The calorific value of brown coal ranges from 14.500 – 21.000kJ/kg.
DRVOSJEČAs hard coal is produced in CUBE AND WALNUT granulation.
The cube is 25-50mm in size, while the nut is 15-25mm. The coal is well separated, so there is no coal dust. We have our own truck scale within the company, and we weigh every delivery of coal! Along with the delivery, the customer receives a weighing sheet that serves as a guarantee for the delivered quantity!
When the coal is delivered it is wet because it has undergone wet separation in the mine and needs to be dried with proper storage.
