The invention provides an evaluation method for flame burning condition and stability, belonging to the technical field of energy and environment. According to the evaluation method, flame burning images are acquired, brightness feature matrixes Rij, Gij and Bij of three colors of red, green and blue are obtained; one color is selected as an evaluation color, and an evaluation standard optimum threshold Tk of an area, in which the flame is, is determined; each pixel in the brightness feature matrixes and the threshold Tk are compared so as to obtain the flame burning condition; and flame burning images of continuous working condition are acquired, an M value of each image is computed, and the flame burning condition is evaluated according to a mean value as shown in the description. The method provides quantification standards for the flame burning condition and stability and can give an accurate and objective evaluation, and can offer certain guidance for analysis and optimization of the flame burning process. The method is simple to operate, can obtain an accurate result, is fast, has high repeatability, and is less interfered.
