The possibility and availability of thermal recycling of recycled plastic resin have been investigated by supplying plastic resin powder as an auxiliary fuel to a proposed industrial twin-fueled burner. The preceding studies clarify the necessity of a series of fundamental investigations such as high-speed microscopic observations of heating and burning processes of a micro plastic resin particle under abrupt heating. In this paper the single mini-puff generator is first devised to extinguish the flame around the micro particle and to cease the heating and burning processes at an arbitrary timing after abrupt heating. The dependency of internal and external appearances of the micro plastic particle on the heating time is then analyzed to clarify the processes of melting, thermal decomposition and gasification, by combining the devised mini-puff generator and the high-speed microscopic observation system.
