Claims.—(1.) The process for burning fuel for the purposes set forth, which consist in top-loading the fuel into a closed-bottom shaft-furnace, blowing into the mass of said fuel a blast of air with superheated steam to effect complete combustion of the fuel in said furnace, leading the incandescent gases from the top of the fuel-bed direct to the furnace or oven to be heated thereby, and removing the excess of ashes from the bed of the furnace. (2.) Producing completely oxidized incandescent gases for the purposes set forth, by blowing a sufficient blast of air with superheated steam into and up through a deep bed of fuel contained in a chamber having a closed bottom and a top gas-emission flue. (3.) A furnace for the purposes set forth, consisting of a vertical chamber having top fuel-loading and bottom ash-removing vents and top gas-emission flue, which chamber is adapted to carry a deep bed of fuel, and is fitted with tuyeres for delivering a blast of air and superheated steam into the body of live fuel therein in sufficient volume to blow the mass of fuel into complete incandescence. (4.) A stack furnace for the purposes set forth, wherein all the air required for complete oxidation of the fuel is supplied through tuyeres blown by jets of superheated steam which direct it into the bed of live fuel in said furnace, and wherein also incandescent gases are conveyed from above the fuel-bed into a neck or flue which leads them to the furnace, kiln, or oven in which they are utilised.
