  • Patent number: 12361189
    Abstract: A method, apparatus and device for predicting wall temperature deviation of a high-temperature heating surface tube panel of a boiler. The method comprises: acquiring factor data that affects wall temperature deviation of a high-temperature heating surface tube panel of a boiler; according to the factor data and a boiler structure, establishing a three-dimensional boiler simulation model in CFD software, and in the boiler simulation model, calculating the swirl intensity of a boiler furnace outlet by using a swirl momentum moment formula, and calculating a wall temperature deviation coefficient of the high-temperature heating surface tube panel of the boiler by using a wall temperature deviation coefficient calculation formula; and performing quadratic fitting processing on the swirl intensity and the wall temperature deviation coefficient, so as to obtain a prediction model.
