    COAL A Fossil Fuel

    Coal reserves are beds of coal still in the ground waiting to be mined. The United States has the worlds largest known coal reserves, about 263.8 billion short tons. This is enough coal to last approximately 225 years at todays level of use. Coal production is the amount of coal

  • From Peat to Anthracite Different Types of Coal

    From Peat to Anthracite Different Types of Coal

    Lignite, commonly referred to as brown coal, is the very first coal formation, or the youngest of the coal products. With high emissions and low energy value, this type of coal is most used in power plants. Because lignite is the youngest of the coal family, it has the highest moisture content. This high moisture content makes the lignite ...

    Types of coal. Coal is classified into four main types, or ranks anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants ...

    Apr 27, 2016 Coal is a fossil fuel that is, essentially, the altered remains of prehistoric vegetation, as the World Coal Association WCA puts it. However, there are a number of different coal types. Coal originally began to form during the Carboniferous period, which took place between 360 and 290 million years ago. Put simply, plant matter accumulated in swamps and peat bogs, and
