An Experimental Study of Mechanism of Combustion of Carbon in Shallow Fluidized Beds

  • Chapter
Fluidization

Abstract

The mechanism of combustion of carbon in fluidized beds has been studied further by measuring (i) burning rates and temperatures of electrode carbon particles and (ii) burn-out times of batch charges of char particles in an electrically heated fluidized bed combustor at 1073–1173 K. Experimental results showed the inadequacy of the existing models based on diffusion-controlled combustion mechanism. Chemical kinetics and mass transfer of oxygen by forced convection were important controlling influences. Bed design and operating parameters were varied and shown to effect burning rates of carbon in fluidized beds considerably.
