Recently, the diversification of fuels in the field of ship energy has been recognized as an essential market change in emission reduction regulations. In particular, the fuel blending of LNG ships is the most common technology that can reduce carbon dioxide emissions without replacing existing diesel engines. Precise measurement of the flame temperature is essential for connecting an existing diesel engine with a new fuel composition. This study verified the possibility of measuring flame temperature by using thermal imaging cameras with the advantages of non-contact measurement, wide-area measurement, and real-time measurement. Thin filament pyrometry (TFP) technology is applied according to the thermal imaging camera characteristics, and errors between measurement areas are minimized using the inverse square law. Bunsen premixed flames (equivalence ratios: 0.7, 1.0, and 1.3) and a counter-diffusion flame were adopted to measure the flame temperature by using 1D numerical calculations. The measurement distances between the flame and the camera were 40, 45, and 50 cm. The obtained results showed a maximum accuracy of 96% for the Bunsen premixed flame compared to the calculation. Based on these data, a verification test was conducted on the counter-diffusion flame, and an error rate of 1.3% was obtained using the method proposed in this study.
