Elemental Analyzers for Quality Control of Coal

2017-12-12  For a proper proximate analysis, it is vital to know the moisture content of the coal as this value impacts all other parameters. Moisture can be divided into surface, decomposition, hydroscopic, and mineral moisture and can be determined with a thermogravimetric analyzer (TGA) or by the use of a furnace and an external balance.

Coal National Geographic Society

Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.
