Bituminous Coal Classifiion Indonesia

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.

Lignite - Wikipedia

Lignite is brownish-black in color and has a carbon content around 60–70 percent, a high inherent moisture content sometimes as high as 75 percent, and an ash content ranging from 6–19 percent compared with 6–12 percent for bituminous coal.

Sub-Bituminous Coal Characteristics - The Balance

Mar 15, 2019· The coal's sulfur content is generally less than 2 percent by weight. Nitrogen makes up approximately 0.5 to 2 percent of the coal's weight. Sub-bituminous coal typically is found near the surface, which results in lower mining costs, making it a relatively inexpensive coal.

What are the different types of coal? | American ...

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or “ranks,” of coal are determined by carbon content.
