摘要

为了满足固定污染源在线分析仪器比对和现场环境监督检查的需要，研制了一种基于傅里叶红外(FTIR)光谱分析技术的高温便携式红外气体分析仪。在实验室模拟烟气条件下，采用该分析仪进行SO2和NO标气检测，其示值绝对误差分别小于1.5 μmol/mol和1.0 μmol/mol。该设备在某垃圾焚烧厂的脱硝前烟气进行监测，监测结果的趋势变化与在线监测结果具有较好的对应性，其监测结果平均值的绝对误差在标准容许误差范围内，表明该分析仪具有较好的准确性和现场应用能力，能够满足检测需求。

Abstract

A high temperature portable gas analyzer based on Fourier transform infrared(FTIR) spectroscopy was developed to meet the needs of supervision for on site environment and verification for continuous emission monitoring system of stationary sources.The gas analyzer was used for the detection of SO2 and NO under the condition of simulation exhaust gas in lab

with the absolute errors less than 1.5 μmol/mol and 1.0 μmol/mol for SO2 and NO

respectively.Meanwhile

the equipment was used to monitor the flue gas of a waste incinerator before denitrification.The monitoring results showed a good correspondence with the continuous emission monitoring system(CEMS) results of boiler

and the absolute error for the average value of the monitoring results was within the standard allowable error range

indicating that the analyzer could meet the requirements for on site detection of flue gas with good accuracy and on site application capability.
