| Abstract: | As the development of the digital imaging technology, it becomes possible to measure the temperature distribution in the furnace of the power plant, using the plane surface array CCD camera. In this paper, due to the radiative transfer equation, we analyze the reconstruction algorithm of reconstructing temperature field based on the flame radiative image. A synthesized non-linear mathematic model is developed to solve the controlling equations. This model combines genetic algorithm with Powell algorithm in optimization method, which adapts to the reconstruction of the temperature. To validate this model, an experimental system was set up in the boiler of a 300MWe power plant. The temperature distribution in the boiler is calculated according to this model. The experimental result indicates the convenience and accuracy of this algorithm. |
