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.

An ash remover for removing ashes from a wood burning stove or fireplace includes a housing with top and bottom walls, spaced-apart side walls, a rear wall, and a front door. A fixed gripping handle projects outwardly from the rear wall of the housing. A pivotable gripping handle is mounted to the side walls of the housing of the ash remover. The ash remover may be used in combination with a sifting tool to separate burning embers from ashes prior to removing the ashes from the wood burning stove or fireplace.

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 fire pit a removable fire grate and a removable ash pan. The removable fire grate is positioned within a burn chamber and supports combustible fuel for burning. The removable fire grate includes a plurality of holes sized to permit passage of ash from the combustible fuel, and at least one grip feature sized and shaped to permit a user to remove the removable fire grate from the fire pit by lifting the removable fire grate vertically through the burn chamber. The removable ash pan is positioned within the burn chamber beneath the removable fire grate, and includes, a side wall, a bottom, and at least one grippable surface configured to permit the user to remove the removable ash pan from the fire pit by lifting the removable ash pan vertically through the burn chamber.

A wood stove that includes a hollow cylindrical outer skin with an coaxially aligned, insulated inner fire box. Located below the fire box is a fresh air inlet and an air control valve that controls the flow of fresh air into the stove's primary and secondary chambers. Surrounding the fire box are three longitudinally aligned air conduits that extend from the air inlet to an upper ledge located below a secondary combustion chamber. During use, the fresh air inside the air conduits is heated. Disposed transversely inside the outer jacket and above the primary chamber is a combustor assembly that includes a lower fin plate, a perforated intermediate plate and a perforated upper plate. During use, fuel is added to the fire box which undergoes initial combustion and produces hot gases and fumes that travel upward towards the chamber assembly. The air control valve controls flow of fresh air into the primary chamber only, both chambers, or into only the secondary chamber.

A fire pit a removable fire grate and a removable ash pan. The removable fire grate is positioned within a burn chamber and supports combustible fuel for burning. The removable fire grate includes a plurality of holes sized to permit passage of ash from the combustible fuel, and at least one grip feature sized and shaped to permit a user to remove the removable fire grate from the fire pit by lifting the removable fire grate vertically through the burn chamber. The removable ash pan is positioned within the burn chamber beneath the removable fire grate, and includes, a side wall, a bottom, and at least one grippable surface configured to permit the user to remove the removable ash pan from the fire pit by lifting the removable ash pan vertically through the burn chamber.

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 pellet stove includes: a furnace; a burner disposed in the furnace, a top of the burner being open; and a feed opening provided at a first sidewall of the burner. A through port for air intake and ash falling is provided at an underside of the burner. A grate supporting pellet fuel is provided above the through port. Auxiliary supports for sustaining bottom fire are disposed under the grate. The auxiliary supports are arranged higher than the through port, and the auxiliary supports are located at a side below the feed opening and cover an area not exceeding of the area covered by the grate.

A fire pit includes a plurality of detachable connection mechanisms, a plurality of wall bodies, a pressing frame, and a bearing plate. The wall bodies surround to form a chamber. The two adjacent wall bodies are connected to each other through the detachable connection mechanism. The pressing frame surrounds to form an opening that communicates with the chamber. The pressing frame is located at an upper portion of the chamber and provides a first horizontal force to push against the wall bodies. The bearing plate is adapted to bearing fuel placed in the chamber. The bearing plate is provided with a plurality of through holes that communicate with the chamber. The bearing plate is located at a lower portion of the chamber and provides a second horizontal force to push against the wall bodies.
