PURPOSE: To accurately monitor a combustion state, by three-dimensionally converting a combustion fire with respect to the image obtained by measuring the combustion flame using brightness or temp. information to display a combustion flame image.
CONSTITUTION: The analogue image data of the combustion flame, which is measured by a combustion flame measuring device and of which the image is sensed by an ITV camera 6 is converted to digital image data by an A/D converting device and the brightness at each coordinates point is stored in a digital image memory 9. An electronic calculator 11 calculates coordinates in order to three-dimensionally display the brightness or temp. of each coordinate point on a display device 14 as a height (calculates the temp. of each coordinates point when performs three-dimensional display using temp.) to display the same on the display device 14. Because the brightness or temp. distribution of the combustion flame 3 during the operation of a boiler is displayed on the display device 14 in a state easy to confirm visually, a combustion state can be judged accurately.
