Abstract The flame temperature was measured by the double line of atomic emission spectroscopy according to the spectra of K (766.5 and 769.9 nm) whose relative intensity was obtained by fiber spectrometer. The principles, methods and experiment system were described. The temperature measured by the double line of atomic emission spectroscopy was compared to the results measured by thermal couple under the condition of thermal equilibrium of blackbody furnace. The comparison indicated a good coherence between these two measurement methods. The method was demonstrated on coal powder and timber, and the temperature measured corresponded to reality.
