The structure of the temperature measurement device and the principle of temperature measurement are introduced. Al I 690.6nm and Al I 708.5nm were chosen as the thermogram lines for temperature measurement based on the atomic spectroscopy database. The temperature of aluminum during combustion in pure oxygen was measured by photoelectric thermometer and compared with the measured temperature of thermocouple . The results show that the average relative error of temperature measured by the two methods is 1.5%, which proves the feasibility of temperature measurement based on double-line atomic emission spectroscopy.
