Strongly caking
coals of
Cement Sector :
The sulphur content to the extent of 5% is a burn for the clinker formation technology.

Used in ACC, CCI, Bokajan Cement factories.
Power Sector :
The best way to utilize NEC coal will be by fluidised bed combustion in Power Plant located centrally in the mining area
