The present disclosure relates to a non-electric, multifunctional, configurable pellet-burning system for domestic and industrial use, which has a removable burner and an inclined hot gas outlet duct that connects said burner of the system with a heat accumulator tank that operates as a second combustion chamber and as a particle filter.

Disclosed is a particle heating landscape furnace, which includes a combustion device. The combustion device includes a vertically arranged cover pipe, a grid and a combustion assembly. The combustion assembly has a feed chamber, a flame outlet and a flame outlet opposite to the flame outlet. A feed chamber is arranged obliquely, the flame outlet and the discharge port are both connected with the feed chamber, and the cover pipe is arranged on a periphery of the flame outlet, the grid is arranged on an outer side of the discharge port.

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 pellet hopper for use in a pellet grill includes a first bottom panel, a second bottom panel, and a third bottom panel. Each bottom panel has an inner edge that partially defines a pellet evacuation opening. The first, second, and third bottom panels form respective first, second, and third nonzero angles relative to a horizontal plane. In this way, each bottom panel tilts downward toward the pellet evacuation opening.

Combustion appliances for providing heat for cooking meats and other foods are provided. The appliances are self-stoking, in that they do not need to be repeatedly re-filled with more fuel periodically, such as during an 18-hour slow cook procedure. A venturi assembly is provided which consists of a venturi duct and baffle, which creates a higher flow, lower pressure region within the venturi assembly, which gases mix with spent combustion gases to provide a more uniform temperature output.

A solid pellet fueled heater having a base unit with forced air blowers and a dual tube chimney structure is disclosed. The dual tube chimney structure may be used to warm incoming air for distribution around the heater. The pellet heater may also include a dual auger system and multi/high speed auger motor. The dual auger may include first and second auger blades mounted on a single auger shaft having blade pitches configured to convey solid fuel in opposite directions.
