A pellet stove having a combustion assembly housing. Located within the housing in a vertical array are a primary combustion chamber, a secondary combustion chamber located below the primary combustion chamber, and an ash receptacle located below the secondary combustion chamber. The primary combustion chamber communicates with the secondary combustion chamber, and the secondary combustion chamber communicates with the ash receptacle. A pellet feed housing is located above the primary combustion chamber and has a feed plate configured to feed pellets directly into the primary combustion chamber along an inclined path. Air intake ducts communicate ambient air with the interior of the housing. The primary combustion chamber communicates with a combustion gas conduit that conducts combustion gases along an upwardly extending tortuous path to an exhaust stack to provide heating. A pivotal, latchable door is attached to the front of the combustion assembly housing.

A wood pellet combustion container for a fireplace. The wood pellet combustion container comprises a housing having a base and a sidewall forming an interior volume having an open upper end. The housing further includes a platform that is slidably disposed within the sidewall at the open upper end such that it can be removed from the housing. The platform includes a plurality of apertures and a handle disposed thereon, wherein the platform receives burning wood pellets. The sidewall further includes a drawer slidably mounted below the platform, wherein the drawer receives wood pellet ashes that fall through the plurality of apertures. The wood pellet combustion container is placed within a fireplace, such that heat is generated from burning wood pellets placed on the platform.

Provided is an air cooled combustion furnace system to effectively operate a combustion furnace for generation of heat energy via combustion of a solid fuel so as to optimize thermal efficiency. The combustion furnace system includes a combustion body structure provided with a hopper and having a combustion space for production of heat energy via combustion of a solid fuel, a cooling device integrally formed in multiple layers with the combustion body structure to cool the combustion body structure via distribution of air, a negative pressure induction device to create a negative pressure within the combustion body structure by suctioning air, a fuel supply device, a grate device constructed by coupling a plurality of grate segments to one another and serving to support the solid fuel being combusted, and a clinker removal device to remove clinkers generated during combustion of the solid fuel from the grate device.

A solid fuel burning cabinet circular heating appliance achieves improved emissions performance by providing a secondary air combustion path that preheats secondary combustion air. The firebox is selectively insulated such that areas of the firebox that do not preheat combustion air retain heat in the firebox while areas of the firebox that transfer heat into the combustion air transfer heat through the firebox into the incoming combustion air. The exhaust air path from the firebox to a chimney is also uninsulated to allow relatively quick heat transfer into a room in which the appliance is installed.

A fire pit includes an upper portion having an inner chamber wall defining a combustion chamber with a fuel grate retained therein, and a lower portion having a base member defining an ash receptacle. The upper and lower portions separably mate together such that ash falling through the fuel grate is received in the ash receptacle when the upper and lower portions are fitted together.

A heat deflector is disclosed that includes a first portion having a first outer edge and a center and a first surface extending from the first outer edge to the center of the first portion. The first surface sloping downward from the first outer edge toward the center of the first portion. The heat deflector further includes a second portion having an inner edge and an outer edge. The inner edge of the second portion is adjacent to the first outer edge of the first portion. The heat deflector further includes a third portion having a third outer edge and a third inner edge and a second surface extending from the third outer edge of the third portion to the third inner edge of the third portion. The second surface sloping downward from the third outer edge of the third portion to the third inner edge of the third portion.

The invention relates to a device for, in particular low-emission, burning of (solid) fuels, in particular with visible fire, preferably a fireplace and/or stove and/or stove fireplace, comprising a section for receiving a bulk material, preferably an air turbulence chamber, which is designed for the purpose of guiding an air mass flow in at least one direction through the bulk material; and receiving the bulk material in such a way that the air mass flow experiences turbulence through the bulk material, the turbulence slowing down the air mass flow along the at least one direction, and making the air mass flow slowed down in this way available for burning of the (solid) fuel, in particular such that the burning is carried out with little particulate matter.

A modular flue adapter system and method is described to accommodate a conduit for exhaust between a firebox and a firebox flue, wherein the firebox is inserted into a firebox opening, by providing an offset distance and/or direction between the exhaust of the firebox and the firebox flue.
