چکیده

As most classical fluidization technologies, Circulating Fluidized Beds (CFB) are widely employed in chemical and physical operations. However, CFB Reactors still have some disadvantages such as the non-uniform solid particles distribution backflow of near wall, which deteriorate system mixing, lead to low conversion/heat mass transfer rate. To improve performance, we propose current work study effect ring baffle configuration on hydrodynamics using a multifluid Eulerian CFD model, incorporating Kinetic Theory Granular Flow. In this approach, two different types baffles, circular trapezoidal, were considered corresponding results compared. The revealed that incorporation baffles improved mixing reduced wall. Nevertheless, shape had limited impact hydrodynamics.

Modeling and Numerical Simulation of Liquid-solid Circulating Fluidized Bed Systems

A novel liquid-solid circulating fluidized bed (LSCFB) is modelled for protein recovery from feed broth. A typical LSCFB system consists of two individual columns (downer and riser), integrating two different operations (adsorption and desorption respectively) simultaneously with continuous adsorbent circulation between these columns. A general purpose, extensible, and dynamic model was written...

Cluster Dynamics in a Circulating Fluidized Bed

A common hydrodynamic feature in industrial scale circulating fluidized beds is the presence of clusters. The continuous formation and destruction of clusters strongly influences particle hold-up, pressure drop, heat transfer at the wall, and mixing. In this paper fiber optic data is analyzed using discrete wavelet analysis to characterize the dynamic behavior of clusters. Five radial positions...

Investigation of a Cold Model of Internally Circulating Fluidized Bed with Draft Tube to be used as a two-Zone Fluidized Bed Reactor

In this research, a cold model of internally circulating fluidized bed is investigated. The aim is to find the effects of some of the operating parameters on the performance of the reactor. Experiments were carried out in a glass column (30 mm i.d. and 25 cm height) with a centrally located draft tube (11 mm i.d. and 5 or 7 cm height). The bed was loaded with white silica particles (dp = 0.15 -...
