K Investments imports and distributes anthracite coal from Ukraine. We also import anthracite coal from Russia and Peru. Our offer includes all fractions of anthracite coal. Fuel is shipped by the sea (Peru) or rail.
What is anthracite?
Anthracite coal is a type of fossil fuel with high percentage of pure carbon (up to 97 per cent, usually 93-95). Characterized by higher temperature of burning and calorific value in comparison to other solid fuels available on the market. Lumps of anthracite coal have greyish-black or black shade and semi-metallic shine. Pieces of anthracite coal are harder and more solid when compared to other solid fuels.
Anthracite coal contains:
- carbon (usually up to 94 %)
- sulphur (0,6-1,5% - depending on type and source)
- volatile matter (2,5-5%- depending on type and source)
- water (moisture 1-3%)
Depending on type and source, composition may vary in content of quartz, hydrocarbons and pyrite.)
Anthracite coal available on the market is being offered in various granulation size depending on the aim of use. The finer the coal, the more ash it will produce and the less energy will be emitted.
How was the anthracite coal created?
Anthracite coal is a highly processed metamorphic rock created in the environment of high temperature and pressure.
Where does it occur?
Anthracite coal occurs in the majority of hard coal district areas created in carboniferous era. Some resources of anthracite appeared to be from Permian period. This feedstock occurs in:
- Great Britain,
- North Korea,
- South Korea,
- Russia (Siberia),
Minor resources of anthracite coal were found also in Poland in the area of Wałbrzych and Nowa Ruda. Wałbrzych mined it for 5 years. After closing the mine, anthracite coal was no longer listed as a natural source of energy occurring in Poland.
Use of anthracite coal
Anthracite coal characterizes with slow and mild burning with trace smoke and dustiness. These features made it the most demanded source of energy for heating buildings. Thanks to its purity and high calorific content, anthracite coal is used in:
- power industry (electrode production),
- as a fuel of special use.
