coal classification | Types & Facts | Britannica.com

Coal classification: Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users and to researchers.

Different Types of Coal - Difference Between

It is mainly classified into different ranks or grades, based on the percentage of carbon in it. Coal is an organic rock primarily containing carbon. In addition to carbon, it also consists of other elements like hydrogen, sulphur, oxygen, nitrogen and some inorganic materials, minerals and water. Coal is one of the most important fuel resources.

How much carbon dioxide is produced when different fuels are burned? Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce when burned. To analyze emissions across fuels, compare the amount of CO2 emitted per unit of energy output or heat content.

Coal | Types of Coal: Peat, Lignite, Bituminous Coal ...

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.
