Jhama Coal. Jhama Coal is characterized by high ash, low volatile matter and high fixed carbon. Jhama is usually dull, compact and hard in nature. In India, a large amount of Jhama Coal has been found in the Damodar Valley Coalfields. Jhama is widely used in Lime Manufacturing, Ferro Alloys and Brick Manufacturing units.
Coal for metallurgical enterprises: P CI Coal low volatile with ash up to 10% and 12% ash. Coking coal ZH, KZH, K, highly volatile and medium volatile coal.
On the basis of volatile content, bituminous coals are subdivided into lowvolatile bituminous, mediumvolatile bituminous, and highvolatile bituminous. Bituminous coal is often referred to as "soft coal"; however, this designation is a layman''s term and has little to do with the hardness of the rock.

Low volatile content of the coke means that it needs to be ground more finely in the coal mills in order to ignite and burn in the kiln flame. This requirement for fine grinding can become a capacity constraint on the amount of petcoke that can be prepared for firing in the kiln.
The solid product obtained from carbonization of coal, principally coking coal, at high temperature, it is low in moisture and volatile matter. Coke oven coke is used mainly in the iron and steel industry acting as energy source and chemical agent. Coke breeze and foundry coke are included in this category.
Tests with the baseline coal began on May 2, 1990. Low volatile coal was first burned in mill 11 on May 13 and mil 12 on May 14. A few days were spent documenting 50% low volatile coal operation. Because of the initial success without any problems on low volatile coal, it was decided to proceed to low volatile coal operation.
