RB1 is a premium-grade South African export thermal coal known for its high calorific value, low ash, and low sulphur content, making it suitable for large industrial boilers and power generation plants requiring efficient combustion and cleaner performance. Typical net calorific value is around 6000 kcal/kg NAR or higher.
RB2 is a mid-to-high grade thermal coal offering a balanced calorific value with moderate ash and sulphur levels, making it a cost-effective fuel for industrial users seeking dependable energy output at a more competitive price than RB1. It is widely traded in domestic and international markets.
RB3 is a lower-grade thermal coal with a moderate energy value and slightly higher ash content, providing an economical fuel source for industries where premium coal is not essential. It remains a popular option for budget-conscious buyers.
