Steam coal

Steam coal with size up to 50 mm is used not only for burning at power-and-heating (Power Utilities, IPP and boilers) but also at sugar plants, chemicals and in the cement industry. Low level of ash, sulfur, chlorine and phosphorus and at the same time high level of calorific value are unique characteristics of steam coal sold by MIR Trade AG. Our company permanently increases an assortment of steam coal to meet requirements of our buyers by regulating such parameters as ash, moisture, volatiles, NCV.
The volume of steam coal sales makes more than 70% of the total sales of MIR Trade AG.
