摘　　要：针对化学链燃烧制氢中无法实现燃料气的完全转化的问题,本文结合铁氧化物的化学特性提出了一种全新的复合流化床结构,设计搭建了对应热值为50 kW的三联流化床冷态试验台,并对该系统进行了气固流动特性研究,探讨了各反应器送风量对压力特征、固体循环率、物料分布的影响。实验结果表明,反应器的压力随着反应器风量的增大而增大;固体循环率可以在较大范围内调节;整个系统能够长期稳定地运行。A novel compact fluidized bed fuel reactor for chemical looping hydrogen generation is proposed to avoid the incomplete conversion of the fuel gas caused by the thermodynamics limitation, and a cold flow model of three-fluidized bed for chemical looping hydrogen generation corresponding to 50 kW hot units has been built.The effects of flow rate of reactors on the solid mass distribution, pressure characteristic and solid circulation rate were investigated.Results showed that the pressure of reactors increases as the gas flow increase,the solids circulation rate can be adjusted in a wide range and the three-fluidized bed reactor system can run in a steady state.
