    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 D586512; American Society for Testing and Materials, 2013, p 648–666)Chemical composition of the coal is defined in terms of its proximate and ultimate (elemental) analyses The parameters of proximate analysis are moisture, volatile matter, ash, and fixed carbon Elemental or ultimate analysis encompasses the quantitative determination of carbon, hydrogen, nitrogen, sulfur and oxygen within the coal Additionally, specific physical and mechanical properties of coal and particular carbonization properties Energy value of coal WikipediaThe Calorific Value varies on the geographical age, formation, ranking and location of the coal mines It is expressed as kJ/kg in the SI unit system Power plant coals have a Calorific Value in the range of 9500 kJ/kg to 27000 kJ/ kg The calorific value is expressed in two different ways on account the moisture in the coalCalorific Value or Heating Value of the Fuel Moisture Content:
