文章摘要
Fluidization characteristics of quartz particles
with different sizes are experimentally investigated in a
fluidized bed with an inner diameter of 300 mm and height
of 8250 mm. Results show that the average solid holdup
increases with the increase in superficial gas velocity and
the decrease in initial solid holdup in the dense zone of the
fluidized bed. The average cross-sectional solid holdup
decreases with increasing bed height and superficial gas
velocity. The bed expansion coefficient increases with the
increase in superficial gas velocity and the decrease in solid
holdup. Correlations of average solid holdup, average
cross-sectional solid holdup and bed expansion coefficient
are also established and discussed. These correlations can
provide guidelines for better understanding of the fluidization
characteristics.
