Abstract
The possibility and availability of thermal recycling of recycled plastic resin have been investigated by supplying plastic resin powder as an auxiliary fuel to the proposed industrial twin-fueled burner. The preceding studies clarify the necessity of a series of fundamental investigations, such as high-speed magnifying observations of ignition and burning processes of frying micro plastic particles passing through combustion zone of the two-dimensional premixed flame. In this paper the tracking system composed of a pair of synchronized rotating plane mirrors is first devised to pursue simultaneously some micro particles in their long paths through the flame zone. By combining the devised tracking system with the high-speed video camera and by taking account of the flow patterns measured by the PIV/PTV system, effects of the particle diameter, the particle frying speed, and the relative velocity between the particle and gas velocity on the ignition and burning processes of macro particles are examined.
