ABSTRACT:
A fixed sulfur fuel is produced by proportioning sulfur-bearing coal and limestone in amounts which will cause the calcium in the limestone to react with a large amount of sulfur in the coal. The proportioned mixture is ground and blended and then balled or compacted to form pellets. By means of either a carbonizing or pyrolyzing technique conducted in a traveling grate machine, where the pellets are heated to at least 800.degree. F., the coal is pyrolyzed or carbonized, the limestone is calcined, and the sulfur is fixed in a calcium compound which remains stable in the ash after the pellets are burned as a fuel.
