Assessment of Coal Quality of Some Indian Coals

Abstract

The rock that we refer to as coal is derived principally from decomposed organic matter (plants) consisting primarily of the element carbon. When coal is burned, it produces energy in the form of heat, which is used to power machines such as steam engines or to drive turbines that produce electricity. Almost 67% of the electricity produced in INDIA is provided by coal combustion. "Coal quality" is the term used to refer to the properties and haracteristics of coal that influence its behavior and use. Among the coal-quality characteristics that will be important for future coal use are the concentrations, distribution, and forms of the many elements contained in the coal that we intend to burn. Knowledge of these quality characteristics in Indian coal deposits may allow us to use this essential energy resource more efficiently and effectively and with less undesirable environmental impact.
