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. There are four types of coal, ordered from highest to lowest rank below. It has a brittle texture and lustrous sheen. It is used mostly in industrial settings and the metals industry due to its high heat value. Sub-bituminous coal or black lignite is a grey-black or dark brown coal. It ranges from hard to soft as it represents an intermediate stage between low quality lignite and higher quality bituminous coal.

Anthracite is a dark black form of coal and the highest quality coal. In addition, anthracite is usually the oldest type of coal, having formed from biomass that was buried million years ago. Its clean burning properties allows anthracite to burn longer than wood, making it appealing to use in home heating stoves. Fossil Fuels. Nuclear Fuels. Acid Rain. Climate Change. Climate Feedback. Ocean Acidification.

Lower grade coal. Intermediate stage. Dark to black brown. Moisture content is high over 35 per cent. Creates fire accidents in mines] Bituminous Coal Soft coal; most widely available and used coal. Derives its name after a liquid called bitumen.

Moisture and volatile content 15 to 40 per cent Dense, compact, and is usually of black colour. Does not have traces of original vegetable material. Calorific value is very high due to high proportion of carbon and low moisture. Used in production of coke and gas. Anthracite Coal Best quality ; hard coal.

Very little volatile matter. Negligibly small proportion of moisture. Semi-metallic lustre. Ignites slowly and burns with a nice short blue flame. Sharing is Caring!!
