  • Method and apparatus for monitoring the formation of deposits in furnaces
    Patent number: 7607825
    Abstract: Method and apparatus for monitoring formation of deposits of solid particles from flue gas onto furnace walls formed of welded-together tubes through which cooling medium flows. For the entire surface of the walls, the exact surface temperature is detected with infrared cameras, offset by 90° relative to one another, via a thermal image obtained of a surface development of the furnace. This exact surface temperature is compared with the temperature of the cooling medium from measurement locations. Individual images from the cameras are composed to form an overall development of the inner surface of the furnace walls. The coordinates of the deposits on the walls are determined from the overall development, and the thickness of the deposits is determined from the temperature comparison.
