Evaluation of Non-thermal Plasma-assisted Combustion Temperature by Spectroscopic Measurement

In this study, non-thermal plasma-assisted combustion temperature was evaluated by spectroscopic measurement. First, temperature measurement by spectroscopy was compared with temperature measurement by use of a thermocouple. Temperature measurement by use of a thermocouple includes error due to thermal radiation, and this was corrected by calculation from material values of the combustion gas. In spectroscopic measurement, combustion temperature was calculated by Boltzmann plot method using CH radical emission. Next, it was shown that the temperatures measured by spectroscopy and by use of a thermocouple were in broad agreement. Finally, non-thermal plasma-assisted combustion temperature was measured by spectroscopy, and it was shown that the combustion was enhanced by non-thermal plasma.
