Experimental study on ash content calorific value of ...

21/02/2020  It was noted that pure coal had 14.28 MJ/kg of calorific value whereas calorific value of charcoal of Prosopis Juliflora prepared using ball mill was 23.83 MJ/kg. From the above results it’s evident that the moisture content in charcoal is very less resulting in higher calorific value, whereas moisture present in Indian coal is about 5%.
