摘      要：Hydrogen is an attractive energy carrier due to the high conversion efficiency and low pollutant *** looping hydrogen production(CLHP)is an available way for producing high purity hydrogen with relatively low penalty energy and CO_(2)is captured *** reactors are usually contained for CLHP system including air reactor(AR),fuel reactor(FR)and steam reactor(SR).In current work,we focus on the performance of CLHP system,which is the basement for operation and *** simulations are carried out for analyzing the flow behavior and the numerical structure is built according to the experimental unit constructed at Southeast University,*** show that the operation of L-valve influences most the solid circulating rate of system and particles pass L-valve easily with large aeration *** distribution results indicate that fuel reactor has the capacity for particles *** of gas inlet rate of steam reactor leads to more particles leave steam reactor and accumulate into fuel reactor.L-valve can prevent the gas leakage between reactors and it will be adopted for reactive *** the operation of fuel reactor and L-valve,the system can reach steady state and get the regulating ability.
