摘要
以某4×1 036MW机组的氢气供应系统为例,介绍了氢气供应系统的组成及设备状况。当储氢罐需检修时,应进行检修前和检修后的置换操作。在置换操作过程中,易产生各种影响设备安全的危险因素。为此,提出了相应的预防措施和对策。通过分析,为防止危险的发生,提出了有益的建议,并在储氢罐的置换操作中得到实施,确保了机组的稳定运行。
Taking the hydrogen supply system in certain 4 ×1036 MW units as an example, this paper introduces the equipment of the hydrogen supply system and equipment conditions. Replacement operation shall be conducted before and after the hydrogen storage overhaul. Risk factors that affect the safety of the equipment occur during the replacement operation process. The corresponding prevention strategies and approaches are presented. Useful suggestions have been put forward to prevent accidents through analysis, and have been carried out in the replacement process of hydrogen storage tank, which ensured the stable operation of the unit.
