Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
A method of generating heat within a flueless space heater, which comprises: (a) creating a swirling fuel flow; (b) creating a counter-swirling primary air flow, with respect to the swirling fuel flow, primary air of the primary air flow containing approximately 60 to 75 percent of a stoichiometric amount of oxygen required for complete combustion of fuel of the swirling fuel flow; (c) mixing the swirling fuel flow and the counter-swirling primary air flow forming a fuel/air mixture; (d) igniting the fuel/air mixture; (e) burning the fuel/air mixture in a combustion chamber; and (f) postburning the fuel/air mixture in the combustion chamber.
Claim 2
Independent Claim
102 words
A method of generating heat within a flueless space heater, which comprises: (a) creating a swirling fuel flow; (b) creating a counter-swirling primary air flow, with respect to the swirling fuel flow, primary air of the primary air flow containing approximately 60 to 75 percent of a stoichiometric amount of oxygen required for complete combustion of fuel of the swirling fuel flow; (c) mixing the swirling fuel flow and the counter-swirling primary air flow forming a fuel/air mixture; (d) igniting the fuel/air mixture; (e) burning the fuel/air mixture in a combustion chamber; and (f) postburning the fuel/air mixture in the combustion chamber.
Claim 3
Dependent Claim
44 words
A method for generating heat within a flueless space heater according to claim 1 wherein the burned fuel/air mixture is further quenched by introducing secondary air flow by admitting secondary air through at least one secondary air supply hole of a combustion chamber wall.
Claim 4
Dependent Claim
61 words
A method for generating heat within a flueless space heater according to claim 2 wherein the combustion chamber has a circular cross section and each secondary air supply hole has a centerline disposed at an angle to the radius of the combustion chamber intersecting the centerline of the secondary air supply hole at the inside surface of the combustion chamber wall.
Claim 5
Dependent Claim
20 words
A method for generating heat within a flueless space heater according to claim 3 wherein said angles are approximately 30°.
Claim 6
Dependent Claim
110 words
In a method of generating heat within a flueless space heater, of the type wherein a fuel/air mixture is ignited, the fuel/air mixture is burned in a combustion chamber, and the fuel/air mixture is postburned in the combustion chamber, the improvement comprising; creating a swirling fuel flow, creating a counter-swirling primary air flow with respect to the swirling fuel flow, the primary air flow containing primary air at an amount of approximately 60 to 75 percent of a stoichiometric amount of oxygen required for complete combustion of a fuel of the swirling fuel flow and mixing the swirling fuel flow and the counter-swirling primary air flow forming the fuel/air mixture.
Claim 7
Dependent Claim
110 words
In a method of generating heat within a flueless space heater, of the type wherein a fuel/air mixture is ignited, the fuel/air mixture is burned in a combustion chamber, and the fuel/air mixture is postburned in the combustion chamber, the improvement comprising; creating a swirling fuel flow, creating a counter-swirling primary air flow with respect to the swirling fuel flow, the primary air flow containing primary air at an amount of approximately 60 to 75 percent of a stoichiometric amount of oxygen required for complete combustion of a fuel of the swirling fuel flow and mixing the swirling fuel flow and the counter-swirling primary air flow forming the fuel/air mixture.
