Coal assay Wikipedia

Chemical properties of coal. Coal comes in four main types or ranks: lignite or brown coal, bituminous coal or black coal, anthracite and graphite.Each type of coal has a certain set of physical parameters which are mostly controlled by moisture, volatile content (in terms of aliphatic or aromatic hydrocarbons) and carbon content.. Moisture. Moisture is an important property of coal, as all

Coke (fuel) Wikipedia

The industrial production of coke from coal is called coking.The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). This process vaporises or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar.

Mill Inerting Systems Presentation to the ASBCUG

Jun 07, 2018· Higher moisture content requires temperature extremes inside the mill. High moisture, high volatile matter and highly reactive coals are prone to self heating and can spontaneously ignite due to rewetting. Rehydration is exothermic and dried coal that is stagnate anywhere in the coal mill can begin to smolder and burn.

Anthracite is very high rank coal in which there is virtually no volatile matter and consequently has a high percentage of carbon. Very high rank anthracites (meta-anthracite) which have volatile matter of <3% are used extensively in the reduction of silica to silicon metal and in the production of ferro-silicon.
