Abstract

A burner assembly for a gas furnace including a partition panel including an upstream side, a downstream side, at least two partition openings, and an intermediate transverse slot in communication with each of the at least two partition openings, wherein each partition opening is located adjacent to one another, and at least two burners configured to fire inward, the at least two burners operably coupled to the upstream side, wherein each burner is substantially aligned with each respective partition opening.

First claim

What is claimed is:

1 . A burner assembly comprising:
a partition assembly, the partition assembly comprising:
a partition panel including an upstream side, a downstream side, at least two partition openings, and an intermediate transverse slot in communication with each of the at least two partition openings, wherein each partition opening is located adjacent to one another; and
at least two burners configured to fire inward, the at least two burners operably coupled to the upstream side, wherein each burner is substantially aligned with each respective partition opening.

2 . The burner assembly of claim 1 , further comprising:
a combustion chamber including at least two chamber openings, an igniter and a flame sensor disposed therein, the combustion chamber operably coupled to the downstream side, wherein each chamber opening is substantially aligned with each respective partition opening; a mixture distribution box including an upstream wall and opposing side walls to form a cavity therein, wherein the mixture distribution box is operably coupled to the upstream side such that the at least two burners are disposed within the cavity; a mixing tube, including a mixing tube aperture, operably coupled to the mixture distribution box; and an orifice operable coupled to the mixing tube.

3 . The burner assembly of claim 2 , wherein the partition panel further comprises a first transverse slot in communication with the first of the at least two partition openings and a last transverse slot in communication with the last of the at least two partition openings.

4 . The burner assembly of claim 3 , further comprising a screen operably coupled to the downstream side, wherein the screen is configured to cover the first transverse slot, each intermediate transverse slot, and the last transverse slot.

5 . The burner assembly of claim 4 , wherein the igniter is disposed adjacent to the first transverse slot, and the flame sensor is located adjacent to the last transverse slot.

6 . The burner assembly of claim 4 , wherein the igniter is disposed adjacent to a first of the at least two burners, and the flame sensor is located adjacent to a last of the at least two burners slot.

7 . The burner assembly of claim 1 , wherein the at least two burners are composed from a woven material configured to be selectively permeated by an air-fuel mixture.

8 . A gas furnace comprising:
a heat exchanger including at least two heat exchanger inlets; a burner assembly operably coupled to the heat exchanger, the burner assembly comprising:
a partition assembly, the partition assembly comprising:
a partition panel including an upstream side, a downstream side, at least two partition openings, and an intermediate transverse slot in communication with each of the at least two partition openings, wherein each partition opening is located adjacent to one another other; and
at least two burners configured to fire inward, the at least two burners operably coupled to the upstream side;
wherein each burner is substantially aligned with each respective partition opening and each respective heat exchanger inlets.

9 . The gas furnace of claim 8 , further comprising:
a combustion chamber including at least two chamber openings, an igniter and a flame sensor disposed therein, the combustion chamber operably coupled to the downstream side, wherein each chamber opening is substantially aligned with each respective partition opening; a mixture distribution box including an upstream wall and opposing side walls to form a cavity therein, wherein the mixture distribution box is operably coupled to the upstream side such that the at least two burners are disposed within the cavity; a mixing tube operably coupled to the mixture distribution box; an orifice operable coupled to the mixing tube; and a valve operably coupled to the orifice.

10 . The gas furnace of claim 9 , wherein the partition panel further comprises a first transverse slot in communication with the first of the at least two partition openings and a last transverse slot in communication with the last of the at least two partition openings.

11 . The gas furnace of claim 10 , further comprising a woven material covering the first transverse slot, each intermediate transverse slot, and the last transverse slot.

12 . The gas furnace of claim 10 , wherein the igniter is disposed adjacent to the first transverse slot, and the flame sensor is located adjacent to the last transverse slot.

13 . The gas furnace of claim 8 , wherein the at least two burners are composed from a woven material configured to be selectively permeated by an air-fuel mixture.

14 . The gas furnace of claim 10 , wherein the igniter is disposed adjacent to a first burner of the at least two burners, and the flame sensor is located adjacent to a last of the at least two burners.
