Burner housing for a pellet grill
The invention relates to a burner housing for a pellet grill having two or more elongated apertures configured to have a first end with an adjacent first width and a second end with an adjacent second width, the adjacent second width relatively greater than the adjacent second width. The burner housing generates an air vortex when in burner operation in such a manner as to provide relatively more air movement in an area somewhat distal to the burner, thereby retaining an optimal amount of ash during lengthy cooking cycles while also providing optimal fuel-to-air characteristics.
1. A burner housing for a pellet grill comprising:
a first end comprising a first end opening;
a second end located opposite the first end; and
a surface extending from the first end to the second end and having two or more apertures disposed thereon, each of the two or more apertures having a first width proximate to the first end that is greater than a second width proximate to the second end;
wherein the two or more apertures are configured to generate air movement within an interior region defined by the surface, the air movement within the interior region being greater proximate to the first end than proximate to the second end.
2. The burner housing for a pellet grill of claim 1 , the second end further comprising a second end opening.
3. The burner housing for a pellet grill of claim 1 , wherein the two or more apertures are configured to generate an air vortex within the interior region.
4. The burner housing for a pellet grill of claim 1 , wherein the surface comprises a cylindrical surface.
5. The burner housing for a pellet grill of claim 1 , wherein each of the two or more apertures is parallel to a longitudinal axis of the burner housing.
6. The burner housing for a pellet grill of claim 1 , further comprising two or more directional fins disposed on the surface.
7. The burner housing for a pellet grill of claim 6 , wherein each directional fin in the two or more directional fins is adjacent to a corresponding aperture in the two or more apertures.
8. The burner housing for a pellet grill of claim 6 , wherein each directional fin in the two or more directional fins is configured to direct air through a corresponding aperture in the two or more apertures and into the interior region.
9. The burner housing for a pellet grill of claim 1 , wherein at least one of the two or more apertures comprises a triangular aperture.
10. The burner housing for a pellet grill of claim 1 , wherein at least one of the two or more apertures tapers from the first width proximate to the first end to the second width proximate to the second end.
11. The burner housing for a pellet grill of claim 1 , further comprising one or more additional apertures disposed on the surface.
12. A burner housing for a pellet grill comprising:
a first end;
a second end; and
a surface extending from the first end to the second end and having two or more apertures disposed thereon, each of the two or more apertures having a first width proximate to the first end that is greater than a second width proximate to the second end;
wherein the surface and the two or more apertures are configured to direct air exterior to the surface into an interior region defined by the surface and thereby generate air movement within the interior region, the air movement within the interior region being greater proximate to the first end than proximate to the second end.
13. The burner housing for a pellet grill of claim 12 , the first end comprising a first end opening.
14. The burner housing for a pellet grill of claim 12 , the second end comprising a second end opening.
15. The burner housing for a pellet grill of claim 12 , wherein the two or more apertures are configured to generate an air vortex within the interior region.
16. The burner housing for a pellet grill of claim 12 , wherein the surface comprises a cylindrical surface.
17. The burner housing for a pellet grill of claim 12 , wherein each of the two or more apertures is parallel to a longitudinal axis of the burner housing.
18. The burner housing for a pellet grill of claim 12 , further comprising two or more directional fins disposed on the surface.
19. The burner housing for a pellet grill of claim 18 , wherein each directional fin in the two or more directional fins is adjacent to a corresponding aperture in the two or more apertures.
20. The burner housing for a pellet grill of claim 18 , wherein each directional fin in the two or more directional fins is configured to direct air through a corresponding aperture in the two or more apertures and into the interior region.
21. The burner housing for a pellet grill of claim 12 , wherein at least one of the two or more apertures comprises a triangular aperture.
22. The burner housing for a pellet grill of claim 21 , wherein at least one of the two or more apertures tapers from the first width proximate to the first end to the second width proximate to the second end.
23. The burner housing for a pellet grill of claim 12 , further comprising one or more additional apertures disposed on the surface.
24. A burner housing for a pellet grill comprising:
a first end comprising a first end opening and a second end comprising a second end opening;
a cylindrical surface extending from the first end to the second end and having a plurality of apertures disposed thereon, each aperture being parallel to a longitudinal axis of the burner housing and having a first width proximate to the first end that is greater than a second width proximate to the second end; and
a plurality of directional fins corresponding to the plurality of apertures, each directional fin being adjacent to a corresponding aperture and being configured to direct air through the corresponding aperture and into an interior region of the cylindrical surface;
the plurality of elongated apertures and the plurality of directional fins being configured to generate a vortex within the interior region, the vortex narrowing in width from the first end to the second end to thereby retain a portion of particulate matter generated during operation of the pellet grill within an area proximate to the second end.
