摘要

本文采用可调谐二极管激光吸收光谱法 (TDLAS)的波长调制技术, 实现气体温度的测量。考虑到 H2O在大气中、工业生产中普遍存在, 我们选用了 H2O作为测量气体温度的载体, 利用 H2O在 1 397 nm附近谱线对, 通过分析二次谐波信号的峰-峰比值与不同温度的关系, 获得温度测量值, 并通过数值拟合, 分析了在 400～1 100℃温度范围内系统测量的温度误差 (<0.113%)。结合现场结构, 该设备能够用于工业生成过程中的温度监测, 设备性能远优于目前使用的仪器, 能够为燃烧锅炉等生产设备提供准确的温度监控数据。

Abstract

The gas temperature measurement was achieved by using wavelength-modulation spectroscopy technique based on the Tunable Diode Laser Absorption Spectroscopy (TDLAS). Considering that H2O exists in the atmosphere and industrial production, we choose H2O as the carrier gas of temperature measurements. Using the absorption lines near 1 397 nm, according to analysis the relationship between the second harmonic signal peak - peak ratio and temperature, temperature measurements were obtained. Experimental results show that the max error does not exceed 0.113% within the temperature range of 400 ~1 000℃. Combined with the special structure, the device can be used for temperature monitoring of industrial production process. The range of temperature monitoring instrument, the monitoring precision and accuracy is far better than the currently used. The temperature monitoring can provide accurate data for the production equipment of boiler combustion, so as to realize the production efficiency and accurate control, and achieve the ultimate goal of energy saving and emission reduction.
