogen gas burner of claim 1 wherein said source of non-combustible gas further comprises a hot air trap adjacent to the heat dissapating surface of said barrier and a return line from said trap to said combustion chamber.
Claim 4
Dependent Claim
26 words
The hydrogen gas burner of claim 1 wherein said return line further comprises valve means for controlling the amount of non-combustible gas entering said combustion chamber.
Claim 5
Dependent Claim
31 words
The hydrogen gas burner of claim 1 wherein said ambient air intake means is positioned in said housing to provide ambient air to said combustion chamber together with said hydrogen gas.
Claim 6
Dependent Claim
32 words
The hydrogen gas burner of claim 1 wherein said ambient air intake means in said housing further comprises a valve means for controlling the amount of ambient air entering said combustion chamber.
Claim 7
Dependent Claim
30 words
