| 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. |
