The No. 16 coal seam is the main coal seam of the Yimin Coal Mine and has a thickness ranging from 1.90 to 41.75 m with an average of 15.35 m.

US4192652A Process for preparing sulfurcontaining coal

US4192652A Process for preparing sulfurcontaining coal

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. In the disclosed process, the coal or lignite that contains sulfur is pulverized, deeply cleaned, mixed with a finely divided inorganic material, and then formed into briquettes or pellets.
