Abstract: An anomaly monitoring device (10) is installed in an IGCC plant that experiences varying loads, and the device monitors a heat exchanger (20) that performs heat exchange between a carbon-containing fuel and a heat exchange medium flowing through a heat transfer tube (24). For each load on the IGCC plant, the anomaly monitoring device (10) calculates the average value and the standard deviation of a state quantity of the heat exchanger (20), calculates the Mahalanobis distance on the basis of the average value and the standard deviation, and from the calculated Mahalanobis distance determines the presence or absence of an anomaly of the heat transfer surface (28) of the heat transfer tube (24). Due to this configuration, the anomaly monitoring device (10) can more reliably detect an anomaly of the heat exchanger (20).
