RB2 coal is a mid-grade thermal coal primarily sourced from South Africa, valued for its balance of energy content and cost-effectiveness. It is widely used for power generation and various industrial processes like cement and brick manufacturing. Key characteristics include a high calorific value (
5,5005 comma 500
kcal/kg), moderate ash content (
18−2018 minus 20
% ), and good combustion properties, making it a versatile and efficient fuel source.
