为测量乙烯裂解时的炉内温度,设计一种双陶瓷管封装的飞秒光纤布拉格光栅(FBG)高温传感器.在分析飞秒FBG温度传感器测温原理的基础上,推导出用于高温环境下测温用的拟合多项式.根据乙烯裂解炉目前测温状况,设计用于高温环境下的双陶瓷管式飞秒FBG传感器及配套的安装结构.利用Ansys有限元分析软件记录外界温度变化与FBG传感器的温度响应时间.仿真结果表明,双陶瓷管式封装的飞秒FBG温度传感器的温度响应时间能够满足乙烯裂解炉实时测温的需要.
Design and finite element analysis of ceramic tube femtosecond FBG high temperature sensor
In order to measure the temperature in the furnace during ethylene cracking,a femtosecond fiber Bragg grating(FBG)high temperature sensor packaged with double ceramic tubes is designed.On the basis of analysis of the temperature measurement principle of femtosecond FBG temperature sensor,the fitting polynomial for temperature measurement in high temperature environment is derived.According to the current temperature measurement situation of ethylene cracking furnace,a double ceramic tube femtosecond FBG sensor and its supporting installation structure are designed for high temperature environment.The Ansys finite element analysis software is used to record the external temperature change and the temperature response time of the FBG sensor packaged.The simulation results show that the temperature response time of the femtosecond FBG temperature sensor packaged with double ceramic tube can meet the needs of real-time temperature measurement of ethylene cracking furnace.
