  • Firebox floor of a furnace for combusting wood
    Patent number: 11703222
    Abstract: 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.
