بیشترUsually coal has a carbon content of more than 70% by weight. The calorific value of coal is in the range of 25–35 MJ/kg. There are three main types of coal: lignite, bituminous coal and anthracite. Anthracite is the highest quality coal, as it has a carbon content of more than 90% and the highest calorific value.
بیشترThe given values are for fuels with the given density. The variation in quality may give heating values within a range 5 -10% higher and lower than the given value. Also the solid fuels will have a similar quality variation for the different classes of fuel. 1 Btu (IT)/lb = 2.3278 MJ/t = 2327.8 J/kg = 0.55598 kcal/kg = 0.000646 kWh/kg.
بیشترThe 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.
