MULTI-CHANNEL BURNER ASSEMBLY SIMULATANEOSULY ACCEPTING MULTIPLE DIFFERENT FUEL-AIR MIXTURES
A burner assembly comprising a burner casing having two or more separate chambers therein, the chambers being divided from each other by one or more walls. The assembly also comprises one or more input conduits each configured to deliver different fuel-air mixtures to at least one of the separated chambers.
1 . A burner assembly, comprising:
a burner casing having two or more separate chambers therein, the chambers being divided from each other by one or more walls; and
one or more input conduits each configured to deliver different fuel-air mixtures to at least one of the separated chambers.
2 . The assembly of claim 1 , wherein the burner casing includes a upper pan half and a lower pan half which are configured to fit together to define the separate chambers therein.
3 . The assembly of claim 1 , wherein the burner casing includes:
one or more sets of porting holes on one side of the burner casing, the different sets of porting holes configured to feed the fuel-air mixture from one of the chambers into a viewing portion of a heating apparatus; and
intake holes on the opposite side of the burner casing configured to receive the fuel-air mixtures from one of the input conduits.
4 . The assembly of claim 1 , wherein at least a first one of the separate chambers intertwines with at least a second one of the isolated chambers.
5 . The assembly of claim 1 , wherein a surface of the one or more input conduits rests on a surface of the burner casing, and an opening in the conduit surface is aligned with an intake hole in the burner casing such that the fuel-air mixture in the input conduit can flow into one or more of the chambers.
6 . The assembly of claim 1 , wherein the one or more input conduits includes separate input conduits, each input conduit having a separate air input window, and each of the separate input conduits are coupled to a separate input fuel line such that one of the input conduits delivers a first fuel-air mixture to a first one of the chambers and a second one of the conduits delivers a second fuel-air mixture to a second one of the chambers.
7 . The assembly of claim 1 , wherein at least one of the input conduits has a divider therein, the divider separating an input fuel flow into separate cavities, each of the cavities having a separate air flows thereto, one of the cavities delivering a first fuel-air mixture to a first one of the chambers and a second of the cavities delivering a second fuel-air mixture to a second one of the chambers.
8 . The assembly of claim 7 , wherein an input fuel line coupled to the at least one input conduit has two orifices the each separately deliver fuel to the separate cavities.
9 . The assembly of claim 1 , wherein a portion of at least one of the walls between two of the chambers separates flows of the different fuel-air mixtures from a first one of cavities and a second one of the cavities to the first chamber and the second chamber, respectively.
10 . The assembly of claim 1 , wherein the burner casing has three separate chambers, first and second ones of the chambers receiving two of the different fuel-air mixtures from a first one of the input conduits, and a third one of the chambers receiving one of the different fuel-air mixtures from a second one of the input conduits.
11 . The assembly of claim 1 , wherein the different fuel-air mixtures includes a first fuel-air mixture and a second fuel-air mixture provided from a same flow rate of fuel and two different flow rates of air, respectively.
12 . The assembly of claim 1 , wherein the different fuel-air mixtures includes a first fuel-air mixture and a second fuel-air mixture provided from a same flow rate of air and two different flow rates of fuel, respectively.
13 . The assembly of claim 1 , wherein the different fuel-air mixtures includes a first fuel-air mixture having an air-to-fuel volume ratio that is in a range of about 1:2 to about 1:3, and a second fuel-air mixture having an air-to-fuel volume ratio that is in a range of about 1:1 to 2:1.
14 . A fuel-fired heating apparatus, comprising:
a viewing insert located in an heating zone of the apparatus; and
a burner assembly located under the viewing insert, the burner assembly including:
a burner casing having two or more separate chambers therein, the chambers being divided from each other by one or more walls; and
one or more input conduits each configured to deliver different fuel-air mixtures to at least one of the separated chambers.
15 . The apparatus of claim 14 , wherein
a first set of porting holes in the top of the burner casing receiving an air-rich fuel-air mixture from one of the chambers are adjacent to the viewing insert are configured to produce a blue flame to thereby cause the viewing insert to glow when the air-rich fuel-air mixture is combusted, and,
a second set of porting holes in the top of the burner casing receiving a fuel-rich fuel-air mixture from another one of the chambers are configured to provide a yellow flame when the fuel-rich fuel-air mixture is combusted.
16 . The apparatus of claim 14 , wherein the apparatus is configured as a fireplace, a stove, or a fire-pit.
17 . The apparatus of claim 14 , wherein the viewing insert is configured as an artificial log-set or embers.
18 . A method of manufacturing a burner assembly, comprising:
providing a burner casing having two or more separate chambers therein, the chambers being divided from each other by one or more walls; and
coupling one or more input conduits, each configured to deliver different fuel-air mixtures, to at least one of the separated chambers.
19 . The method of claim 18 , wherein providing a burner casing includes coupling an upper pan half to a lower pan half to form the separate chambers therein.
20 . The method claim 18 , wherein coupling the one or more input conduits includes coupling at least one of the input conduits to two of the chambers.
