ABSTRACT:
A method of and an apparatus for heating, melting and production of gaseous fuel include supplying air, coal, steam into a melt. The melt contains elements readily oxidized by air. These elements produce oxides readily reduced by carbon. The overall results of the reactions of elements oxidation and reduction consist in the production of CO containing gas and evolving heat. The heat evolved is extracted from the melt by submergence of solid to be heated into the melt, by injection of heated gases into molten slag, by heat exchange between the wall confining the melt and gas, liquid or solid to be heated, or by conversion of steam into H.sub.2 and CO.
