A dual circulating fluidized bed reactor (riser: 0.04 m × 0.11 m × 4.5 m high; bubbling fluidized bed: 0.285 m × 0.11 m × 2.13 m high) was designed and constructed to investigate hydrodynamics on dual fluidized bed gasifier (DFBG) and chemical looping combustion (CLC). Effects of gas velocities to a riser, bubbling fluidized bed, supply chamber, and recycle chamber as well as vertical aeration rate on solid circulation rate and solids flow characteristics in a loop-seal were determined experimentally. Hydrodynamic characteristics were identified by computational fluid dynamics (CFD) simulation where a two-dimensional (2D) multiphase Eulerian model incorporating with the kinetic theory of solid particles was used.
