Coking Coal
These coals, when heated in the absence of air, form coherent beads, free from volatiles, with strong and porous mass, called coke. These have coking properties Mainly used in steel making and metallurgical industries Also used for hard coke manufacturing
Semi Coking Coal
These coals, when heated in the absence of air, form coherent beads not strong enough to be directly fed into the blast furnace. Such coals are blended with coking coal in adequate proportion to make coke. These have comparatively less coking properties than coking coal Mainly used as blend-able coal in steel making, merchant coke manufacturing and other metallurgical industries
Non-Coking Coal
These are coals without coking properties. Mainly used as thermal grade coal for power generation also used for cement, fertilizer, glass, ceramic, paper, chemical and brick manufacturing, and for other heating purposes
Ltc Coke
LTC Coke(CIL Coke) is a smokeless, environment friendly product of the Dankuni Coal Complex, obtained through low temperature carbonisation. Used in furnaces and kilns of industrial units Also used as domestic fuel by halwais, hotels, etc.
COAL FINES / COKE FINES
These are the screened fractions of feed raw coal and LTC coke (CIL coke) respectively, obtained from the Dankuni Coal Complex and other coke oven plants. Used in industrial furnaces as well as for domestic purposes
TAR / HEAVY OIL / LIGHT OIL / SOFT PITCH
These are products from Dankuni Coal Complex using low temperature carbonisation of non-coking coal in vertical retorts. Used in furnaces and boilers of industrial plants as well as power houses, oil, dye, pharmaceutical industries, etc.
The table below sets forth the various gross calorific value (GCV) based bands of non coking coal .
