Investigations of the Ultimate and Proximate Analysis of Coal Samples From the Singrauli Coalfield, India

Coal is a mixture of heterogeneous sedimentary rock materials; it includes organic and inorganic constituents. The utilisation potential of any coal depends on its chemical constituents, and the gross calorific value defines its usefulness in thermal power generation and other industries. In this study, we collected non-coking coal from the Singrauli coalfields region in India. These coals have been analysed for proximate and ultimate analysis and GCV (gross calorific value). The grade of coal varies from G6 to G9. De-ashing and clean coal technology are required. This study will reveal the reasons for grade variation in coal, which will be useful in thermal power industries.
