由于采用非均匀布风 ,内旋流流化床的移动区空气量不足 ,导致燃烧不充分 ,温度较低。当移动区未流化时 ,密相区内存在较明显的温度不均匀性。随着移动区流速的提高 ,温度差迅速减小。当移动区流速超过 2 .0 umf后 ,密相区温度基本均匀一致。流动区流速对密相区温度均匀有一定的影响 ,流速越高 ,温度越均匀 As a result of non-uniform air distribution, the inner swirling fluidized bed air volume is insufficient, resulting in inadequate combustion, the temperature is low. When the moving zone is not fluidized, there is a more pronounced temperature inhomogeneity in the dense zone. As the flow rate in the moving zone increases, the temperature difference decreases rapidly. When the mobile area flow rate exceeds 2.0 umf, the dense zone temperature is basically the same. The velocity of the flow zone has a certain effect on the temperature uniformity in the dense phase zone. The higher the flow rate, the more uniform the temperature
