The agreement for temperature between experiments and calculation results was good; however, improvement of accuracy of the moisture content measurement system and investigation of influence of grains of wood were needed because quantitively comparison was difficult by difference of time variation of moisture content at the same heat strength. Closer to unheated surface, difference between experiments and calculation results of moisture content became larger. In addition, modeling of the process of char oxidation and mass decrease and improvement of adsorption- isotherm will be necessary because temperature increasing was a bit slower and the maximum value of moisture content in experiments was bigger than maximum values of adsorption-isotherm.
