Design Aspects of Bubbling Fluidised Bed Boiler for

The bed of solid particles exhibits the properties of a boiling liquid and assumes the appearance of a fluid "bubbling fluidized bed". At higher velocities, bubbles disappear, and particles are blown out of the bed. Therefore, some amounts of particles have to be recirculated to maintain a stable system "circulating fluidized bed".

Simulation of Coal and Biomass Cofiring with Different

A 2D dynamic model for a bubbling fluidized bed (BFB) combustor has been developed for simulating the coal and biomass cofiring process under 21% O 2 /79% CO 2 atmosphere in a 6 kWth bubbling fluidized bed, coupled with the Euler-Euler two-phase flow model. The kinetic theory of binary granular mixtures is employed for the solid phase in order to map the effect of particle size and density.

Numerical simulation for fluid dynamics in a gas-solid

A comprehensive two-dimensional model was developed for studying dynamics in a gas—solid bubbling fluidized bed. In the model, gas and solid phase are treated as two interpenetrating continua. So a two-fluid model is presented. And a software model which is used to simulate the bubble frequency, the bubble velocity and the bubble length is added into CFD software.
