Gas-solids interactions in the distribution zone of a fluidized bed. Phase I. Quarterly report, June 15--September 15, 1976
1976
A miniature, self-heating mode thermistor probe was developed, tested and used to probe the distribution zone of a 60-micron solids fluidized bed to define the interfaces between gas jet; fluidized; moving, but not fluidized; and non-moving regimes of the distribution zone of a fluidized bed. Probings were completed in a 5.2-in.-I.D. reactor with gas entry velocities of 100 and 200 fps with respective superficial velocities of 1 and 2 fps. A 3.4-in.-I.D. reactor was probed with gas entry velocity of 100 fps and superficial velocity of 2 fps. Data from these probings will be used to generate three dimensional interfaces for the several solids regimes.
