Low-caking

Quality Ccharacteristics for low-caking coal, grade SS

Grade SS coals are characterized by volatile content of 20% to 32%. Common uniting feature for them is low-coking or complete lack of it. Moisture of freshly mined coal grade SS reaches 8-9%. Ash content ranges from 8 to 25%. The sulfur content is typically less than 0.8%. The carbon content ranges from 74 to 90%. Coal grade SS is mainly used by large power plants and in domestic household.

We recommend that you use low-caking coal in iron and cast iron boilers or in stone bread oven by natural and poor draught.
