Most coals have internal layering, called banding. Coal types, and subsets of types, called lithotypes, are based on the presence or absence of banding, and the brightness or dullness of individual bands. Coal lithotypes are further divided into microscopic.Properties of Coal • Coal properties are evaluated by different methods. • The most commonly used methods are Proximate and Ultimate analysis of the coal. • Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. • Ultimate Analysis gives the elemental composition of the coal. • Other methods like Macarel analysis is also used.
Different coal types are all minerals and rocks made largely of carbon.This fossil fuel generates ~40 of the world's electricity and about 25 of the world's primary energy.However, not all coal used is the same it comes in different quantity levels of carbon—which dictates the quality of the coal.
