Hard coal

Hard coal is composed of several basic elements: carbon, hydrogen, oxygen, nitrogen, phosphorus and sulphur. It is a sedimentary rock of plant origin, created mostly in the Carboniferous period from plant material that has been coalified in anaerobic conditions. According to the carbonification level of fuels that depends on their percentage content of pure carbon, the fuels can be divided into several types: peat (ca. 39 C%), brown coal (ca. 46 C%), flame coal (ca. 55 C%), gas coal (ca. 54 C%), orthocoking coal (ca. 59 C%), semicoking coal (ca. 60 C%), anthracite (69 C%).

Today, hard coal is one of top fossil fuels. Its quality depends on many parameters, among others on its calorific value, ash content, and sulphur content. The coal that we import comes from trusted mines which ensure stable required parameters including high calorific value, low ash and sulphur content, which makes it more environmentally-friendly and safer for furnaces.

We offer several coal products:

The coal offered by the company is sorted at the company’s own Transshipment Terminal under strict quality control.

grain coal fraction 80-200 mm, the coal with the highest calorific value, it is characterized by a low ash content, and long heat content;

80-200 mm
Nut coal

grain coal fraction 40-80 mm, the so-called coarse coal, flame coal, burning with long-lasting and bright flame, it is characterized by a low ash content, and a low sulphur content, which protects furnaces;

40-80 mm
Pea coal

grain coal fraction 20-40 mm, medium type coal with a high calorific value, and a low ash and sulphur content;

20-40 mm
Eco pea coal

grain coal fraction 8-25 mm, medium type coal, flame coal, which in its combustion process burns with long-lasting bright flame. Thanks to its low sulphur content, it is more friendly to the environment and prevents furnace fouling. Bialchem sells eco pea coal in bulk and in 25 kg bags;

8-25 mm
Fine coal

grain coal fraction 1-20 mm, a fine coal characterized by a high heat content and fit for boilers with diverse heating power, both for furnaces with automatic feeders, and traditional furnaces;

1-20 mm
