Abstract: The caloric value of asreceived coal and that of asfired coal of China Huadian Fulaerji General Power Plant in the first quarter 2009 were compared, and the reasons caused the difference of caloric values of asreceived coal and asfired coal were analyzed. It was found that the main factor influencing on the difference of caloric values is coal moisture. The relevant measures were proposed, and the difference of caloric values of asreceived coal and asfired coal had been controlled in rational range. 

Key words: as-received coal, as-fired coal, net caloric value of as-received basis, gross caloric value of air dried basis, difference of caloric value, total moisture
