| Abstract: | A batch combustion model of carbon particles in a spouted bed has been developed based on the concept of carbon residence time in each region of the spouted bed (annulus, spout and fountain). Both isothermal and nonisothermal particles are considered, with the assumption of no temperature gradient inside the particle. Model predictions in terms of carbon conversion and burnout time were in good agreement with experimental data obtained from a laboratory scale spouted bed combustor. For comparison, an experimental study on a spout-fluid mode was also carried out. |
