摘　　要：高温气冷堆核电示范工程燃料元件生产线是国家重大专项之一,也是世界首条工业化规模高温气冷堆核燃料元件生产线。低温炭化工艺是球形燃料元件裂解酚醛树脂的关键工艺之一,工作温度为800℃左右。高温气冷堆核燃料元件实验线低温炭化工艺使用原型设备为小规模实验室型电阻加热炉,该设备生产能力低,操作复杂,不适合工业化规模的生产。为满足工业化高温气冷堆核燃料元件生产需求,需要研制一台适合于工业化规模的生产的低温炭化炉。经过设计、安装、调试和生产运行,新设计低温炭化装置各项参数和性能达到了设计要求,可以制备出合格的产品。该设备操作简单,满足了高温气冷堆核电示范工程核燃料元件生产线工业化生产的要求,填补了高温气冷堆核燃料元件低温炭化工艺工业化处理设备的空白。The fuel element production line of the nuclear power demonstration project of high temperature gas-cooled reactor( HTGR) is one of the major national projects. It is also the world’s first industrial-scale nuclear fuel element production line for HTGR. Low temperature carbonization process is one of the key processes for spherical fuel element to crack phenolic resin. The working temperature is 800 ℃. The low-temperature carbonization process of the nuclear fuel element experimental line of HTR uses the prototype equipment of small-scale laboratory-type resistance heating furnace. the device has low production capacity and complex operation,so it is not suitable for industrial-scale production. In order to meet the demand of HTGR,it is necessary to develop a low-temperature carbonization device suitable for industrial-scale production.The parameters and properties of the designed low-temperature carbonization device meet the design requirements. The device is easy to operate,meets the requirements of industrial production of nuclear fuel element production line of HTGR,and fills the gap of industrial processing.
