Abstract

Experimental study on swirl fluidized bed used 10° angle of blade inclination to dry lignite. This study utilizeda sample of mass 600 gr with a variation of dry air temperature of 50, 45, and 40 °C, and variation of fluidization velocity, which parallel with the gapof 10.9, 13.6, and 16.4 m/s, respectively. The effects of temperature and fluidization velocity difference in drying characteristic and moisture, which released from coal, thus received by dry air were investigated in this study. During the seven minutes of drying for a variation of temperature of 50, 45, and 40 °C, were able to decrease moisture content as much as 24.73, 23.6, and 21.32%, respectively. For a variation of fluidization velocity of 16.4, 13.6, and 10.9 m/s were able to decrease moisture content as much as 22.83, 21.23, and 14.635%, respectively. The amount of moisture which released from coal was not a significant difference with received by dry air.
