Abstract
An experimental study of the thermal decomposition of spherical pine wood particles of different sizes (2–5.6 cm in diameter) has been carried out, using several heating rates of the system. An increase in the particle size produces an appreciable decrease in the weight loss of the solid during the time of its pyrolysis, caused by significant temperature profiles both radial and angular inside the solid. The experimental results have also shown the influence of the particle size and heating rate on these profiles, so that as the particle size and heating rate increase, these profiles become steeper. An analysis of the different values and trends has been performed.
