Combustible fuel burning stove with pellet adapter
A stove includes a combustion chamber, a fuel grate positioned within the combustion chamber, and a pellet adapter removably positionable on the fuel grate. The fuel grate includes a number of first ventilation holes. The pellet adapter includes a number of second ventilation holes sized and shaped to prevent passage of a fuel pellet. The pellet adapter also includes a raised outer rim and a central protuberance with a height greater than the height of the raised outer rim.
1. A stove comprising:
a combustion chamber;
a fuel grate positioned within the combustion chamber, the fuel grate comprising a plurality of first ventilation holes of a size that permits passage of a fuel pellet;
a pellet adapter removably positionable on the fuel grate within the combustion chamber, the pellet adapter comprising:
a pellet tray comprising a plurality of second ventilation holes sized and shaped to prevent passage of the fuel pellet;
a raised outer rim; and
a central protuberance with a height greater than the height of the raised outer rim.
2. The stove of claim 1 , wherein the pellet adapter further comprises a plurality of indentations.
3. The stove of claim 2 , wherein the pellet tray comprises a handle grippable by a user.
4. The stove of claim 2 , wherein the indentations comprise feet that contact the fuel grate when the pellet adapter is positioned on the fuel grate within the combustion chamber.
5. The stove of claim 2 , wherein when the pellet adapter is positioned on the fuel grate within the combustion chamber, a bottom edge of the raised outer rim contacts the fuel grate.
6. The stove of claim 1 , wherein the central protuberance comprises a lower portion fixedly attached to the pellet tray and an upper portion removably attached to the lower portion.
7. The stove of claim 1 , wherein the central protuberance comprises a plurality of third ventilation holes sized and shaped to prevent passage of the fuel pellet.
8. The stove of claim 1 , wherein the central protuberance comprises a truncated cone.
9. The stove of claim 1 , wherein the pellet tray comprises a truncated cone.
10. The stove of claim 1 , wherein the raised outer rim comprises a plurality of fourth ventilation holes sized and shaped to prevent passage of the fuel pellet.
11. The stove of claim 1 , wherein, when the pellet adapter is positioned on the fuel grate within the combustion chamber, an air gap exists between the raised outer rim and an inner wall of the combustion chamber.
12. A pellet adapter for adapting a wood burning stove to a pellet burning stove, the pellet adapter comprising:
a pellet tray comprising a plurality of ventilation holes sized and shaped to prevent passage of a fuel pellet;
a raised outer rim; and
a central protuberance with a height greater than the height of the raised outer rim, wherein the pellet adapter is removably positionable on a fuel grate of a stove within a combustion chamber of the stove.
13. The pellet adapter of claim 12 , wherein the pellet adapter further comprises a plurality of indentations formed in the pellet tray.
14. The pellet adapter of claim 13 , wherein the indentations comprise feet that contact the fuel grate when the pellet adapter is positioned on the fuel grate within the combustion chamber.
15. The pellet adapter of claim 12 , wherein the central protuberance comprises a lower portion fixedly attached to the pellet tray and an upper portion removably attached to the lower portion.
16. The pellet adapter of claim 12 , wherein at least one of the central protuberance or the raised outer rim comprises a plurality of third ventilation holes sized and shaped to prevent passage of the fuel pellet.
17. The pellet adapter of claim 12 , wherein the central protuberance comprises a truncated cone.
18. The pellet adapter of claim 12 , wherein the pellet tray comprises a truncated cone.
19. The pellet adapter of claim 12 , wherein, when the pellet adapter is positioned on the fuel grate within the combustion chamber, an air gap exists between the raised outer rim and an inner wall of the combustion chamber, and a bottom edge of the raised outer rim contacts the fuel grate.
20. A pellet adapter for adapting a log or stick burning stove to a pellet burning stove, the log or stick burning stove including a combustion chamber with a fuel grate therein, the fuel grate having holes configured to pass air or ash therethrough, the holes having a first width that does not inhibit or prevent passage of a fuel pellet, the pellet adapter comprising:
a pellet tray sized to removably fit within the combustion chamber and comprising a plurality of ventilation holes having a second width smaller than the first width, the second width being sized to inhibit or prevent passage of the fuel pellet; and
a handle on the pellet tray graspable by a user to introduce or remove the pellet tray into the combustion chamber to adapt the stove to a pellet burning stove.
21. The pellet adapter of claim 20 , comprising:
a raised outer rim around the pellet tray having a first height; and
a central protuberance extending from the pellet tray with a second height greater than the first height.
22. The pellet adapter of claim 21 , wherein the handle is formed as at least one of:
an opening in the central protuberance or a graspable handle extending above the pellet tray.
23. The pellet adapter of claim 20 , wherein the pellet adapter further comprises a plurality of indentations formed in the pellet tray that form legs that offset the pellet tray from the fuel grate.
24. A method of adapting a log or stick burning stove to a pellet burning stove, the log or stick burning stove including a combustion chamber with a fuel grate therein, the fuel grate having holes configured to pass air or ash therethrough, the holes having a first width that does not inhibit or prevent passage of a fuel pellet, the method comprising:
grasping a pellet adapter by a handle, the pellet adapter sized to fit within the combustion chamber and having a pellet tray comprising a plurality of ventilation holes having a second width smaller than the first width, the second width being sized to inhibit or prevent passage of the fuel pellet;
introducing the pellet adapter into a top opening of the combustion chamber of the log or stick burning stove; and
adding fuel pellets onto the pellet tray for combustion.
25. The method of claim 24 , wherein introducing the pellet adapter into a top opening of the combustion chamber includes placing the pellet adapter onto the fuel grate, the pellet adapter being offset from the fuel grate to permit air to flow between the fuel grate and the pellet adapter.
