Prosperities of Bituminous Coal
-
Bituminous coal has moisture content up to 17%.
-
Approximately 0.5 to 2% of the weight of bituminous coal is nitrogen.
-
Its fixed carbon content ranges up to 85%, with ash content up to 12% in weight.
-
The calorific value of bituminous coal A is 8 – 10% about 6,300 – 7,000 kcal/kg while that of medium volatile bituminous has 7,000 – 8,000 kcal/kg.
-
Bituminous coal can be further divided by the level of volatile matter it consists of, like high-volatile A, B, and C, medium-volatile, and low-volatile.
-
Volatile matter takes into account any material that is free from the coal at high temperatures.
-
In the context of coal, the volatile matter may include sulfur and hydrocarbons.
