Abstract
The physical transformation of the mineral matter in coal has been studied in a laboratory furnace using size-graded, pulverized samples of a lignite and a bituminous coal. The mineral matter is originally distributed in micron-size inclusions in the coal particles. The paper illustrates how the final particle size distribution of the ash produced at combustion temperatures of 1250 to 1830K is determined by a combination of agglomeration of fused mineral matter, cenosphere formation due to gas evolution and vaporization and recondensation of volatile constituentsKeywords
