Abstract: A combustion apparatus is provided, preferably of the thermal heat regeneration type, in which noxious or other gases are passed to an incineration chamber, to be burned at a sufficiently high temperature that they are disposed of. The apparatus is constructed as a compact unit, as essentially a single oven separated into a plurality of heat exchange sections, and with plenums therebeneath, fed by an inlet duct, and able to deliver the products of combustion to an outlet duct, both preferably disposed beneath the plenums, and preferably mounted on a common supporting frame for facilitating sufficient mounting of the apparatus, as well as ready transport of the same.

Abstract: An incineration apparatus is provided, preferably of the thermal heat regeneration type, in which noxious or other gases are passed to an incineration chamber, to be burnt at a sufficiently high temperature that they are disposed of, and in doing so, pass through heat-exchange beds of elements such as stones or the like, whereby the direction of gas flow may optionally be reversed. The stoneware beds reside in recovery chambers adjacent but contiguous with the combustion chamber, separated therefrom by built-up refractory blockwalls. The walls are of arcuate configuration and support the heat-retention elements in the recovery chambers. The walls are generally the thickness of a single refractory block, and are of a radius that is less than any radius of the combustion chamber and are of a sufficient radius such that the forces of the stone or other heat-retention elements outside the walls may be resisted to prevent wall collapse.
