COAL
We supply hard coal grades D, DPK, DOMSSH, LOW VOL PCI, Petcoke and Anthracite. It is widely used as fuel for household needs, completely necessary for foundries operation and is used by thermal power plants for electricity generation.
*Petroleum Coke (PETCOKE)
Also known as petcoke, is a type of coal obtained through the carbonisation of the fractions with high boiling points produced during the distillation of oil. This material is often used in place of traditional coke or in the production of electrodes for batteries:
| Ash, dry basis, max, % | 1 |
|---|---|
| Moisture as received, typical, max % | 7 |
| Sulphur, dry basis, max, % | 5 |
| Volatiles, daf, max, % | 13 |
| Hardgrove Grindability Index (hgi) | 55-96 |
| Net calorific value as received, min, kcal/kg | 7600 |
*ANTHRACITE
Considered the rarest and the most highly prized and mature type of coal. It makes up just 1% of total global coal reserves, and has a higher carbon content than the other three types of this material. This means that, in addition to domestic applications, anthracite is also suitable for specific industrial uses, as it can generate more heat and produces less waste:
| Ash, dry basis, max, % | 12.0 |
|---|---|
| Moisture as received, typical, max % | 17.5 |
| Sulphur, dry basis, max, % | 1.2 |
| Volatiles, daf, max, % | 4 |
| Fix carbon % | 80-95 |
| Size, mm | 0-6, 6-13, 13-30, 30-80 |
*DOMSSH
Suitable for boilers, boiler installations and all types of furnaces, so it can be used for heating any buildings and building complexes that have their own boiler houses:
| Ash, dry basis, max, % | 12.0 |
|---|---|
| Moisture as received, typical, max % | 17.5 |
| Sulphur, dry basis, max, % | 0.6 |
| Volatiles, daf, max, % | 44.0 |
| Net calorific value as received, min, kcal/kg | 5500 |
| Size, mm | 0-50 |
*DO
Long-flame coal DO is a universal fuel. It can be used not only in everyday life, for stoves and boilers, but also in production. The main distinguishing feature of this brand is the absence of large waste:
| Ash, dry basis, max, % | 10.0 |
|---|---|
| Moisture as received, typical, max % | 17.5 |
| Sulphur, dry basis, max, % | 0.6 |
| Volatiles, daf, max, % | 44.0 |
| Net calorific value as received, min, kcal/kg | 5600 |
| Size, mm | 25-50 |
*DPK
One of the most common brands of coal used as a good, easily flammable fuel. It is widely used by the population for heating residential premises, as well as by large boiler houses to obtain heat for the needs of housing services:
| Ash, dry basis, max, % | 10.0 |
|---|---|
| Moisture as received, typical, max % | 17.5 |
| Sulphur, dry basis, max, % | 0.6 |
| Volatiles, daf, max, % | 44.0 |
| Net calorific value as received, min, kcal/kg | 5700 |
| Size, mm | 50-200 |
*LOW VOL PCI (TOMSSH)
One of the most common brands of coal used as a good, but difficult to ignite fuel. The difficult ignitability of coal is fairly well compensated by high heat output and long burning time. LVPCI is widely used by large boiler houses to produce heat for housing services:
| Ash, dry basis, max, % | 12.0 |
|---|---|
| Moisture as received, typical, max % | 12.0 |
| Sulphur, dry basis, max, % | 0.5 |
| Volatiles, daf, max, % | 12.0 |
| Net calorific value as received, min, kcal/kg | 6800 |
| Size, mm | 0-50 |
