Abstract
A method and apparatus for extracting heat from a combustible material are disclosed which include the formation of a solid material strip of the combustible material, the formation of a series of spaced holes in the material strip, and the combustion of the material strip. The method and apparatus are particularly useful when a mixture of coal, clay, and lime is used as the combustible material, and the products of the combustion then include a structurally intact, solid residual strip composed substantially only of dehydrated clay and calcium sulfate, and a fluegas substantially free of carbon monoxide, nitrogen oxides, sulfur oxides, and micro fly-ash. Because of the stable and uniform combustion characteristic, it is also suitable for the co-combustion and reduction of most toxic and solid wastes into safe, recyclable residues.
