8.3.2 Fly ash, bottom ash, and other coal ash masonry blocks. ... Bituminous coal is derived from dense sedimentary rock. It is used for the generation of steam–electrical power. Anthracite coal is the highest-ranked coal. It is a hard, glossy coal used primarily for residential and commercial space heating.

Physical, chemical, and geotechnical properties of coal ...

Fly ash can be classified according to the type of coal from which the ash was derived. There are basically four types/ranks of coal: anthracite, bituminous, sub-bituminous, and lignite. The principal components of bituminous coal fly ash are silica, alumina, iron oxide, and calcium, with varying amounts of carbon.

USGS Fact Sheet 076-01: Coal Combustion Products

Coal combustion products (CCP's) are the inorganic residues that remain after pulverized coal is burned. Coarse particles (bottom ash and boiler slag) settle to the bottom of the combustion chamber), and the fine portion (fly ash, fig. 1) is removed from the flue gas by electrostatic precipitators or other gas-scrubbing systems.

Beneficial Use of Coal Ash in Anthracite and Bituminous ...

Pulverized Coal Fly Ash. The bulk chemical composition of fly ashes can generally be correlated with the rank of the coal that was the source of the ash. Western lignitic and sub-bituminous coals are in general more calcium rich when contrasted to eastern bituminous and anthracites which tend to be more silica and alumina rich.

PRB Coal Properties - boilercleaning.org

PRB Coal Properties. The Powder River Coal (PRB) is classified as sub-bituminous ranked coal. Unlike higher ranked bituminous and anthracite coals, which have tight pore structures that limit the amount of inherent moisture they could hold, low rank coals like PRB coal have this looser pore structure and additional moisture retention capacity.
