In this paper, we take flame optical radiation signal in low-frequency on a gas combustion test-bed as research objects, multi-fractal spectrum can analyze the micro structures and characteristic of flame optical radiation time series is corroborated through computing. We research the trend of the sharps and key parameters of the multi-fractal spectrum under different scales. Result shows that as one of the most important parameters of multi-fractal spectrum, the width of the multi-fractal spectrum has the significant correlation with variance, which reflects the status of the combustion stability, and the accuracy of the combustion stability judgement is increased further through multi-scale and multi-fractal analysis. As a developmental assisted analysis method, the multi-scale and multi-fractal analysis method can effectively reveal the dynamic process of the flame radiation, which provides to the operation staff with multi-angle supplementary method in judging the combustion stability.
