    thermal coal for power generation and coking coal (for metallurgical coke production). International trade in thermal coals has also maintained high growth, and accounts for an average 17% of global supplies. In 2011, 6 Gt/y of the 7.6 Gt/y of total production was used for power (and some steam/heat) generation (IEA, 2012).

    Thermal Coal – IspatGuru

    Thermal coal is also used in some of the processes for ironmaking especially in the production of direct reduced iron (DRI) and in the smelting reduction processes for the production of hot metal (HM). Thermal coal is a complex heterogeneous substance. Hence, it has no fixed chemical formula. Its characteristics and hence its CV vary widely.
