“…To the best of our knowledge, this is the first report applying this spatial and temporal resolved method to metalorganic single droplet combustions. Studies including spatially resolved flame emission spectroscopy have been reported for particle combustion, 32,33 flame combustions [34][35][36][37] and for pyrotechnic combustion behaviour (temporal and spatial). 38 Previous studies have analysed the combustion of metalorganic precursors using high-speed imaging, revealing mass transfer and phenomenological combustion behaviours/ mechanism such as micro explosions.…”

“…Transmission/absorption of flame regions using FTIR is usually not possible due to high optical density of the sample region, strong emission of infrared radiation from the flame, and low spectral radiance of the incoherent sources used for transmission. FTIR emission spectroscopy has been used to measure CO, H 2 O, and temperature in biomass burning flames [16], yet it is difficult to obtain quantitative results and measure trace species with this method.…”

“…There are relatively few reports in the literature on the spectral emissivity of a biomass combustion flame. Tree et al 40 recently examined the radiation characteristics of natural gas and biomass combustion flames through emission spectra using Fourier transform infrared (FTIR) spectroscopy; the effective spectral range of the measurements was 1350−2200 nm. In this range, the effective emissivity of the wood particle luminous flame was 0.17.…”

In this paper, a method for the simultaneous measurement of the flame temperature and emissivity using spectral thermometry and image thermometry was proposed; experiments were conducted using a laboratory furnace burning solid particle fuel derived from biomass. First, a non-gray emissivity model with a third-order polynomial function was established, and the accuracy of the temperature estimates obtained from the gray emissivity model, the non-gray emissivity model, and the Hottel and Broughton emissivity model was determined. The results showed that the proposed non-gray emissivity model had the highest accuracy and the maximum relative error compared to the thermocouple measurements was less than 1.5%. Second, the spectral emissivity obtained from the spectral thermometry was used to correct the image pyrometer data. The two-dimensional distributions of the flame temperature and emissivity are measured after correction using image pyrometry. It showed that the results of the spectral thermometry and image thermometry were highly consistent with the thermocouple measurements and the maximum relative errors were 1.5 and 3.2%, respectively. Finally, the effects of the equivalent ratio on the temperature and spectral emissivity were investigated. The results showed that the maximum temperature of the volatile combustion flame was 1000–1250 K and the maximum emissivity of the flame ranged from 0.05 to 0.25 in the equivalent ratio range of 0.91–0.71. The maximum temperature and emissivity decreased as the equivalent ratio decreased.
