Process for reducing sulfur contaminant emissions from burning coal or lignite that contains sulfur
Patent
·
OSTI ID:6573485
A process for preparing a coal or lignite fuel that contains sulfur for combustion wherein reduced amounts of sulfur containing air contaminants are emitted from the combustion is disclosed. In the disclosed process, the coal or lignite that contains sulfur is first pulverized and is then mixed with a finely divided inorganic material. The inorganic material can be at least one of the oxides, hydroxides or carbonates of sodium, potassium, calcium or barium or it can be dolomite. By forming the mixture of coal or lignite and the inorganic material into briquettes or pellets, the mixture can be conveniently shipped, stored and used in conventional combustion equipment.
