- a bottom panel 36 extends across the cylindrical wall 30 below the upper end 34.
- the bottom panel 36 may be attached to the cylindrical wall 30 in other ways such as braising or high-temperature adhesives, in the illustrated example the bottom panel is spot welded to the cylindrical wall.
- the wall 30 of the illustrated example has an outer diameter of about 10.75 inches, a height of about 6.25 inches, and is made from 20 gauge steel sheet.
- the bottom panel 36 of the illustrated example is made from 16 gauge steel sheet.
- Racetrack-shaped holes or openings 40 extend through the cylindrical wall or shell 30 below the bottom panel 36, allowing air to circulate below the bottom panel.
- Other holes or orifices 42 extend through the cylindrical wall 30 above the bottom panel 36, providing an air passage to feed combustion as described in detail below. As shown in Fig. 2, these other holes 42 above the bottom panel may have decorative shapes, such as a trade name, or trademark.
- the holes 42 may have other flow areas, in the illustrated example, the holes have a total flow area of about 2.86 square inches.
- Figs. 4-6 illustrate the upper body 22.
- the upper body 22 comprises an outer cylindrical wall or enclosure 50 having a flange or rim 52 extending radially inward from an upper end 54.
- An inner cylindrical wall 56 is positioned concentrically inside the outer cylindrical wall as shown in Fig. 5.

- a narrow elongate hole or other marker 66 extends through the inner cylindrical wall 56 to indicate a level to which the burn chamber should be filled with biomass fuel pellets.
- Circular openings or ports 70 are provided through the inner cylindrical wall 56 to allow air to escape from an annular passage 72 formed between the inner and outer cylindrical walls 56, 50, respectively, and into the burn chamber.
- the outer cylindrical wall 50 of the illustrated example has an outer diameter of about 13.5 inches, a height of about 7.0 inches, and is made from 20 gauge steel sheet.
- the inner cylindrical wall 56 of the illustrated example has an outer diameter of about 12.125 inches and is made from 20 gauge steel sheet.
- the grate 60 of the illustrated example is replaced with a permeable plate such as described below with respect to Figs. 8-14.
- the openings 70 may have other flow areas, in the illustrated example, the openings have a total flow area of about 7.46 square inches.

- a lower end 74 of the outer wall 50 extends below the inner cylindrical wall 56 and grate 60, forming a recess sized for receiving the flange 32 at the upper end 34 of the base 24 to retain the upper body 22 on the base during use.
- the recess has a height of about 0.625 inches.
- the grate 60 covers a bottom end of the annular passage 72. Because the grate 60 rests on the upper flange 32 of the base 24 in use, very little air enters directly into the bottom of the annular passage 72 in use. Circular openings or apertures 80 are provided through the outer cylindrical wall to allow air to enter the annular passage.
- the openings 80 may have other flow areas, in the illustrated example, the openings have a total flow area of about 8.51 square inches.

- a user positions the base 24 on a suitable surface and orients the base, so the flange faces upward.
- the user orients the upper body 22, so the grate 60 faces downward and sets the grate on the flange 32 of the base 24, so the flange is received in the recess of the upper body.
- Biomass fuel pellets are loaded into the burn chamber 64 to the narrow slot 66 indicating the fill level previously described.
- the biomass fuel pellets are ignited using suitable conventional means. As the burning pellets heat air inside the burn chamber 64, air is drawn through the holes 40 above the bottom panel 36 of the base 24 and through the grate 60 to feed the fire as shown in Fig. 7.
- the cumulative area of the holes 40, 42 above the bottom panel 36 of the base 24 is less than the cumulative size of the openings in the grate 60.
- the holes 40 in the base 24 control airflow through the grate 60.
- air exiting the annular passage 72 through the holes 70 in the inner cylindrical wall 56 is warmed as it rises through the annular passage to reduce inefficiencies resulting from cool air entering the burn chamber.
- the air entering the burn chamber 64 from the annular passage 72 provides additional oxygen to the gases above the burning pellets, allowing those gases to be burned more thoroughly to improve the efficiency of the burn and reduce emissions from the fire.
- the flange 52 at the upper end of the burn chamber 64 directs air rising along the inner cylindrical wall 56 inward toward the center of the fire to further improve the secondary emissions burn. Ash falls onto the bottom panel 36 of the base 24 for disposal after the apparatus 22 cools.

- the recess has a height of about 0.625 inches.
- Racetrack-shaped openings or apertures 180 are provided through the outer cylindrical wall to allow air to enter the annular passage.
- the openings 180 may have other flow areas, in the illustrated example, the openings have a total flow area of about 18.60 square inches.
- the cylindrical wall 130 of the base 124 is sized to be received in the upper body 122, so the apparatus 120 can be arranged to take less space during storage and transport.
- the upper body 122 and the base 124 are made from stainless steel or galvanized metal.
- the apparatus 120 of the second configuration is used similarly to the apparatus 20 of the first

Some of the air entering the annular passage 172 through the openings 180 in the outer wall 150 of the upper body 122 passes into the burn chamber 164 near the plate 190 to provide additional oxygen for the burning pellets. Further, air passes through openings 144 in addition to openings 140 and 142 to provide additional airflow. In contrast to the first configuration, the holes 192 in the plate 190 in the second configuration limit air passing through the plate.
- biomass fuels other than wood pellets may be burned in the apparatus 20, 120 of the first and second
- Apparatus 20, 120 described above provide several benefits. These benefits include producing very little smoke, portability, requiring no power, reduced residual ash, and/or producing an aesthetically pleasing flame.
- the configurations of the apparatus 20, 120 provide for efficient burning of wood pellets in the burning chamber.
- Apparatus 20, 120 described above may operate on natural airflow only, eliminating a need for a fan or a blower to enhance portability and to eliminate a need for a power source.
- Apparatus described above also produce very low particulate emission levels and little airborne ash.
- the plate 190 of the second configuration reduces warping under high temperatures compared to the grate 60 of the first configuration.
- the plate 190 is also less
- the plate 190 also improves wind resistance.
- the openings 194 immediately above the plate 190 assist in igniting fuel when fuel is added to the apparatus 120. As will be appreciated by those skilled in the art, the placement of the openings 194 assists primary combustion, enhancing upward airflow toward the secondary combustion ports 170, which provides an even burn pattern at the top of the apparatus 120. Because the openings 194 enter the burn chamber 164 just above the plate 190, they ensure a cleaner burn during the latter third of the burn by enhancing combustion above the pellets.
- the cylindrical bases 24, 124 of the first and second configurations provide stability to the apparatus 20.
- the cylindrical bases 24, 124 also shield the bottom of the grate 60 or plate 190 to prevent contact and reduce an opportunity for users to be burned.
- the bases also protect the burn chambers from downdraft, which may starve the fire and result in smoke.
- the burn chamber 164 of the second configuration is larger than the chamber 64 of the first configuration.
- the increased volume is accomplished by increasing the height and diameter of the chamber 164.
- Increasing chamber size permits a larger volume of pellets to be loaded, which increases burn time.
