Abstract

Chemical-looping combustion (CLC) is a new method for the combustion of fuel gas with inherent separation of carbon dioxide. The cold interconnected fluidized beds (Ø100) were set-up for the hot model design in this work. The pressure drop of both air reactor (AR) and fuel reactor (FR) were measured and used for CLC system design. The effects of superficial gas velocity on pressure distribution of both AR and FR were presented. Before fluidization, the pressure drop characteristics of two reactors in interconnected dual fluidized bed for CLC sharply increase with the increasing of gas velocity, which just similar to that of conventional circulating fluidized bed. And after fluidization, the pressure drop of two reactors in dual fluidized bed decreased with the increasing gas velocity. It could be seen that uFR must be increased with an enhancive uAR value to ensure exchange of bed material, and the higher of the gas velocity, the more material could be exchanged.
