Visualization method and system for combustion state of three-dimensional boiler

The invention discloses a three-dimensional boiler combustion state visualization method and system, and relates to the technical field of boiler combustion, and the method comprises the steps: obtaining the current historical information of a boiler, building a boiler performance degradation model according to the current historical information, and obtaining a boiler degradation rate according to the boiler performance degradation model; a flame image of the boiler is obtained, flame temperature and flame radiation energy are obtained according to the flame image, and the flame temperature is corrected based on the boiler recession rate; boiler parameters are obtained, flame radiation energy is corrected according to the boiler parameters, and a visual three-dimensional temperature field is established according to the corrected flame temperature and flame radiation energy. According to the method, the boiler recession model is established through the current, the recession rate is corrected according to th
