    Abstract: PROBLEM TO BE SOLVED: To provide a method of monitoring the on-line deterioration of boiler tubes 15a, 15b in a large-scale combustion device, particularly, in a waste incinerating plant.
    SOLUTION: The deterioration, particularly, corrosion of the tube, or the accumulation of deposits are determined, more or less, in a continuously way in the state of operating the combustion device. The method is, therefore, not limited to optical inspection during a resting time. The speed of the deterioration or its accumulation relates to an operation mode for facilities. An adequate deterioration sensor 4 is arranged outside a flue gas region 14 where the boiler tube is exposed to harmful flue gas from a combustion process for receiving ultrasonic signals from a space or a capacity in the flue gas region 14. A test/tube 40 is provided exclusively for monitoring the progress of the deterioration. It is incorporated in the flue gas region 14 where it is particularly influenced by corrosion.
