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.

An oven is provided, which includes a domed ceiling, a baking stone located below the domed ceiling, a cooking chamber between the domed ceiling and the baking stone, a front opening that provides access to the cooking chamber for food and utensils, a combustion chamber adjacent to, and at least partially below, the cooking chamber, and a rear opening that provides access to the combustion chamber.

A low-smoke carbon furnace including an outer casing, a removable liner, and an annular interlayer is provided. The removable liner is disposed in the outer casing. The removable liner is provided with a combustion chamber therewithin. The removable liner includes multiple secondary air inlets disposed on an upper side wall of the removable liner. The annular interlayer is disposed between the outer casing and the removable liner. A bottom end of the outer casing is provided with interlayer air inlets that communicate with the annular interlayer. Oxygen enters the annular interlayer via the interlayer air inlets, and thereafter enters the combustion chamber of the removable liner via the secondary air inlets to facilitate secondary combustion in the combustion chamber.

An oven is provided, which includes a domed ceiling, a baking stone located below the domed ceiling, a cooking chamber between the domed ceiling and the baking stone, a front opening that provides access to the cooking chamber for food and utensils, a combustion chamber adjacent to, and at least partially below, the cooking chamber, and a rear opening that provides access to the combustion chamber.

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.

An outdoor cooking oven comprises a reconfigurable heat deflector system and independently-controllable air vents that enable the cooking oven to be configured for various cooking methods, such as low and slow cooking or grilling. At least first and second shelves are mounted within a cooking chamber with the second shelf positioned beneath the first shelf. A heat deflector system disposed on the second shelf comprises at least first and second heat deflector elements that are removable from the cooking chamber to enable a user to reconfigure the heat deflector system to vary indirect heating of food items disposed on the first shelf. At least first and second air vents disposed in a bottom side of the exterior encasement beneath the cooking chamber are independently controllable to allow at least first and second airflows from the vents to be independent varied.

The present application relates to improvements to granular fuel burning boilers such as wood pellet boilers and burners therefor. In particular, there is disclosed a wood pellet boiler having a combustion chamber, wherein an access door for said combustion chamber comprises a wood pellet burner assembly mounted on the interior side thereof. In this way, the wood pellet burner assembly is movable from and into the combustion chamber of the wood pellet boiler when the access door is opened and closed, respectively.

A burner for burning fuels and modular heat utilizing appliances therefor. The burner includes a fuel holder, an outer wall surrounding the fuel holder and defining a combustion chamber, and optionally, a second wall surrounding the outer wall. Air is inducted from an inlet which may be an ash pan pivotally coupled to the outer wall at the bottom to open the combustion chamber. Supplementary combustion air is conducted to just above the fuel holder by the outer wall. Additional supplementary combustion air is conducted to just above the fuel holder by the second wall. The burner may include a pivotally mounted cooking grate and a pivotally mounted solid cover for closing the combustion chamber, and supporting legs. Modules individually yet replaceably attachable to the burner include a closed or open cooker, a smoker, a space heater, and a pyrolyzer.

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.
