A two-thermocouple contrast method was developed to measure the local gas and solid temperature along the height of the bed. The influences of air superficial velocity, solid rate and initial moisture content on the local heat and mass transfer between gas and solid were examined. The correlations of heat and mass transfer coefficients between gas and coarse wet particles in CFB were obtained.展开更多
文摘An experimental investigation on the flow characteristics and the local heat and mass transfer between coarse wet particles and hot gas in the circulating fluidized bed (CFB) has been performed. A two-thermocouple contrast method was developed to measure the local gas and solid temperature along the height of the bed. The influences of air superficial velocity, solid rate and initial moisture content on the local heat and mass transfer between gas and solid were examined. The correlations of heat and mass transfer coefficients between gas and coarse wet particles in CFB were obtained.
