摘要:
仪器仪表是工业领域最常用到的设备之一，对于流程工业有着不可替代的作用。 乙烯裂解炉是乙烯生产装置的核心设备，在炉内进行裂解反应时，裂解温度是最重要的工艺变量，温度的变化对裂解深度、裂解品质有很大影响。 乙烯裂解炉专用热电偶在裂解炉中测量温度，其所处工况 高温、强腐蚀，热电偶容易发生失效。为了对乙烯裂解炉热电偶的失效进行深入的研究，开展硬件故障模式及影响(Failure Mode and Effect Analysis，FMEA)分析，确定乙烯裂解炉热电偶可能的故障 模式及其影响，分析其薄弱环节及敏感应力，从而提出可采取的有效改进和补偿措施，在设计阶段有效提高乙烯裂解炉热电偶的可靠性、稳定性水平。
Abstract:
Instrumentation is one of the most commonly used equipment in the industrial field, and it has an irreplaceable role in the process industry. Ethylene cracking furnace is the core equipment of ethylene production plant. Cracking temperature is the most important process variable when the cracking reaction is carried out in the furnace. The change of temperature has a great influence on cracking depth and cracking quality. The special thermocouple for ethylene cracking furnace is used to measure temperature in the cracking furnace. The working condition is high temperature and strong corrosion, and the thermocouple is easy to fail. In order to conduct an in-depth study on the failure of thermocouples in ethylene cracking furnace, hardware Failure Mode and Effect Analysis (FMEA) was carried out to determine the possible failure mode and influence of thermocouples in ethylene cracking furnace, and to analyze their weak links and sensitive stresses. Effective improvement and compensation measures are put forward to improve the reliability and stability of the thermocouple of ethylene cracking furnace in the design stage.
