Abstract
Sulfur-containing coal is combusted in a cyclone furnace under strongly reducing conditions with a sulfur fixing agent such as lime to produce a basic slag containing the ash and sulfur content of the coal and a product gas of high combustible content which may be burned as a fuel gas in a steam generator or otherwise to yield an exhaust gas which does not require scrubbing.
