ABSTRACT:
In the combustion of high sulfur coal, SO.sub.x emission is reduced by pyrolizing the coal in a reducing atmosphere to form char and convert the sulfur compounds to combustible gases including H.sub.2 S. The H.sub.2 S is reacted with the coal and the char to produce ash containing sulfur which is easily removed from the combustion process. A three zone furnace includes a zone in which the coal is pyrolized in a reducing atmosphere to convert the sulfur compounds to combustible gas which reacts with the coal and char.
