What is 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 high CV thermal coal?
Thermal coal is a type of bituminous coal which is used to provide heat energy in combustion in various types of furnaces via the pulverized fuel method because of its high calorific value (CV). It is also sometimes called as non-coking coal, steam coal, or boiler coal.
What is kcal/kg coal?

What is the difference between thermal coal and metallurgical coal?
Metallurgical coal (or “coking coal”) is mined to produce the carbon used in steelmaking, while thermal coal is used to make steam that generates electricity.
What is GCV and NCV of coal?
The “Effluent Treatment” laboratory is equipped with a calorimeter, which is used to determine gross calorific value (GCV). The hydrogen content of the fuel is then measured in order to calculate net calorific value (NCV).
What is washery grade coal?
Coking coal having less than 18 per cent ash is termed steel grade coal which can be used directly by consumers in the steel sector. Coal having higher ash content (18 per cent to 35 per cent) is termed washery grade coal and requires washing to make it suitable for use in production of steel.
