Abstract
The calorific values of 16 biomass samples obtained from various Turkish sources were determined experimentally and calculated from both ultimate and proximate analyses. The higher heating values (HHVs) of the biomass samples as a function of fixed carbon (FC) was calculated using the equation HHV = 0.196(FC) + 14.119: the correlation coefficient was 0.9997. The calorific values calculated from this equation showed a mean difference of 2.2%.
