Abstract
A model of HYL-III top reactor with its feeding bin called UFO, has been built to investigate size segregation phenomena in the top part of the reactor. The model was one tenth of the actual size, both for the equipment and the material used in the experiment. To give more comprehensive overview of the investigation, a prediction of segregation in the HYL-III reactor feeding system was also done at each of the main equipment in the system. Some factors that may affect the size segregation which were observed in this study are size distribution of the material, solids flow rates and the charging and discharging mode. Two kinds of material size distributions, two kinds of solids flow rates, five kinds of UFO model charging modes and two kinds of UFO model discharging modes were investigated. To understand the effect of size distribution on the particle segregation, two kinds of materials were used, i.e. one that was close to the actual concentration of large and small particles + and the other that each size range has an equal concentration. The effect of solids flow rates was investigated by discharging the UFO model in a low and high solids flow rates. Five charging modes were investigated to understand their effect. The effect of discharging mode was measured by blocking one of the UFO model legs.
