Heat of combustion - Wikipedia

Calorific Value or Heating Value of the Fuel & Moisture ,The 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/ kgThe coal when mined contains moistureWhat is the exact difference between GCV & NCV? - Quora,The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state The heat contained in this water is not recovered The higher calorific value or Gross calorific value (GCV) which supposes that the water of combustion is entirely condensed
