An optical fiber probe system is developed for the measurements of solids concentration and bubble properties. A TCD gas tracer system is available for the studies of gas dispersion and backmixing. This study explored the possible combinations to produce desirable fluidization properties under operating conditions of commercial processes. The purpose of this project is to identify operating ranges of low gas dispersion for heterogeneous gas-phase oxidation processes. This project examined the general fluidization behavior of these particles, and interparticle forces effects.
Liquid injection is used for heat removal.
This study examined the effects of liquid contents on fluidization behavior, and the maximum acceptable liquid content for normal operations of a fluidized bed. L-valve is used for solids recirculation. Many instruments developed for bubbling fluidized beds are available for the studies in the circulating fluidized bed system. Measurements of particle transfer in the radial direction has also been carried out in the dilute region. Assessments of circulating fluidized bed reactors including coarse particle and baffle effects on the reactor performance, using ozone decomposition as a model reaction.
