Classification of Coal

Anthracite coal is the last classification, the ultimate maturation. Anthracite coal is very hard and shiny. 1) Volatile matter - dry mineral matter free basis. In coal, those products, exclusive of moisture, given off as gas and vapor determined analytically. Anthracite coal creates a steady and clean flame and is preferred for domestic heating.

 · Macerals are the altered remains and byproducts of the original plant material from which the coal-forming peat originated. Macerals are to coal as sediment grains and cements are to sedimentary rocks. Coal petrographers (people who study coal under a microscope) separate macerals into three groups, each of which includes several maceral types.

Coal Formation | Miners Museum – Glace Bay Nova Scotia …

Peat – Stage One. Peat is the first stage in the formation of coal. Normally, vegetable matter is oxidized to water and carbon dioxide. However, if plant material accumulates underwater, oxygen is not present and so only partial decomposition occurs. This incomplete destruction leads to the accumulation of an organic substance called peat.
