A Spectrum Analysis Technique for the On-Line Monitoring and diagnosing of Pulverized Coal Flame in Utility Boilers

CAI Xiao shu, LOU Wu de (Dept. of Power Engrg., Shanghai Univ. of Science and Technology, Shanghai 200093, China)  
The radiation spectrum of coal combustion flame from 533nm to 1050nm in wavelength was measured in utility boiler with a compact optical fiber CCD spectrometer. Based on the Wien's law, temperature and emissivity of flame are obtained by analyzing the measured data. The experimental results also show some interesting features. First, the rediation property of the pulverized coal flame is nearly same as the property of gray body. Second, with the increase of the load of burner, the flame emissivity increases and temperature fluctuation decreases, respectively. Third, combustion in the center of boiler is much stable and emissivity is much larger than that of flame at the outlet of the burner. And last, temperature and emissivity of unburned pulverized coal are lower and stable. These properties of the radiation spectrum are very useful for monitoring and diagnosing of coal combustion flame. Figs6, tables 2 and refs 9.
