초록 ▼

A method for operating a fuel-fired furnace including at least one burner is provided. The method includes channeling a first fluid flow to the at least one burner at a first predetermined velocity, and channeling a second fluid flow to the at least one burner at a second predetermined velocity during a first mode of operation of the at least one burner. The second predetermined velocity is different than the first predetermined velocity.

대표청구항 ▼

What is claimed is: 1. A method for operating a fuel-fired furnace including at least one burner, said method comprising: mixing a far field and a near field substantially homogeneously by: channeling a first air flow to the at least one burner at a first predetermined velocity; channeling a second air flow to the at least one burner at a second predetermined velocity during a first mode of operation of the at least one burner, wherein the second predetermined velocity is different than the first predetermined velocity, and wherein during the first mode of operation, fuel is substantially prevented from being channeled through the at least one burner; and creating a recirculation zone by channeling a fuel flow through a flame regulation device to the at least one burner during a second mode of operation, wherein during the second mode of operation, the second air flow is substantially prevented from being channeled through the at least one burner. 2. A method in accordance with claim 1 wherein: channeling a second air flow to the at least one burner further comprises channeling the second air flow through a first duct; and channeling a fuel flow to the at least one burner further comprises channeling the fuel flow through a second duct that is substantially concentrically-aligned with and radially outward from the first duct. 3. A method in accordance with claim 1 wherein: channeling a first air flow to the at least one burner further comprises channeling the first air flow through a first passageway defined through the at least one burner; and channeling a second air flow to the at least one burner further comprises channeling the second air flow through a second passageway defined through the at least one burner. 4. A method in accordance with claim 3 wherein channeling the first air flow through a first passageway and channeling the second air flow through a second passageway further comprises channeling the first and second air flows through substantially concentrically-aligned first and second passageways. 5. A method in accordance with claim 1 wherein channeling a first air flow to the at least one burner further comprises channeling the first air flow to a burner at a downstream end of a combustion zone within the fuel-fired furnace. 6. A burner for use with a fuel-fired furnace, said burner comprising: a first duct configured to channel a fuel flow into the furnace, said first duct comprises a flame regulation device coupled to a downstream end of said first duct; a second duct substantially concentrically-aligned with and extending through said first duct, said second duct configured to channel a first air flow into the furnace, at a first predetermined velocity when the fuel flow is substantially prevented from flowing into the furnace through said first duct; and at least one third duct substantially concentrically-aligned with said first duct, said at least one third duct radially outward from said first duct and configured to channel a second air flow into the furnace at a second predetermined velocity that is different than the first predetermined velocity, wherein the first and second air flows facilitate substantially homogeneous mixing of a far field and a near field. 7. A burner in accordance with claim 6 wherein the fuel flow is a flow of air including fuel particulates entrained therein. 8. A burner in accordance with claim 6 wherein the second predetermined velocity is slower than the first predetermined velocity. 9. A burner in accordance with claim 6 further comprising an annular wall extending circumferentially between said first duct and said third duct. 10. A burner in accordance with claim 6 further comprising a fourth duct coupled between said second duct and said first duct. 11. A fuel-fired furnace coupled to a fuel source and an air source, said furnace comprising: a combustion zone defined within said furnace; a first flow regulation device coupled to the fuel source and selectively operable based on an operation of said furnace; a second flow regulation device coupled to the air source and selectively operable based on an operation of said furnace; and a plurality of burners coupled within said combustion zone, at least one of said plurality of burners comprising: a first duct coupled to the fuel source via said first flow regulation device, said first duct comprises a flame regulation device coupled to a downstream end of said first duct, said first duct configured to channel a fuel flow into said furnace; a second duct extending through said first duct, said second duct coupled to the air source via said second flow regulation device and configured to channel a first air flow into said furnace at a first predetermined velocity when the fuel flow is substantially prevented from being channeled through said first duct by said first flow regulation device; a third flow regulation device coupled to the air source and selectively operable based on an operation of said furnace; and at least one third duct substantially concentrically-aligned with and radially outward from said first duct, said at least one third duct coupled to the air source via said third flow regulation device and configured to channel a second air flow into said furnace at a second predetermined velocity that is different than the first predetermined velocity, wherein the first and second air flows facilitate substantially homogeneous mixing of a far field and a near field. 12. A fuel-fired furnace in accordance with claim 11 further comprises a fuel injector coupled downstream from said combustion zone. 13. A fuel-fired furnace in accordance with claim 11 further comprising an air injector coupled downstream from said combustion zone. 14. A fuel-fired furnace in accordance with claim 11 further comprising a velocity regulation device coupled in flow communication with said second duct and the air source. 15. A fuel-fired furnace in accordance with claim 11 wherein said at least one burner further comprises a fourth duct coupled between said second duct and said first duct. 16. A fuel-fired furnace in accordance with claim 11 further comprising a control system operatively coupled to said first flow regulation device, said second flow regulation device, said third flow regulation device, said control system configured to: channel the second air flow to said third duct at the second predetermined velocity; channel the first air flow to said second duct at the second predetermined velocity during a first mode of operation of said furnace, the first mode of operation substantially preventing the fuel flow from being channeled through said first duct; discontinue the first air flow to said second duct during a second mode of operation of said furnace; and channel the fuel flow to said first duct during the second mode of operation, the second mode of operation substantially preventing the first air flow from being channeled through said second duct.
