ABSTRACT:
A method of reducing sulfurous pollutants from furnaces fired with sulfur-containing coals is disclosed. The method comprises the steps of recovering fibrous material from green crops, comprising leaves, grasses, legumes, stems of green plants and tree leaves by subjecting the green crops to a mechanical pulping action and separating juices generated by the pulping action from the fibrous material. The fibrous materials are burned with the sulfur-containing coal in the furnace thereby permitting alkaline residues from the fibrous material to react with sulfur oxides generated by the combustion of the coal, the reaction converting the oxides to sulfur salts and permitting the salts to be recovered in ash from the furnace thereby reducing the pollutants from the furnace by the reaction and by dilution of the combustion gases.
