(ii) Bituminous (42-83%)- 80% world’s coal output.

(iii) As cooking coal it is used in coke ovens for the manufacture of metallurgical coke, with gas asi| product.

As household coal it is used for domestic heating purposes.

(i) Lignite or Brown coal (38%)- About 15% world’s coal output from lignite.


(ii) Having low heating capacity, it is sometimes used in steel plants.

(iii) Sometime used as fuel in power plants and mainly it is used, as a soil conditioner.
