ABSTRACT:
The invention concerns a method for measuring the cleaning effectiveness of cleaning bodies (20) on heat exchangers having a bunch of tubes (16). Further, a plant is proposed in which the heat transfer from steam into cooling water through the walls of the condenser tubes is measured. The measurement is carried out with the aid of an inertialess temperature sensor (15) so that, by highly sensitive measuring of the temperature sequence of a certain control volume, the cleaning effect of the cleaning bodies can be derived.
