Method and device for judging ash and property attached to boiler facility and apparatus for judging and removing ash

摘要

To accurately grasp the property and falling possibility of ash adhering to a boiler facility without stopping the operation of a boiler.SOLUTION: A method for determining the property and falling of ash adhering to a boiler facility comprises: a step (S1) of acquiring time-series data of a heat absorbing amount of the boiler facility over a predetermined time; a step (S4) of performing Fourier transformation on the acquired time-series data of the heat absorbing amount; a step (5) of extracting a cycle having high-intensity peak in the time-series data subjected to the Fourier transformation; and a step (S8) of determining that the cycle having the peak is a cycle of ash falling off from the boiler facility.SELECTED DRAWING: Figure 4
