Disclosed is a stove (1) arranged for combusting granular material. The stove (1) comprises a granular material combustion area (5) including a bottom combustion surface (6) and granular material feeding means (15) arranged for feeding granular material up into the granular material combustion area (5) from a granular material storage (16) arranged beneath the granular material combustion area (5), wherein the granular material feeding means (15) comprises a curving auger (21). Furthermore, a use of a stove (1) is disclosed.

A pellet stove includes a hopper for storing pellets, a basket for receiving the pellets by gravity, a duct for conveying combustion air to the basket, and a conduit for conducting heated air away from the basket. The position of the basket is adjustable, such as by raising and lowering it, or by rotating it, so as to control the number of pellets in the area of most intense combustion. One or more optional burn plates, positioned below the basket, provide platforms on which pellets falling through the basket can burn down to a smaller size. The pellet stove requires no external source of power. The stove so constructed enables quiet, efficient and clean burning of the pellets.

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.

Disclosed is a combi stove (1) arranged for combusting both logs and granular material. The combi stove (1) comprises a common combustion chamber (2) arranged so that both the logs and the granular material may be combusted in the common combustion chamber (2). The combi stove (1) further comprises ash collecting means (3) arranged under the combustion chamber (2) and a front aperture (4) through which logs may be placed in the combustion chamber (2). Also the combi stove (1) includes a granular material combustion area (5) arranged in the combustion chamber (2), wherein the granular material combustion area (5) comprises a bottom combustion surface (6) including bottom airflow apertures (7) arranged to enable an airflow to the granular material during a combustion of the granular material in the granular material combustion area (5), wherein the granular material combustion area (5) is at least partly surrounded by a granular material area sidewall (8) comprising sidewall airflow apertures (9) arranged to enable an airflow to flue gasses generated during a combustion of the granular material in the granular material combustion area (5), and wherein at least a part of the granular material area sidewall (8) is releasable from the granular material combustion area (5). Furthermore, a use of a combi stove (1) is disclosed.

A fire pit includes an engine having at least one wall defining an inner chamber. At least one primary air aperture is defined through the inner chamber wall at a first, lower level, and at least one secondary air aperture is defined through the inner chamber wall at a second, upper level. A fuel grate is supported within the inner chamber at a level between the lower level and the upper level.
