Modifiion of Dulong''s formula to estimate heating value
As a result of the evaluation, Dulong''s formula was appropriate for estimating the heating value however, only a limited range of heating values can be determined, because Dulong''s formula was developed for determining heating value of coals, which have unidentified structures. Another reason for the limitation was that the effect of latent heat.
