Types of Coal

Coal is a multifaceted resource which differs in composition even inside the same deposit. There are four different types or ranking based on various levels of coal with differences in energy output as a result of increased temperature,pressure & time

Lignite is a brownish-black coal with great moisture and ash content and the lowest heating value of the four types of coal. It is used for generating electricity.

Subbituminous coal is a dull black coal consisting a higher heating value than lignite and used for electricity and space heating.

Bituminous coal is the most commonly used type of coal for electric power . Bituminous Coal is a dark, hard coal that has a higher heating value than lignite and subbituminous coal, but it has a lower heating value than anthracite.

Anthracite also known as "hard coal", hard and shiny and compact, thus consumed highest energy content of the all the four levels of coal discussed here. It is used for space heating and generating electricity.

  • How is Coal Formed ?

    Since the 13th century coal is derived from the Old English term col, which means "mineral of fossilized carbon".

    Coal consists of high content of carbon and other elements like, sulfur, hydrogen, oxygen, and nitrogen.

    Coal is a naturally black sedimentary rock occurring in rock strata in layers or veins called coal beds or coal seams.

    Anthracite coal is the solider form of coal, can be considered as metamorphic rock because of later exposure to high temperature and pressure.

  • What is Coal Tar ?

    Coal tar is a black fluid of tremendously high viscosity when coal is carbonized,

    Coal tar is among the by-products which manufactured coke or gasified to make coal gas.

    Coal tars are compound and variable mixtures of phenols, polycyclic aromatic hydrocarbons (PAHs), and heterocyclic compounds.

    Paracetamol is the only coal-tar derived analgesic which is still in use today, but industrial phenol is now usually synthesized from crude oil rather than coal tar.

  • What is Coal ?

    Coal is a combustible sedimentary rock composed generally of carbon and hydrocarbons.

    Coal is non-renewable resource which is the most abundant manufactured fossil fuel in the United States.

    Coal is the leading source of energy for the generation of electricity all over the world, also anthropogenic sources of carbon dioxide releases.

    Coal act as abundant resource that has been used for thousands of years to yield energy, mutually in the form of heat and electricity.

  • Effectiveness of Inorganic Coal

    Mineral coal is used in producing steam power to drive railway trains, Steam-ships and Steamers.

    Steam-power is produced from water boiled by mineral coal. Electricity is easily manufactured from coal by planting thermal stations near coal mines.

    Synthetic petrol is manufactured from mineral; coal through a kind of chemical process.

  • Coal

    Definition

    Coal is considered to be a fossil fuel which is dark black to brownish in color, rock formed from plants that have been fossilized through the process of oxidation. Coal contains amorphous carbon along with different organic as well some inorganic compounds and liberates carbon dioxide and other harmful gases when burned. Coal is widely used to generate electricity as well as heat.

  • Fly ash

    Definition

    Fly Ash are the fine particles or the residues which are generated during combustion of solid fuels such as coal. It is also known as "pulverised fuel ash". Along with the flue gases these fine particles  are driven out of the boiler. The components of fly ash vary and depends on the coal being burned.

  • Boiler

    Definition

    Boiler is a closed vessel in which water or other types of fluids is heated as a result vapour or steam is generated which helps to run turbines or engines and also heat produced is used for various other purposes. The sources of heat for the boiles is combustion of different fuels such as coal, natural gas, wood or other types of fuels.

  • Asphalt

    Definition

    Asphalt is brownish to black ,thick sticky and highly viscous liquid or semi solid compound. Asphalt is obtained during refining of coal or petroleum and consist of mixture of hydrocarbon. It is used in preparations of roads. Asphalt is composed of bitumen which is present in crude petroleum.

  • Combustion

    Definition

    Combustion is a process in which heat and light is produced, by the rapid chemical reaction between oxygen and other substances or fuels such as wood, oil, coal, petroleum etc., 

  • Global warming

    Definition

    Global warming can be defined as an increase in the average temperature of the earth's atmosphere that causes changes in the climate which may result from the greenhouse effect. Burning of coal is one fo the cause that generates carbon dioxide and other gases which may  increase temperature. Several other factors are also responsible for global warming.

  • Steam locomotive

    Definition

    Steam locomotive is moved by using the power of steam which is generated in its own boiler by the combustion of fuels such as coal, oil or petroleum. Steam locomotives are also used to move trains along railway tracks for railway transport.

  • Steam engine

    Definition

    Steam engine is a heat engine in which a hot steam is used that converts the heat energy into mechanical energy. Sliding piston is present in the cylinder which moves by the expansion action of the steam which is generated in a boiler. Coal, wood or other combustible material are used as a source to produce steam in a boiler.

  • How Recycling Saves Energy?

    When we manufacture new products from virgin materials, more energy is consumed. Other natural resources such as fossil fuels (Oil , Petroleum, Natural gas, Coal) are also used during manufacturing of products. But when we make products out of recycled materials we can reduce the use of energy sources. The steps in the process of manufacturing of recycled product is reduced which helps to save energy.
