Abstract: The invention relates to a system and a method for diagnosing and preventing the high-temperature corrosion state of boiler water wall. It comprises a plurality of temperature sensors, which collect the temperature of the water wall through a multi-channel A/D conversion acquisition module; The coal quality sampling module of the coal in the furnace sends the coal quality information to the coal quality analysis module, and the coal quality analysis module carries out industrial analysis; The pulverized coal fineness sampling module sends the collected pulverized coal fineness information to the fineness analysis module; The smoke sampling module sends the collected smoke information to the component analysis module; The data layer module performs filtering processing according to the obtained temperature information, coal quality information, fineness information and smoke composition information, and removes pathological data; The characteristic layer data processing module extracts the characteristic quantity of the data processed by the data layer module; The decision-making layer module comprehensively analyzes and judges the data extracted by the characteristic layer data processing module, draws a reasonable and accurate conclusion, outputs it and participates in the operation adjustment.
