Multiphase combustion process of a micro PET (polyethylene terephthalate) resin particle is examined under different heating gas velocities. At higher velocity conditions, thermal decomposition of PET and flash gasification of the decomposed products are prompted near the particle surface, so that luminous flame is formed at an earlier stage of the multiphase process. On the other hand, at lower velocity conditions, duration time of the flame is shortened in spite of longer ignition delay and particle lifetime. This is probably because that partially premixed combustion takes place due to internal bubbling of the particle and resultant abrupt discharge of the flammable gas products.
