Simultaneous heat and mass transfer between a fluidized bed of fine particles and immersed coarse porous particles

Innovative Energy‐Efficient Biomass Drying Based on Self‐Heat Recuperation Technology

“…The interparticle heat transfer coefficient from the inert particles to the sample in the dynamic regime has been described by Cobbinah et al [30] …”

“…An approximation of heat exchange based on previously conducted research [30,[33][34][35][36] was performed to evaluate the kinetics of the heat transfer rate occurring inside the FBD and to approximate the required length, L, of the heat transfer tube inside the FBD. This was also important for predicting the feasibility of heat exchange in the proposed drying system.…”

“…The involvement of the inert medium also reduces the blower duty providing the pressure difference required for fluidization due to their particle size being smaller than the biomass sample. In addition, the inert medium increases the heat transfer rate and its temperature uniformity across the bed, resulting in high and uniform drying rates [25,29,30].…”

“…The heat transfer between particles, i.e., the fluidizing medium and EFB particles, in the dynamic regime is approximated using the following equation [36]. Fig.…”

Mass Transfer around Active Particles in Fluidized Beds

“…Up to now the only works available in the literature where this technique was applied to few freely moving active particles within a fluidized bed of inert particles are those reported by Vanderschuren & Delvosalle (1980) and Delvosalle & Vanderschuren (1985), and by Cobbinah et al (1987). The first authors estimated with the aid of a simple model the mass transfer coefficient in beds of refractory silica and alumina particles, where wet particles were dried in beds of dry particles of the same material and size.…”
