循环流化床置换燃烧机理介绍及流动特性研究

摘要

Chemical-looping combustion based on circulating fluidized beds offered a novel solution for CO2 separation where no energy was lost. A cold model of circulating fluidized beds for chemical-looping combustion system was built. Several kinds of solid particle were used in the experiments for showing the fluid dynamics of the system. The new approach and new system were founded and a firm basis was established for the next work.%介绍了一种基于循环流化床的动力系统方案———循环流化床置换燃烧。这种燃烧系统能在没有能量损失的前提下，将CO2从燃烧产物中分离出来。本文设计建立了一套燃煤循环流化床置换燃烧冷态实验系统，以此为研究对象，选择具有代表性的实验物料，利用测试系统取得多种信号参数，获得反应装置之间的气固流动特性，总结出一定的规律，为以后的热态实验以及进一步探索奠定基础。
