Article Description

Chemical looping combustion (CLC) is a promising technology efficiently utilizing fossil fuels to reduce CO 2 emissions. This work numerically studies the CLC process in a three-dimensional dual circulating fluidized bed (DCFB) using a reactive multi-phase particle-in-cell (MP-PIC) method based on the Eulerian-Lagrangian framework with the discussion of the effects of particle size distribution (PSD) width on bed hydrodynamics and system performance. The PSD is described by a log-normal function. A wider PSD width is produced by adjusting the variation of standard deviation. The results show that the PSD width exerts a significant influence on the physical and thermochemical characteristics, including particle residence time, solid holdup, gas component concentration distribution, chemical reaction rates, oxygen transport efficiency, and fuel conversion rates. A larger PSD width gives rise to a shorter particle residence time in the reactor and enhances the particle exchange and oxygen transport efficiency between the air reactor and fuel reactor. Moreover, the CO 2 yield and the fuel conversion rates are promoted under a larger PSD width.
