Types of Coal. On the basis of carbon content, it can be classified into the following three types: Anthracite. This is the best quality of coal and contains 80 to 95 percent carbon.It has very little volatile matter and a negligibly small proportion of moisture.; It is very hard, compact, jet black coal having semi-metallic lustre.; It has the highest heating value and …


Sometimes, coal-fired electric power plants are built near coal mines to lower transportation costs. Coal is classified into four main types, or ranks (lignite, subbituminous, bituminous, anthracite), depending on the amounts and types of carbon it contains and on the amount of heat energy it can produce.


Process Of Low Rank Coal Of East Kalimantan Yuli Patmawati Abstract:- Indonesia is one of the countries that has large coal reserves in the world; 67,198,300,021 tons/year of low-rank coal such as lignite production in East Kalimantan. Coal is divided into four classes: lignite, sub-bituminous, bituminous, and anthracite.


According to the percentage of carbon, volatile, moister content and its calorific value (a measure of heating power) coals classified into different types. The quality changes due to age and depth at which it is buried. The coal is mainly divided into five types, peat, lignite, bituminous, anthracite and graphite. Peat


There are four types of coal - peat, lignite, bituminous and anthracite. Each type has different proportions of carbon and thus, have different uses. Peat - This type of coal has less than 40% to 50% of carbon, while the remaining is moisture. This makes it …

These four types can also be divided between low-rank coals (lignite and sub-bituminous) and hard coals (bituminous and anthracite) based on the presence of carbon content. Generally, high carbon content is found in coals that have spent more time during their formation, while the lower carbon content is found in younger coals that spent less ...


Coal itself is divided into four main types: anthracite, bituminous, sub-bituminous and lignite. Lignite is Victoria's brown coal, used domestically only. Most Australian export coal - steaming and coking - is bituminous. Indonesian steaming coal, by contrast, is sub-bituminous, with lower heating value than bituminous products.

This process causes the peat to progress through brown coal, lignite, sub-bituminous coal and then to bituminous coal (the category most of Australia's coal currently mined belongs to) and finally anthracite. Through this process, the carbon content of the coal increases as does the energy content of the coal.


There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are:Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...


It can be divided into two categories: thermal and metallurgical. Thermal coal, also known as steaming coal, is used to generate power for public electricity grids. Metallurgical coal, on the other hand, is used to create coke, a carbon-concentrated rock, for iron and steel-making. 4. Lignite.


Coal is divided into four classes: anthracite, bituminous, sub-bituminous, and lignite.

The products of coalification are divided into four major categories based on the carbon content of the material. It is the carbon content of the coal that supplies most of its heating value. The greater the carbon to oxygen ratio the harder the coal, the more reduced the state of the carbons and the more potential energy it contains.


Coal is divided into four classes: anthracite, bituminous, sub-bituminous, and lignite. Elemental analysis gives empirical formulas such as C 137 H 97 O 9 NS for bituminous coal and C 240 H 90 O 4 NS for high-grade anthracite.


Due to a rise in demand for coal, many mining techniques have evolved to extract the fossil fuel. A large-scale mining of coal requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. Depending on their properties, coal is mainly divided into four types such as peat, lignite, bituminous and anthracite.

as is evident from a comparison of the moisture contents of different ranks of coal from lignite to anthracite. The moisture in coal may be divided into four types: inherent moisture, surface moisture, decomposition moisture, and water of hydration of mineral matter. Inherent moisture is equally termed bed moisture or equilibrium moisture.
