  • Patent number: 10527371
    Abstract: An anomaly monitoring device is installed in an integrated gasification combined cycle plant that experiences varying loads, and the device monitors a heat exchanger that performs heat exchange between a carbon-containing fuel and a heat exchange medium flowing through a heat transfer tube. For each load on the integrated gasification combined cycle plant, the anomaly monitoring device calculates the average value and the standard deviation of a state quantity of the heat exchanger, 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 of the heat transfer tube.
