Abstract: A live-fire grill has been developed with a central opening and one or more adjustable accessories. In one example, the central opening is covered by a central grate to provide a more typical grilling experience. In another example, the central grate is raised to prevent food loss down the central opening. Surrounding the central opening is a griddle with an outer periphery defining a retention ledge. The retention ledge serves as a backstop to prevent food falling off the griddle and onto the ground. Attached to the grill is one or more rods holding one or more adjustable accessories. The accessories automatically lock in position and may be adjusted both horizontally and vertically. In one example, the accessory is an adjustable grate with 360 degrees of rotation.

Abstract: The invention relates to a wood pellet stove, comprising a feed device for automatically adding wood pellets in a metered manner from a pellet hopper belonging to the stove. Said pellet hopper having the feed device and a grate is accommodated in a lower, stationary stove part (20), which remains cold and does not become hot during operation. The combustion chamber having a chimney connection is accommodated in an upper stove part (21). The upper stove part (21) is supported on the lower stove part (20) by means of a turntable so that the upper stove part can be swiveled relative to the lower, stationary stove part (20). Thus, the combustion chamber and the viewing window can be swiveled in any desired direction as needed.

Abstract: A charging device for a shaft furnace, in particular for a blast furnace and a cooperating distribution chute are proposed, where the distribution chute has an elongated chute body providing a sliding channel for bulk material and two chute-mounting members attached laterally to either side of the chute body for mounting the distribution chute to the charging device, the charging device including a mechanism for rotating the distribution chute, the mechanism having a rotatable support rotor with two suspension flanges cooperating with the chute-mounting members of the distribution chute for mounting the distribution chute, where each chute-mounting member of the chute includes a hook-shaped portion that forms a suspension hook for mounting the distribution chute to the suspension flanges, each suspension flange in turn has a support configured for engagement with the hook-shaped portion of the chute along a hook engagement direction, and furthermore, each chute-mounting member includes an abutment portion tha

Abstract: A pellet furnace includes a pellet feed assembly, a conveyor assembly, a combustion blower assembly, a baffle assembly, and a control system. The pellet feed assembly includes a distribution tray having a plurality of distribution pins for spreading a mass of pellets over a desired area. The conveyor assembly includes an air distribution plenum and a plurality of grate plates for maintaining a deposited mass of pellets and receiving air from air distribution plenum to facilitate primary combustion of the mass of pellets.

Abstract: According to embodiments of the present invention, a pellet stove includes a firepot assembly with a bottom plate slideable along rails to move between a closed position during combustion in the firepot and an open position during ash removal. According to other embodiments, a firebox or combustion enclosure includes a plurality of airfoils formed on the inner and outer surfaces of the enclosure to facilitate heat exchange between exhaust gases flowing across the inner surface of the enclosure and air blown across the outer surface of the enclosure. According to some embodiments, the airfoils and enclosure are of integral unibody construction. According to yet other embodiments, a user sets parameters via a wall control unit, and a stove control unit receives the parameters and automatically controls fuel feed rate, ignition, convection blower, combustion blower, and/or firepot cleaning based on the one or more parameters.

Abstract: A burner system is described for burning granular pellets and similarly sized solid biomass heating fuel, e.g. wood pellets. It includes an air tight fire chamber having an exhaust outlet in an upper region thereof and a burner (10) in the bottom thereof for converting the solid fuel to fuel gases and ash in the presence of a limited air supply and combusting the gases formed. The burner comprises upright co-axial inner (12) and outer (11) cylindrical walls providing a confined central gasification/combustion chamber surrounded by an annular combustion air manifold (15). The annular combustion air manifold (15) is closed at the top and bottom with an air inlet (16) in the outer wall and a plurality of spaced aperatures (17) arranged in upward rows in the inner cylindrical wall providing air inlets from the combustion air manifold to the combustion zone of the chamber. A grate at the bottom of the gasification/combustion chamber holds the solid fuel while allowing ash to pass through the grate.

Abstract: A furnace for solid fuels is especially for pellets. This furnace includes a combustion chamber, a holder pan for the combustion material positioned in the combustion chamber, and a combustion material transport device located between the holder pan and a fuel container for combustion material. The combustion chamber is surrounded by a convection space, which is closed off towards the outside by a convection mantle, with a blower arranged between the ambient air and the convection space, if necessary. A flue gas blower is arranged between the combustion chamber and a flue gas line. A flue gas channel is arranged in front of at least one rear wall of the combustion chamber on the side facing away from the combustion chamber. This channel extends over at least part of a width and a height of the combustion chamber.

Abstract: A heater is disclosed for burning combustible particulate fuels. The fuels are delivered to an internal retort at a constant rate. They are burned at an open end of the retort with the aid of a primary air supply manifold that surrounds the open end of the retort and directs primary combustion air into the particulates at the open retort end. Secondary combustion air is directed through an annular air supply manifold situated above the open retort end. The hot exhaust gases pass upwardly through a combustion chamber and subsequently downwardly through an exhaust gas plenum to an exhaust gas discharge. Flow of the combustion air and exhaust gases is induced by a vacuum blower mechanism by which a reduced pressure is produced within the combustion chamber to draw air through the primary and secondary air supply manifolds. The exhaust gases drawn off by the vacuum mechanism are pressurized on a discharge side of the vacuum mechanism.

Abstract: A furnace for wood log fuel having apparatus which automatically inserts the logs into the furnace combustion chamber. The log fuel is retained in a sloping ramp storage compartment. Electrical circuitry controlled by a thermostat operates to move a log into an elongated chamber from which a motor driven injector pushes the log into the combustion chamber through a doorway covered by a flexible, segmented flap covering and also a door which is pushed open by the advancing log. The presence of the log on a spring mounted grate operates certain switches to return the injection mechanism to its ready condition and also to operate a fan which provides combustion air to the combustion chamber. The reduced weight on the grate by the consumption of the log by the fire permits the grate to move to a position to re-initiate the log injection cycle.

Abstract: A heating device such as a fireplace has a fire box with an opening in one side and an arrangement for feeding long logs, at least two at a time parallel with one another, through the opening. The device includes an enclosure for the logs and may include a jacket around at least part of the fire box through which the enclosure extends.
