DEVICE AND METHOD FOR OBSERVING ABNORMALITIES IN CIRCULATING FLUIDIZED BED BOILER

摘要

An abnormality observation device (1) of a circulating fluidized bed boiler (2) comprises an operation data acquisition part (21) for acquiring operation data composed of sensor data (x1-xk) of the circulating fluidized bed boiler (2), an abnormality determination part (34) for determining whether or not there are operation abnormalities in the circulating fluidized bed boiler (2) on the basis of the Mahalanobis distance (D2) of the operation data, an image data acquisition part (22) for acquiring image data of predetermined image regions (16a-16e) of the circulating fluidized bed boiler (2), and an operation data synchronizing recorder (36) for synchronizing and storing the sensor data (x1-xk) and the image data of the image regions associated with the sensor data (x1-xk) when the abnormality determination part (34) determines there to be an operation abnormality.
