The possibility of thermal recycling of recycled PET-resin for industrial burner systems has been investigated both in the in-furnace and the open atmospheric operations by supplying PET-resin powder as an auxiliary fuel to the improved commercial LPG-fueled ceramic burner. These results showed that a large part of PET-powder is exhausted without burn-out in the open atmospheric operation, whereas it is perfectly consumed in the in-furnace operation. In this paper, in order to reduce an amount of unburnt PET-particles in the open atmospheric operation, reactive flow and burning processes of PET-particles are investigated using PIV/PTV measurements. Appearances of flying PET-particles are also observed using the pulse laser and the particle diameter are evaluated by calculating the equivalent diameter. According to the results, key factors for effective bum-up of PET-particles are finally discussed.
