“…However, conventional probing methods are not sensitive to detecting the small differences between the optimal design process and various operating conditions. Regarding the thermochemical parameters, temperature and CO 2 concentrations are two key parameters that are strongly related to combustion efficiency and carbon emission 4–6 . Thermocouples are frequently used for flame temperature measurements due to its operation convenience and relatively low cost 7 .…”

A mid-infrared laser absorption tomography technique was developed to quantify the nonuniform thermochemical structures of flames stabilized on a natural gas-fired cooker. Multispectral absorption spectroscopy coupled with Tikhonov-regularized three-point Abel inversion was used to resolve the spatially resolved temperature and species concentration. A tunable interband cascade laser (ICL) near 4.2 μm was used to access multiple CO 2 absorption lines in the fundamental vibration band. Multiline Voigt fitting strategy was used to improve the fitting of the overlap absorption features. Comprehensive measurements at a different height above the cooker were performed and assembled to display the contour of temperature and CO 2 concentrations, resolving the nonuniform thermochemical structure of the high-temperature combustion field. The measurement uncertainty analysis for temperature and CO 2 concentration was also discussed. The current technique is demonstrated to be capable of quantitatively distinguishing flame conditions under different fuel supply modes.
