The possibility and applicability of thermal recycling of recycled PET-resin for the industrial burner systems have been investigated by supplying PET-resin powder as an auxiliary fuel to the improved commercial LPG-fuelled ceramic burner. The results showed that a large amount of PET-powder up to 80% is exhausted without burn-up in the open atmospheric operation, whereas it is perfectly consumed in the in-furnace operation. In this paper, in order to obtain key reasons why a large amount of PET-powder is exhausted without burn-up in the cold open atmospheric operation of the industrial burner and to reduce the amount of the unburnt PET-powder, the interrelation between the flow patterns and the dispersion profiles of PET powder in and downstream of the burner is examined by employing the PIV/PTV system. Appearances and diameters of PET particles flying through the combustion zone downstream the stabilizer are also observed using the proposed technique. According to the results, three factors having great influences on the unburnt rate of PET-powder are found.
