The materials specifically covered by these standards can be in the form of lump coke, pulverized coal, bituminous coal, coke and coal ash, reformed gas, and polishing and etching coal. These standards also include the thermophysical property tables for methane, ethane, propane, normal butane, and isobutane.
Anthracite Coal is very shiny, hard black coal, high carbon content and energy density, repels moisture, for domestic industrial uses, including smokeless fuel; Bituminous Coal is softer and shiny, moisture content is 8 -20%, possible for coking coals, volatile matter from 16% - 40%, can be used for thermal or metallurgical applications; Sub-bituminous Coal is soft and black with energy ...
The verdict: Experts say Australian export coal is of a higher quality on average compared with other countries, meaning less is needed to generate the same amount of energy. This leads to lower ...
4 A Critical Review of Published Coal Quality Data From the Southwestern Part of the Powder River Basin, Wyoming Assessing the coal quality variations is usually straight-forward for regions like the Gillette coal field, where mining has been extensive and coal analytical data are abundant.
[PDF]Geology and coal quality of the South African coalfields Coal is found in South Africa in 19 coalfields (Figure 1), located mainly in KwaZulu-Natal, Mpumalanga, Limpopo, and the Free State, with lesser amounts in Gauteng, the North West Province and the Eastern Cape. Table I summarizes pertinent geological information about the coal seams in ...

Coal rank is an indication of how much transformation the orig inal plant material has under gone. The American Society for Testing and
This value can vary from 10500 kJ/kg to 25000 kJ/kg depending on the quality and type of the coal. You should have an idea of the type of coal, or the source or mine from where the the plant gets the coal. Published data about the sources, mines, regions or the procurement data gives an idea about the HHV of coal. For this example we use a HHV ...

Quality Coal. Carlisle Mine Coal—Some of the Finest in the Illinois Basin. Carlisle's coal features: High BTUs (11,400 btu) Low chlorine (<.10%) Sunrise Coal travels better than most other Indiana coals, and the low chlorine levels eliminate the corrosion concerns often associated with coal from the Illinois Basin.
coal is heated to 950°C (1,742°F) in the absence of air under specified conditions - components of coal, except for moisture, which is liberated usually as a mixture of short & long chain hydrocarbons, aromatic hydrocarbons & some sulphur - measured practically by determining the loss of weight Consists of a mixture of gases, low-boiling-point
Coal, one of the most important primary fossil fuels, a solid carbon-rich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in .

Coal is plentiful in the United States and inexpensive for its energy content. But its use comes at a cost to the environment. Learn the pros and cons of this energy source from the National Academies, advisers to the nation on science, engineering, and medicine.
[PDF]Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.

Regarding global coal reserves, Indonesia currently ranks 9th, containing roughly 2.2 percent of total proven global coal reserves according to the most recent BP Statistical Review of World Energy. Around 60 percent of Indonesia's total coal reserves consists of the cheaper lower quality (sub-bituminous) coal that contains less than 6100 cal/gram.
