摘　　要：对生物质气化-化学链制氢系统进行了试运行分析,在试运行过程中发现生物质气化炉存在排渣不畅的问题,通过加装搅拌辊畅通排渣;生物质气化炉点火初期,未达标合成气采用了外排引燃的处理方式,消除了潜在的环境污染风险;系统冷、热态气密性检测中漏点难以定位的问题,通过在管路中增设取样点配合检测氧气浓度,为漏点定位提供数据支撑;气化炉出现温度偏低的情况,通过改进点火方法使炉温明显提高;生物质气化炉运行过程中,产生的生物质油凝结在合成气引风机叶片及罩壳上,停机后再启动易造成设备过载,采取停机前蒸汽冲洗的方法解决。A trial operation analysis of a biomass gasification⁃chemical looping hydrogen generation system is conducted.In the trial opeation,it is found that the slag discharge of biomass gasifier is not smooth,which is solved by adding stirring roller.At the initial stage of ignition of biomass gasifier,the substandard syngas is treated by exhaust ignition,which eliminates the potential environmental pollution risk.The problem that the leak point is difficult to locate in the cold and hot air tightness detection of the system is solved by adding sampling points in the pipeline to detect the oxygen concentration,which provides data support for the leak point location.The temperature of gasifier is low,and the furnace temperature is obviously raised by improving the ignition method.During the operation of the biomass gasifier,the biomass oil produces condenses on the blades and cover of the synthetic gas induced draft fan,which is easy to cause equipment overload when restarted after shutdown,and the method of steam washing before shutdown is adopted to solve the problem.
