A stove using biomass pellets as fuels is disclosed herein, comprising a stove body that comprises a firebox, at least one hopper, and a feed tube, wherein the at least one hopper is connected to the firebox via the feed tube, and fuels contained inside the at least one hopper can enter the firebox along the feed tube under gravity. The stove has a simple structure and removes any mechanically or electrically controlled feeding system by feeding the firebox using gravity of the fuels, therefore lowers the cost.

Embodiments are directed to smoking food in an outdoor grill using a customized smoking routine. In one scenario, an electronic controller of an outdoor grill receives an input to initiate smoke generation according to a specified smoke generation pattern, including: adding a specified amount of combustible pellets to a combustion area within the outdoor grill, such that the combustible pellets begin to burn, measuring a current internal temperature of the outdoor grill and, if below a threshold value, adding a specified amount of additional combustible pellets to the combustion area sufficient to raise the temperature to another threshold value, allowing the internal temperature to cool a temperature below the first threshold value and, upon determining that the temperature of the outdoor grill has cooled below the first specified threshold value, adding additional combustible pellets to the combustion area sufficient to raise the temperature to at least the second threshold value.

A floor and an upright sidewall formed from two vertically coaxial components, each component having a floor baffle with a plurality of floor openings defined therein, each floor retained within a respective upright sidewall with a plurality of sidewall openings defined therein. The floor openings and the sidewall openings cooperate between the two coaxial components such that flow of gases through the floor and upright sidewall of the baffle structure is controlled by rotation of the two vertically coaxial components relative to one another.

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, using biomass pellets as fuels, includes: a stove body that includes a firebox; at least one hopper; and at least one feed tube extending between the at least one hopper and the firebox; and at least one control lever laterally disposed on the at least one feed tube; wherein, fuels within the at least one hopper enter the firebox along the at least one feed tube under gravity when the at least one control lever is in a second position.

A heater may include a combustion chamber configured to burn pellets, the combustion chamber comprising a first barrier; a pellet hopper configured to contain the pellets, the pellet hopper comprising a second barrier; a ventilated chamber between the combustion chamber and the pellet hopper, the ventilated chamber being enclosed by: the first barrier; the second barrier; and one or more surfaces comprising one or more orifices allowing air to pass through the ventilated chamber; a flue for carrying heat from the combustion chamber; and a heat deflector disposed on the flue to deflect heat in a radial direction.

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.
