内容記述 |
A semi-cylindrical fluidized bed 15 cm in diameter, equipped with a transparent flat glass plate for the front wall, and a perforated plate distributor with 7 holes in a lineat pitch, was employed to visually observe bubbles in a fluidized bed. Bubble size and bubble rise velocity were measured for each well formed bubble by observation through the front window. The experimental conditions were as follows : four kinds of sand were used ( average particle size d_p=75, 189, 281 and 521 μm ) at excess gas velocities above minimum fluidization of 8, 12, 25 and 35 cm/s. The static bed height was 70 cm for all experiments. No effect of particle size on bubble behavior was detected. The average size of bubbles was well represented by Darton et al.'s model. The average velocity of the bubbles was in agreement with the model of Allahwalla and Potter. Each of these models was developed for three dimensional fluidized beds. |
