A portable temperature regulated rotisserie and barbequing apparatus including a substantially cylindrically-shaped housing comprised of a stainless steel and further including a set of carrying handles. The hollow cylindrically shaped housing includes a latching mechanism to releasably secure the planar drip pan at the second end and a centrifugal fan including a plurality of concave blades which increase the volume and air speed to the blades. The spit releasably attached the centrifugal fan and rests on the shaft anchor.

A pellet stove to heat the interior of a structure and provide a heating surface for cooking. The pellet stove has a hopper storing pellet fuel, a core assembly inside a stove enclosure, a primary burn chamber assembly for burning pellet fuel and an air venting system. The hopper gravity feeds pellet fuel to the primary burn chamber assembly. The core assembly has a burn chamber housing connected to a flame chamber by a burn channel. The primary burn chamber assembly has a burn basket and a fuel control mechanism to control the amount of pellet fuel burned in the burn basket. The venting systems draws inlet air into and discharges exhaust air out of the pellet stove, which is sealed to prevent drawing inlet air from or discharging exhaust air to the structure interior. Fire in the flame chamber can be seen through an exterior glass panel.

A cooking appliance is disclosed including a burner assembly that effectively and efficiently combusts fuel and directs the resulting smoke from a burn pot of the burner assembly to a cook chamber of a cooking appliance. The burner assembly may include a series of openings and curved faces that provide airflow to push smoke from the burn pot to the cook chamber and provide more turbulence and better heat and smoke circulation in the smoker. The burn pot may define one or more vents and include a one or more curved or shrouded surfaces. The burner assembly may include one or more deflector plates configured to direct the flow of smoke from the burn pot to the cook chamber.

A control system for a fuel-burning appliance such as a wood or pellet burning stove is disclosed. The control system may include a particulate matter sensor. The control system may also include an ignition system to ignite an ignition charge of ignitable fuel. A processor controls the operation of the functional components of the appliance to maintain operating conditions within pre-determined parameters.

A furnace including a combustion chamber for burning fuel can have increased fuel burning efficiency, increased heating efficiency, and decreased harmful emissions of combustion byproducts. A combustion air delivery system delivers primary and secondary combustion air to the combustion chamber. Primary and secondary combustion air may be delivered at amounts that increase burning efficiency. An amount of secondary combustion air can be controlled by a valve system. A heat transfer device efficiently transfers heat from products of combustion for heating an enclosed space.
