摘要： 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).

摘要： Provided is an integrated coal gasification combined cycle equipped with: a gasifier that generates combustible gas from pulverized coal; a gas cooler; gas turbine equipment; an auxiliary fuel supply unit that supplies an auxiliary fuel to the gas turbine equipment; a heat recovery steam generator; steam turbine equipment; generators; and a circulation line unit that circulates cooling water. The heat recovery steam generator has a first medium-pressure coal economizer and a second medium-pressure coal economizer. When the combustible gas generated from the pulverized coal is burned, a serial heat exchange line is formed wherein cooling water passes through the first medium-pressure coal economizer, the second medium-pressure coal economizer, and the gas cooler. When the auxiliary fuel is burned, separate heat exchange lines are formed, wherein the cooling water separately passes through the first medium-pressure coal economizer and the second medium-pressure coal economizer.
