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 cooking system having a pellet fueled cooking chamber, a fire chamber held in a fixed relationship with respect to the cooking chamber, and a user adjustable port that selectively allows fluid communication from the fire chamber to the cooking chamber.

A multi-leveled cooking apparatus is an apparatus that is used to prepare food. The apparatus includes an enclosure, a heat source, at least one convectively-heated cooking mechanism, a radiatively-heated cooking mechanism, a first duct, and a second duct. The enclosure is used as a structural base to mount the aforementioned components, and to maintain and regulate temperature fluctuations. The heat source sends hot air through the first duct and the second duct to heat the at least one convectively-heated cooking mechanism. The heat source is also in contact with the radiatively-heated cooking mechanism. A series of tubes within the enclosure provide adequate dispersal of combustible gaseous material, and an ignition starter allows the user to ignite the gas contained within the present invention. Removable grates are arranged at various heights within the enclosure, allowing customization of the size of the working space as well as improving accessibility for sanitization.

A fuel burner and optional modular heat utilizing appliances capable of exploiting heat from the fuel burner are shown and described. The burner includes a fire box including a fuel holder, a surrounding inner housing, and an outer shroud surrounding the inner housing. A plurality of air openings including flow adjusters admit air to the fire box. The inner housing and outer shroud are configured to supply air for secondary combustion of the exhaust. The burner may include a fan for forced air induction, and a fuel chute having a slidable closure for recharging the fuel holder from outside. At least one modular heat utilizing appliance may have thermal insulation for retaining heat.

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 biomass pellet combustion system includes a primary burn chamber, a coal burn chamber, and a gas burn chamber. The primary burn chamber is configured to receive pellets from a drop tube of the biomass pellet combustion system. The coal burn chamber is configured to receive coals from the primary burn chamber. The gas burn chamber is configured to receive combustible gases from both the primary burn chamber and the coal burn chamber, wherein a secondary combustion process converts secondary combustion air and the combustible gases into exhaust gases in the gas burn chamber.

Disclosed is a fireplace which includes a firebase, a primary combustion zone with a first air supply unit, a secondary combustion zone, and an exhaust flue. The fireplace place also includes a charcoal/reduction layer which forms between the primary combustion zone and the secondary combustion zone, the arrangement and construction being such that the gases and/or particulate matter produced from the pyrolysis and/or combustion of the biomass fuel in the primary combustion zone have to pass over, or through, the charcoal/reduction layer prior to entering the secondary combustion zone and/or the exhaust flue. The fireplace also includes a second air supply unit for introducing heated secondary air into, or adjacent to, the secondary combustion zone, the arrangement and construction being such that the secondary air passes through (or adjacent to the region of) the charcoal/reduction layer to thus heat the secondary air.
