Coals are an important source of energy, as well as being essential for the production of metallurgical cokes, and are widely used as feedstock for other industrial processes such as in the production of gaseous fuels and synthesis gas. Hence, aCoal | Types of Coal: Peat, Lignite, Bituminous Coal,,01/03/2011· Thus, there is no universally accepted criterion for any precise classification of coals with respect to their proneness to spontaneous combustion and the degree of their shift from one coal to other.

This paper presents an investigation into the application of hierarchical clustering method for classification of coal seams with respect to their spontaneous heating susceptibility. In this research work, 31 coal samples were collected from different Indian coalfields covering both fiery and non-fiery coal seams of varying ranks spreading over 8 different mining companies. Proximate, ultimate,What are the different types of coal? | American,,The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or “ranks,” of coal are determined by carbon content.Fire Ladder Study to Assess Spontaneous Combustion,,Panigrahi, D.C., Sahu, H.B.: Classification of coal seams with respect to their spontaneous heating susceptibility—a neural network approach.
