Abstract
Abstract The fuel chamber of the effluent burner is insulated from the surrounding effluent to maintain the temperature of the fuel below its ''''cracking point.'''' The effluent is heated beyond the cracking point of the natural gas or other fuels prior to burning.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
89 words
An apparatus for burning effluent comprising: a body forming a chamber for gaseous fuel; a second body forming a chamber for effluent to be burned with said gaseous fuel mounted about said first body; a third body forming a third chamber disposed about said first body within said second body; and insulating means within said third chamber coacting therewith to provide insulation about said first chamber to maintain the temperature of the gaseous fuel in the first chamber lower than tHe temperature of the effluent in the second chamber.
Claim 2
Independent Claim
89 words
An apparatus for burning effluent comprising: a body forming a chamber for gaseous fuel; a second body forming a chamber for effluent to be burned with said gaseous fuel mounted about said first body; a third body forming a third chamber disposed about said first body within said second body; and insulating means within said third chamber coacting therewith to provide insulation about said first chamber to maintain the temperature of the gaseous fuel in the first chamber lower than tHe temperature of the effluent in the second chamber.
Claim 3
Independent Claim
59 words
A method of burning effluent comprising: the steps of providing a gaseous fuel from a source to a burner; heating the effluent to a temperature above the cracking temperature of the gaseous fuel; and exposing the gaseous fuel to the heat of the effluent while maintaining the gaseous fuel at a temperature below its cracking temperature prior to combustion.
Claim 4
Independent Claim
59 words
A method of burning effluent comprising: the steps of providing a gaseous fuel from a source to a burner; heating the effluent to a temperature above the cracking temperature of the gaseous fuel; and exposing the gaseous fuel to the heat of the effluent while maintaining the gaseous fuel at a temperature below its cracking temperature prior to combustion.
Claim 5
Independent Claim
82 words
A method, for increased thermal efficiency, of burning effluent above the cracking temperature of a gaseous fuel without resulting in pollutant products of pre-combustion, comprising the steps of: providing heated effluent at a temperature above the cracking temperature of the gaseous fuel, maintaining a source of the gaseous fuel below the cracking temperature of the gaseous fuel by insulating it from the heated effluent, and then supplying the gaseous fuel from the insulated source to a burner exposed to the heated effluent.
Claim 6
Independent Claim
82 words
A method, for increased thermal efficiency, of burning effluent above the cracking temperature of a gaseous fuel without resulting in pollutant products of pre-combustion, comprising the steps of: providing heated effluent at a temperature above the cracking temperature of the gaseous fuel, maintaining a source of the gaseous fuel below the cracking temperature of the gaseous fuel by insulating it from the heated effluent, and then supplying the gaseous fuel from the insulated source to a burner exposed to the heated effluent.
Claim 7
Independent Claim
123 words
An apparatus, of increased thermal efficiency, for burning effluent above the cracking temperature of a gaseous fuel without resulting in pollutant products of pre-combustion, comprising: a first body forming a first chamber for the gaseous fuel; a second body forming a second chamber for effluent heated above the cracking temperature of the gaseous fuel, mounted about said first body; a third body forming a third chamber disposed about said first body within said second body; and insulating means within said third chamber co-acting therewith to provide insulation about said first chamber from the heat of the effluent so as to maintain the temperature of the gaseous fuel within said first chamber at a temperature lower than the cracking temperature of the gaseous fuel.
Claim 8
