Abstract:
The present invention is an earthquake monitoring system for a boiler, the boiler comprising a furnace and a cage part that is disposed at the back of the furnace. The boiler has vibration detection sensors for detecting: the vibration of a furnace rear wall opposing the cage part of the boiler; and the vibration of a cage front wall opposing the furnace rear wall. The sensors are disposed on the furnace rear wall and on the cage front wall. The earthquake monitoring device analyzes the relative displacement amount in the three-dimensional direction between the furnace and the cage part on the basis of sensor data, and outputs the analysis results.
