초록 ▼

An apparatus includes a furnace structure defining a reaction zone. A burner structure communicates with the reaction zone through a burner port. The burner port is centered on a burner axis and has a radius. A fuel inlet structure communicates with the reaction zone through a fuel port. The fuel port is centered on a fuel port axis that is spaced radially from the burner axis a distance within a range from about twice the radius to about six times the radius. The fuel port axis is skewed relative to the burner axis to direct the fuel emerging from the fuel port to flow into the reaction zone along a spiral flow path.

1. An apparatus comprising:a wall structure defining a reaction zone, including a wall facing into said reaction zone; a burner structure extending through said wall to communicate with said reaction zone through a burner port facing into said reaction zone from said wall, said burner port being centered on a burner axis; and a fuel inlet structure extending through said wall to communicate with said reaction zone through a fuel port facing into said reaction zone from said wall, said fuel port being centered on a fuel port axis that is skewed relative to said burner axis in a plane parallel to said burner axis. 2. An apparatus as defined in claim 1, wherein said fuel port axis is skewed relative to said burner axis an amount within a range of about 10 degrees to about 30 degrees.3. An apparatus as defined in claim 2, wherein said fuel port axis is skewed relative to said burner axis by about 20 degrees.4. An apparatus as defined in claim 1, wherein said fuel port is skewed relative to said burner port such that fuel emerging from said fuel port follows a spiral flow path about said burner axis.5. An apparatus as defined in claim 4, further comprising a second fuel port, and said second fuel port is skewed relative to said burner port in a plane parallel to said burner axis such that additional fuel emerging from said second fuel port follows a second spiral flow path about said burner axis opposite said spiral flow path.6. An apparatus comprising:a wall structure defining a reaction zone, including a wall facing into said reaction zone; a burner structure extending through said wall to communicate with said reaction zone through a burner port facing into said reaction zone from said wall, said burner port being centered on a burner axis and having a radius; and a fuel inlet structure extending through said wall to communicate with said reaction zone through a fuel port facing into said reaction zone from said wall, said fuel port being centered on a fuel port axis that is spaced radially from said burner axis a distance within a range from about twice said radius of said burner port to about six times said radius of said burner port; wherein said fuel port axis is skewed relative to said burner axis in a plane parallel to said burner axis. 7. An apparatus as defined in claim 6, wherein said fuel port axis is skewed relative to said burner axis an amount within a range from about 10 degrees to about 30 degrees.8. An apparatus as defined in claim 7, wherein said fuel port axis is skewed relative to said burner axis by about 20 degrees.9. An apparatus as defined in claim 6, wherein said fuel port is skewed relative to said burner port such that fuel emerging from said fuel port follows a spiral flow path about said burner axis.10. An apparatus as defined in claim 9, further comprising a second fuel port, and said second fuel port is skewed relative to said burner port in a plane parallel to said burner axis such that additional fuel emerging from said second fuel port follows a second spiral flow path about said burner axis opposite said spiral flow path.11. An apparatus comprising:a furnace structure defining a reaction zone; a burner structure communicating with said reaction zone through a burner port, said burner port being centered on a burner axis and having a radius; a fuel inlet structure communicating with said reaction zone through a fuel port, said fuel port being centered on a fuel port axis that is spaced radially from said burner axis a distance within a range from about twice said radius to about six times said radius of said burner port; a second burner structure communicating with said reaction zone through a second burner port, said second burner port being centered on a second burner axis and having a second radius; and a second fuel inlet structure communicating with said reaction zone through a second fuel port, said second fuel port being centered on a second fuel port axis that is spaced radially from said second burner axis a second distance, said second distance being within a range from about twice to about six times said second radius of said second burner port; wherein said burner axes are spaced from each other an amount that is greater than the sum of said distances; and wherein said fuel port axis is skewed relative to said burner axis in a plane parallel to said burner axis. 12. An apparatus as defined in claim 11, wherein said fuel port axis is skewed relative to said burner axis an amount within a range from about 10 degrees to about 30 degrees.13. An apparatus as defined in claim 12, wherein said fuel port axis is skewed relative to said burner axis by about 20 degrees.14. An apparatus as defined in claim 11, wherein said fuel port is skewed relative to said burner port such that fuel emerging from said fuel port follows a spiral flow path about said burner axis.15. An apparatus as defined in claim 14, further comprising a second fuel port, and said second fuel port is skewed relative to said burner port in a plane parallel to said burner axis such that additional fuel emerging from said second fuel port follows a second spiral flow path about said burner axis opposite said spiral flow path.
