%X In order to develop the advanced flue gas desulphurization (FGD) technology, a cold circulating suspension bed facility with a cross section of 400 mm400 mm was built. Air and glass granules with a mean diameter of 40 mm were used in experiment. A dual-optic density probe was used to measure the particle concentration and distribution changes with bed parameters, such as air jet entrance at the bed bottom, top structure and inner structure, superficial air velocity, circulating flow rate. The influence of some factors on the wall and corner particle back-flow was analyzed too. The experimental results show that it is necessary to optimize the geometrical configuration and choose suitable working parameters of the circulating suspension bed to improve desulphurization efficiency.
