An oven for cooking foods includes a housing having a fire chamber and a cooking chamber disposed generally above the fire chamber. A vessel is receivable in the fire chamber and is adapted to hold combustible material therein to generate heat and smoke for cooking food in the cooking chamber. A blower is mounted on the housing. The blower is selectively operable to move air. A tube is attached to an outlet of the blower and extends into the fire chamber such that when the vessel is received in the fire chamber the tube extends to a position adjacent the vessel so that air from the blower is blown directly into the vessel without first passing a heating element. The oven does not require supplemental heat from a burner or similar heating element.

The wood heating device, such as a stove or a wood-burner, includes a combustion chamber defined by a metal combustion space having an intake. The chamber is equipped with a closing mechanism of the retractable type, and at least one distinct oxidant air inlet orifice. The combustion space is housed in a metal outer casing. The outer casing defines with the combustion space at least one reserve of preheated air and an oxidant air duct. An outside-air supply opening is made in the outer casing and is arranged laterally to the intake. The reserve of preheated air bypasses the combustion space by at least one side starting from the outside-air supply opening.

Exhaust sensors for use with residential solid fuel-burning appliances are disclosed. In one example, a sensor apparatus includes an optical sensor, a lens, and first and second light sources positioned adjacent to the optical sensor. The first light source is configured to emit a first light signal towards a target area of an exhaust gas stream. The second light source is configured to emit a second light signal towards the target area. The optical sensor is configured to detect a light signal comprising at least one of a reflected portion of the first and second light signals and a diffracted portion of the first and second light signals. The sensor apparatus also includes a processor configured to determine a concentration of smoke particles in the exhaust gas stream based on the detected light signal.

A wood-burning stove includes a first baffle spaced apart from the stove's front wall and extending from the stove's floor towards its ceiling to a height in a range of (0.65-0.75) of the stove's internal height. An air intake chamber is defined between the stove's front wall and first baffle. A firebox is defined between the first baffle and the stove's back wall. A second baffle is coupled to the stove's back wall at a position thereon below the stove's flue port. The second baffle extends from the back wall towards the first baffle to a second baffle depth of (0.7-0.85) of the stove's firebox depth. The second baffle terminates at an outboard edge that is spaced apart from the stove's ceiling to define a flow area in a range of 0.5-1.0 times a cross-sectional area of the flue port.

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.

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 stove including spiraling walls to create multiple vertical inlets, spiraling layers of spaces that can self-draw and self-heat the air from outside of the stove into the burn zone, and a rim that covers the top area of the spiraling walls and leaves an opening above the fire. From burning, a convection draft draws air from the side-environment of the stove through the vertical inlets to circulate in the spiraling layered space, and to supply to the fire horizontally. The circling of air will be heated by the fire through conduction and irradiation. This design enables extra heated air directly for an enhanced primary burn. The stove can include side walls of different profiles, e.g., straight, tilted and curved walls and different spiraling profiles of spiraling layered spaces, e.g., linear, exponential, and exponential-polynomial.

A wood stove monitoring and control device can include a mounting flange mountable to a chimney exhaust pipe of a wood stove. The device can include a ring removably mountable on top of the mounting flange, where the flange is suitably positioned vertically along the exhaust pipe so that the ring is positioned at least partially above an end of the exhaust pipe. The device includes an optical beam source disposed on the ring, and which generates and outputs an optical beam. The device includes an optical sensor positioned on the ring opposite the optical beam source to detect the optical beam output by the optical beam source as the optical beam passes through smoke exhausted by the wood stove through the exhaust pipe. The device can include a temperature probe disposed on the ring to measure a temperature of heat exhausted by the wood stove through the exhaust pipe.

A multi-purpose grill is described. The grill may include a housing comprising at least one housing sidewall defining a housing interior. The at least one housing sidewall may include a firebox door and a firebox opening leading to the housing interior. The grill may also include a pan that may be located in the housing interior, a cooking grate that may be located above the pan, a removable sleeve and a removable lid that may be located above the cooking grate. The pan may sit on one or more removable rods.
