抄録

There is growing interest in the use of waste woody biomass as an alternative fuel to coal, because of its carbon neutral as an effective use of waste resources. To compensate for the low calorific value of biomass resources, we focused on biochar prepared by the lower-temperature pyrolysis. As the results, the calorific values and combustion conditions were improved to the same level as the used coal. Furthermore, the emissions of toxic polycyclic aromatic hydrocarbons (PAHs) in PM_2.5 and PM₁₀ emitted during coal combustion were found higher than those of biochar. In the future, we would like to quantitatively evaluate PAHs generated in the entire processes, including during biochar preparation.
