Bituminous coal grain size
The specific gravity of fly ash ranges from a low value of 1.90 for a sub-bituminous ash to a high value of 2.96 for an iron-rich bituminous ash. 3. Size and Shape of Fly Ash As the flyash is a very fine material, the particle size ranges in between 10 to 100 micron. The shape of the fly ash is usually spherical glassy shaped. 4. ColourThe mesh size of sieves used in sieve analysis is selected in accordance with the State Standard [ 1 ]. The main range includes sieves with a mesh size of 100, 50, 25, 13, 6, 3, 1 and 0.5 mm.

Bituminous coals generally have calorific values above 11,500 Btu/lb and volatile matter below 14% (ASTM, Jackson, 1997). In the Illinois Basin (and western Kentucky), however, the lower rank end of what are termed bituminous coals in the United States have calorific values of 11,100 to 11,300 Btu/lb.E8R07932 – Bituminous coal – 1 Kg of Bituminous coal fragments (example of a Sedimentary rock)The properties of the coal fly ash depend on the physical and chemical properties of the parent coal, coal particle size, the burning process and the type of ash collector. ... High-volatile bituminous coal due to its high volatile matter content generates high pressure during carbonization which is detrimental to the coke oven walls ([68, 69].
