Abstract

Chemical looping combustion (CLC) is a novel combustion method for CO2 capture. A cold model of an interconnected fluidized-bed system for CLC was designed and operated, in which the loop seal was used to balance the pressure difference and prevent gas mixing between the fuel reactor (FR) and air reactor (AR). The effects of the operating parameters on solid circulation rate, pressure profiles, and solid distribution are investigated. The experimental results indicate that high solid circulation rates between the FR and AR can be achieved and provide a wide range of stable operating conditions. No gas leakages between the FR and AR are detected. The suitable operating conditions are optimized for the cold model of CLC which could pave the way for further design, improvement, and operation of the hot prototype.
