Sinopsis

An experimental investigation on the flow characteristics and heat and mass transfer between coarse particles and hot gas in circulating fluidized bed were performed. The sand of 450 µm in diameter with initial moisture content of 0.05-0.2 kg/kg was used as wet material in the test. The influence of air superficial velocity, solid rate and initial moisture content on heat and mass transfer were examined. The heat and mass transfer correlations for wet coarse particles in CFB were obtained.
