How to read a coal analysis
Two coals at the same price can be very different buys. The analysis tells you which one gives more heat for your money.
Heat value (kcal/kg)
The calorific value is the energy in one kilogram of coal. Higher is better. Balochistan coal runs from about 4,500 kcal/kg for fines to about 7,000 for the best Sor Range.
To compare offers, divide the price per tonne by the heat value: the lower the result, the more heat each rupee buys.
Ash
Ash is what is left after the coal burns. More ash means less heat per tonne and more to clear out. Sor Range is lowest; fines and Mach / Harnai are highest.
Moisture
Total moisture is water you pay for but cannot burn. Check whether the figure is 'as received' (as delivered) or 'air-dried', which is lower.
Sulphur
Sulphur turns into fumes and corrodes boilers. All Balochistan coal is fairly high in sulphur, usually 3 to 6%; Sor Range is lower at 2 to 4%.
Volatile matter and fixed carbon
Volatile matter is the part that burns off as gas and helps the coal light. Fixed carbon is the solid fuel that burns after. Together with ash and moisture they make up the whole sample.
Prices are indicative, per tonne, excluding sales tax, and change week to week. See today's sheet or ask us for a confirmed price.
