A measurement method of the flame emissivity based on the blackbody furnace calibration of CCD （Charge Coupled Device） cameras and the color image processing techniques of computer was introduced. The experimental research on the flame emissivity in a 200 MW boiler furnace and a 300 MW boiler furnace was conducted respectively through the several CCD cameras installed at different height in furnace. The measurement results show： the flame emissivity increases with the increase of the unit load, the flame emissivity of the burner areas in furnace is the highest and the flame emissivity decrease with the increase of height of furnace above the burners area.展开更多
