Abstract
In order to burn plastic-resin powder as an alternative fuel and to realize effective energy-recycling of recycled plastic-resin, it is necessary to elucidate fundamental characteristics of a plastic-resin particle subjected to abrupt heating. The abrupt heating method using a CO_2-gas laser as a heat source is employed in this study. High-speed microscopic observations of physical and chemical processes of a plastic-resin particle after abrupt heating are made by combining a microscope with a high-speed CCD video camera. Heating and burning properties of a micro plastic-resin particle are discussed and compared with those estimated by a simplified spherically one-dimensional analysis.
