摘　　要：循环流化床烟气脱硫技术是近年来国内外正在研究开发的一种先进技术。研究流化床提升管内气固流场分布情况对设计和优化循环流化床脱硫器有重要意义。以循环流化床脱硫器为研究对象,对特定进口装置下的提升管内气固两相流场特性进行了实验研究,以期为循环流化床内气固两相传质、传热的进一步研究及循环流化床脱硫器的工程设计提供参考。Flue gas desulfurization technology with circulating fluidized bed （CFB） has been developed in the world recently. It is valuable for CFB desulfurization reactor design optimization to study the gas-solid flow field characteristic in CFB riser. In order to provide experimental reference for those who would go in for research on process of mass and heat transfer of gas-solid in CFB or CFB desulfurizer design, the effects of inlet-duct on gas-solid flow field characteristic in CFB desulfurizer riser was investigated experimentally.
