There are four main coal types lignite, subbituminous, bituminous and anthracite. Heres a look at their characteristics and uses. Found in the earths crust, coal is a fossil fuel that is
ADVERTISEMENTS Coal Types and Uses of Coal Coal is a black or brown rock, consisting mainly of carbon, which is formed by the compressed vegetative remains of past ages. ADVERTISEMENTS Much of the presentday high quality coals were deposited during carboniferous era, i.e., about 300 million years ago. More recent deposits of Tertiary age are
What are the different types of coal and their uses Coal is classified according to moisture, natural gases and carbon content. With an increase in the amount of carbon, its calorific value rises. The less moisture and volatile substances it contains gases, the easier it can be stored and transported. 1. Lignite
Bituminous Bituminous coal is a middle rank coal between subbituminous and anthracite. Bituminous usually has a high heating Btu value and is the most common type of coal used in electricity generation in the United States. Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers.
Coal has a major use as an energy source for electricity burning of coal creates heat, the heat boils water, and steam from the water moves large turbines to create energy. But, how the different types of coal are used depends on the country and region they are used in. The type of coal found in a particular region and how abundant and cheap
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
What are the Different Types of Fuels and Their Characteristics Fuels Most of the substances used for burning are fuels. Substances that produce heat and light energy on burning are called fuels. Some commonly used fuels are wood, coal, cow dung cakes, kerosene, LPG, petrol, and diesel. We use fuels for cooking, heating, in automobiles,
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.
Hard vs. Soft Coal falls into two main categories hard and soft. Soft coal is also known as brown coal or produces more hard coal than any other country by a factor of about three. The whopping 3,162 million metric tons of hard coal produced by China dwarfs the output of the second and thirdranked producersthe U.S. at 932 million metric tons and India at 538 million metric
Peat Coal Peat coal contains high moisture and a small percentage of volatile matter and of Carbon. It is Wet used in power plant. It has very less heating value of 2393 KJKg. Lignite Coal Lignite coal has fixed carbon moisture content 30 to 45. Proper storage is required to spontaneous combustion. Used in power plants locally.
Coal is defined as having more than 50 percent by weight or 70 percent by volume carbonaceous matter produced by the compaction and hardening of altered plant remainsnamely, peat deposits. Different varieties of coal arise because of differences in the kinds of plant material coal type, degree of coalification coal rank, and range of
Coal has many important uses worldwide. The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Different types of coal have different uses. Other important users of coal include alumina refineries, paper manufacturers, and the chemical and pharmaceutical industries.

Bituminous coal is harder and blacker than lignite and subbituminous coal, and can be divided into two types thermal and metallurgical. The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel.
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. Types, or ranks, of coal are determined by carbon content.
