Bituminous coal (brown coal)

According to its characteristics, it is the best of all grades of Lignite, and comes close to the slow and long burning coals. It has low ash content (up to 18%), and about the same internal humidity (18%). Furthermore, the coal contains a large amount of volatile substances (50%) and thereby it is quickly ignited and burns well.


HDS Hammer Crusher. Double-shaft hammer crushers are mainly used in the cement industry for the comminution of soft to medium-hard, but also moist and tough materials: Limestone, gypsum, chalk, clay and marl, as well as lignite and pit coal. The crushing of the feed material is effected by percussion, impact and shear forces. Equipment. Equipment.


In time, material that had been plants became coal Coals are classified into three main ranks, or types lignite, bituminous coal, and anthracite These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal Coal is defined as a readily combustible rock containing more than 50 by weight of carbon.

What Is The Chemical Composition Of Bituminous Coal? Bituminous coal has a composition of about 84.4% carbon, 5.4% hydrogen, 6.7% oxygen, 1.7% nitrogen, and 1.8% sulfur, on a weight basis.This implies that chemical processes during coalification must remove most of the oxygen and much of the hydrogen, leaving carbon, a process called carbonization.

The characteristics of the Eastern Bituminous and on-site blended coals are summarized in Table 1.


How Is Coal Refined? Refined coal is most commonly made by mixing proprietary additives to feedstock coal.These additives increase the production of mercury oxides, which can then be captured by using mercury emission reduction technologies such as flue gas desulfurization scrubbers and particulate matter control systems.
