Oct 07 2019 Calorific value is a measure of the amount of energy produced from a unit weight of coal when it is combusted in oxygen. A measured sample of coal is completely combusted in a bomb calorimeter which is a device for measuring heat ASTM method D5865-12 American Society for Testing and Materials 2013 p. 648666.

Environmental impact of coal industry and thermal power

The problems associated with the use of coal are low calorific value and very high ash content. The ash content is as high as 55-60 with an average value of about 35-40. Further most of the coal is located in the eastern parts of the country and requires transportation over long distances mostly by trains which run on diesel.
