How is coal GCV calculated?
GCV = 76.56 – 1.3(VM + ash) + 0.0073(VM + ash)2 In the above equation, VM and ash were in weigh percentage on dry basis and GCV was determined in mJ/kg also in dry basis.

What is the difference between RB1 and RB2 coal?
globalCOAL’s RB1 grade reflects the standard grade of South African export coal with a calorific value of 6,000kc/kg. globalCOAL’s RB2 specification, which rarely trades on the spot market, is for a higher level of volatile materials.
What is RB3 coal used for?
It is no coincidence that South African coal is used in the energy sector and especially in electricity generation. South Africa’s RB1 and RB3 type coals offer high-calorific value and high energy efficiency.
