Coal is derived from the remains of land plants that accumulated at first as peat Upon burial, peat is converted to coal by millions of years of exposure to elevated temperatures and pressures during which diagenesis converts plant debris into a highly aromatic, threedimensional structure (Teichmuller, 1987).
Metallurgical coal is more scarce and valuable than thermal coal, so in practice metallurgical coal is rarely used to generate electricity. Metallurgical coal is also commonly referred to as coking coal. Coking coal has physical properties that when heated cause it to soften, liquefy and then resolidify into a harder substance known as coke.
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities.. Coal gas contains a variety of calorific gases including hydrogen, carbon monoxide, methane ...
The coke oven byproduct plant is an integral part of the byproduct cokemaking process. In the process of converting coal into coke using the byproduct coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as hot, raw coke .

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed is considered the lowest rank of coal due to its relatively low heat has a carbon content around 60–70 percent. It is mined all around the world, is used almost exclusively as a fuel for steamelectric power generation, and is the coal which is most ...
Aug 11, 2015· In this work, the influences of coal moisture control (CMC) and coal briquette technology on structure and reactivity of cokes were investigated by adding a certain proportion of briquette into raw coal with different moisture. The coking experiments were carried out in a tested cokeoven of 70 kg, and the properties of asobtained coke were analyzed by Xray diffraction (XRD), .
