Measurement of Carbon Dioxide Concentration in Flame Using Near Infrared Laser Absorption Spectroscopy

Dong Chen

Abstract

Tunable diode laser absorption spectroscopy (TDLAS) technology is a new method to detect trace gas quantitatively based on the wavelength tunable character of diode laser to obtain the absorption spectroscopy in the characteristic absorption region. It is an ideal method for trace gas detection and industrial combustion control due to its advantages of high sensitivity, high selectivity, quick response, on -line measurement. The experiment method of measuring concentration of carbon dioxide in flame and removing light-intensity in combustion are introduced, and the result obtained is comparably good.
