A furnace for combusting wood comprises a firebox floor in a primary burn chamber of the furnace, where the wood is received for generating a gas therefrom, that is defined by a thermally conductive body of refractory material. The body of refractory material defines an upper support surface arranged to support the wood above or over the same. The body of refractory material also defines, beneath the upper support surface, a duct as part of a secondary burn chamber of the furnace which is arranged (i) to be communicated with the primary burn chamber of the furnace to receive the gas generated by heating of the wood therein and carrying combustible products, and (ii) to convey the gas in a manner supporting combustion of the combustible products carried thereby.

A cooking appliance has a combustion zone air flow path which includes a combustion zone. A first cooking zone is positioned in thermal communication with the combustion zone. During operation of the cooking appliance, combustion products produced in the combustion zone indirectly heat air whereby heated air is produced that is then introduced into the combustion zone and/or the first cooking zone.

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.
