Аннотация

A relationship between the exergy and HVs (heating values) of a fuel bridges a way for estimating the exergy of the fuel. Based on the ash exergy characteristics of sixty four woody biomass investigated in this study, a new equation based on the HHV (higher heating value) and ash exergy is then proposed for estimating the exergy of woody biomass. This new equation has two advantages: (a) avoids the cumbersome work involved in calculating the ash exergy, and (b) cuts the extra work for transferring HHV to LHV (lower heating value). The results obtained from this study also show that the relative errors between the estimated and calculated wood exergy values are mainly between -0.754% and 0.986%, the new equation proposed in this study can therefore be well used for expeditious estimation of the exergy of woody biomass with high accuracies.
