The considerable diversity of coal type, grade and rank depends on the differences in mode of formation. Black coal is so called because of its colour. It varies from having a bright, shiny lustre to being very dull, and from being relatively hard to soft. The term 'black coal' is used in Australia to refer to anthracite, as well as bituminous ...

Tata, Adani, Lanco to be hit as Indonesia may ban export of low-grade coal Even as Indian power producers were thinking the government had resolved their problems by putting in place a pass-through mechanism for imported coal, there seemed to be another shocker waiting for them, with Indonesia planning to restrict coal exports.The proposed move is likely to jack up generation cost for half a ...
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.
17 rows· Coal Grades. The gradation of non-coking coal is based on Gross Calorific Value (GCV), the gradation of coking coal is based on ash content and for semi coking /weakly coking coal it is based on ash plus moisture content, as in vogue as per notification. Grades of Coking Coal. Grade: Ash Content:

Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.
