FIGURE 7-3. Variation of selected coal properties with coal rank. The chemical approach to characterizing coals is to determine the amounts of the principal chemical elements in them. In the jargon of the coal business, this procedure is called the ultimate analysis of coal. Carbon and hydrogen are the principal combustible elements in coal.

The physical properties of Coal depend on its formation. Physical properties of rocks play an important role in determining its applications in various fields. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Coal is 1-1.5 whereas ...

Burning coal also produces particulates that increase air pollution and health dangers. Burning coal emits large amounts of carbon dioxide into the atmosphere. Coal is composed almost entirely of carbon, so burning coal unleashes large amounts of carbon dioxide (CO 2) into the atmosphere. These emissions have been shown to increase the greenhouse effect in the atmosphere and lead to global ...
