ABSTRACT:
A method and apparatus of initiating and terminating the cleaning of a furnace wall to remove reflective ash which been deposited thereon, comprises a video or infrared monitor which monitors the light being reflected from the furnace wall or the ratio of the reflected to the incident light, the intensity of reflected light or ratio of the reflected to the incident light increasing as additional reflective ash is deposited. When the reflected light intensity reaches a selected value, cleaning is initiated and measurement of the reflected light is continued to monitor when the reflected light reaches a low substantially constant intensity. At that point, the cleaning operation is terminated since the constant reflected light intensity indicates a substantially clean condition.
