What Is the Bulk Density of Coal? Reference

Aug 04, 2015 The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter. It is a mature coal and is very hard and shiny. Bituminous coal has a bulk density of 42 to 57 pounds per cubic feet, or 673 to 913 kilograms per cubic meter.

Coke (fuel) Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low
