Abstract
A method for evaluating the clogging of the passages of a tube support plate of a tube heat exchanger, in which an eddy current probe is passed through a tube of the exchanger and a measurement signal is measured with the probe to evaluate the clogging at the downstream edge of a tube support plate. A lower (upper, respectively) edge signal corresponding to the probe passing the downstream (upstream, respectively) edge of the tube support plate is determined from the measurement signal. The impulse response of the probe is estimated. The lower edge signal is deconvolved () by the impulse response estimation. The clogging is evaluated () by analyzing () the lower edge signal thus deconvolved.
