摘要
Abstract
In the circulating fluidized bed ( CFB ) cold model test system, a study on the relationship between operating conditions and gas-solids flow characteristics were carried out in a new returning ash heat exchanger. By changing the air flowrates of air-equalizing chamber and back-feed chamber,supplying air in radial direction in standpipe, the gas-solid flow characteristics of back-feed system under different operating conditions were analyzed. Cold test study results showed the relationship between different operating conditions and gas-solids flow characteristics in the returning ash heat exchanger, obtained from the air flowrates of each air chamber and the parameters of radial air supply for standpipe.关键词
