Firstly, the flameemissivity were got by flame image detectors mounted at the different height of a CFB boiler, and then the bed height of the CFB boiler could be obtained by the BP neural network.
Based on the Wien's law temperature and emissivity of flame were obtained by processing the measured data with an optimization algorithm.
根据这一特点，从维恩公式出发，利用最优化方法处理测得的火焰辐射光谱信号，得到了火焰的温度和黑度。

Based on visual radiation image processing, a set of online combustion detection system in CFB boilers was designed in this paper, including the measurement of flame temperature and emissivity.
