- Coal is a hard, black colored rock-like substance. It is made up of carbon, hydrogen, oxygen, nitrogen and varying amounts of sulphur. There are three main types of coal – anthracite, bituminous and lignite. Anthracite coal is the hardest and has more carbon, which gives it a higher energy content.

- The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. All living plants store energy from the sun through a process known as photosynthesis. After the plants die, this energy is released as the plants decay.

- How Coal is Formed. Coal is a non-renewable energy source because it takes millions of years to form. That means what is in the ground now is all there is and we can’t realistically make more. The energy in coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago in swamp forests, even before the dinosaurs! When these giant plants and ferns died, they formed layers at the bottom of the swamps. Water and dirt began to pile up on top of the dead plant remains. Over thousands of years pressure and heat would build up on top of the plant remains, undergoing chemical and physical changes and pushing out the oxygen, turning these remains into what we call coal.

Coal Coal (from the Old English term col, which has meant mineral of fossilized carbon since the 13th century) is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.oal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction. Since 1983 the world top coal producer has been China.

What is coal? Simply put, coal-fired electricity generation is a five-step process: 1  Thermal coal (either black or brown) that has been pulverised to a fine powder is burned. 2  The resulting heat is used to turn water into steam.  The steam at very high pressure is then used to spin a turbine, connected to an electrical generator.

Properties of Coal The environments or conditions under which these coals were formed: anthracite coal, bituminous coal, Coals are classified into three main ranks, or types: lignite, bituminous coal, and anthracite. Lignite - is the lowest rank of coal - which means that it has the lowest heating value and lowest carbon content.

Greenhouse gas It makes sense, then, that coal combustion worldwide is the number-one contributor to the human-made increase of CO 2 in the atmosphere. Making matters worse, coal mining produces methane, a greenhouse gas with a global warming potential 25 times greater than that of CO 2 on a 100-year timeline.

- Methane (CH 4) is a gas formed as part of the process of coal formation – coalification. When coal is mined methane is released from the coal seam and the surrounding disturbed rock strata.Methane can also be released as a result of natural erosion or faulting.The methane content in coal seams generally increases the deeper the seam, and also with age.ethane is released during the process of extracting coal in both surface and underground mining. The released methane then mixes with air, which becomes highly explosive if methane concentration levels reach 5-15%. Methane explosions are devastating, causing significant loss of life and damage to property.

- The coal-to-coke transformation takes place as follows: The heat is transferred from the heated brick walls into the coal charge. From about 375°C to 475°C, the coal decomposes to form plastic layers near each wall. At about 475°C to 600°C, there is a marked evolution of tar, and aromatic hydrocarbon compounds, followed by resolidification of the plastic mass into semi-coke.

- The raw tar as obtained from the coke ovens is processed or distilled to produce a variety of products. Usually the first step in processing coal tar is to subject it to a primary distillation to produce several fractions of cuts.one Star coal tar coatings are products of carefully chosen coal tars having low carbon values, carefully blended with mineral fillers, carbon plasticizers and selected grades of heavy oils and solvents distilled from coal tar.

Coal The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.oal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about 7.25 billion tonnes in 2010 (7.99 billion short tons) and is expected to increase 48% to 9.05 billion tonnes (9.98 billion short tons) by 2030.

- The process of extraction of coal-bed methane targets methane in coal under the soil, created by the decay of organic matter over time. The decay of organic matter takes place incessantly in the garden, in the way of donations from animals and birds, leaves, roots, flowers, feathers and fallen old nests.

How was coal formed? Find out how coal is formed. Through animation, this video explains how, during the geologic period called the Permian, plant material accumulated in water and was buried by sediments where heat and pressure transformed it from the spongy substance known as peat to the hard carbon material known as coal.

How does coal form? please help? Coal form after plant materials are buried under sediment. Over the years materials become compacted. Coal is formed when peat is altered physically and chemically. This process is called coalification.. During coalification, peat undergoes several changes as a result of bacterial decay, compaction, heat and time.

The Origin of Coal Although coal forms less than one percent of the sedimentary rock record, it is of foremost importance to the Bible-believing geologist. Here is where he finds one of his strongest geological arguments for the reality of the great Noachian Flood. Two theories have been proposed to explain the formation of coal.

Coal and Air Pollution Carbon dioxide (CO 2) emissions from combusting fossil fuels are the main driver of global warming. CO 2 is also the main byproduct of coal combustion: nearly 4 grams of CO2 are produced for every gram of carbon burnt (depending on its type, coal can contain as much as 60 to 80 percent carbon). Methane (CH4) often occurs in the same areas that coal is formed, and is released during mining activities.

Everything You Need to Know About Coal Coal, the Organic Rock. Coal differs from every other kind of rock in that it is made of organic carbon: the actual remains, not just mineralized fossils, of dead plants.Today the vast majority of dead plant matter is consumed by fire and decay, returning its carbon to the atmosphere as the gas carbon dioxide—it is oxidized.irst the swampy peat is squeezed and heated to form a brown, soft coal called lignite. In the process, the material releases hydrocarbons, which migrate away and eventually become petroleum. With more heat and pressure lignite releases more hydrocarbons and becomes the higher-grade bituminous coal.
