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 synthesis method for producing a refractory oxide-ceramic material of CaZrO.sub.3, in particular in the form of a refractory granular material that is preferably mechanically comminuted, in particular crushed and/or ground, as well as to a batch and a coarse ceramic, shaped or unshaped, refractory product containing at least one pre-synthesized refractory calcium zirconate-containing granular material.

The Smoke Chamber Sealing Device is a non-solely-cement method and system of sealing Smoke Chambers. Material such as metal, plastic, glass, composite, and/or any other material suitable for smoke chambers can be formed into the layers that seal smoke from going to where it is not supposed to go. One of many designs can involve installing metal walls on the inner walls of a smoke chamber, these metal walls would last much longer than cement and would be easier to work with considering the difficulties of parging a smoke chamber.

An excess enthalpy combustion device includes a furnace body and a feed mechanism disposed on one side of the furnace body. A flue gas outlet is provided on the furnace body. A wall of the furnace body includes a refractory material layer, an electric heating layer, and an insulating layer that are arranged in sequence from inside to outside. Two horizontal first refractory partitions which are staggered in the vertical direction are provided in an upper layer of the furnace body. Four vertical second refractory partitions which are staggered in the horizontal direction are provided in a lower layer of the furnace body; a third refractory partition parallel to a side wall is provided on the other side of the furnace body opposite to a grate mechanism. The combustion device adopts an electric heater to heat the furnace body when the electric heater is powered on.
