Abstract:
Provided is a damage estimation method that takes into account boiler-specific behaviors during earthquakes. A boiler damage estimation device (100) receives, from a cloud server (200), sensor data output after detecting the relative displacement of a furnace rear wall (22) constituting part of a furnace (2) of a boiler (1) and facing a cage portion (4) and a cage front wall (41) constituting part of the cage portion and facing the furnace rear wall, calculates time series changes in the relative displacement of the boiler on the basis of the sensor data, analyzes the progress of boiler damage and the amount of change in the shapes of the furnace rear wall and the cage portion, and outputs the analysis results.
