| 摘 要： | 利用由ＣＣＤ线阵组成的微型光纤光谱仪研制了现场火焰光谱测量装置。通过测量３５０ＭＷ电站锅炉的煤粉火焰从 ５３３ｎｍ至１０５０ｎｍ波段的辐射光谱，发现煤粉火焰的辐射非常接近灰体辐射。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。

| Abstract: | With a compact CCD optical fiber spectroscopy a set-up for measuring the pulverized coal flame is developed. Experiments carried out in a 350 MW utility boiler with this set-up show that the radiation of pulverized coal flame from 533 urn to 1050 nm in wavelength is very closed to the radiation of gray body. Based on the Wien's law temperature and emissivity of flame were obtained by processing the measured data with an optimization algorithm. |
