SLAG-MONITORING DEVICE, REMAINING LIFE ASSESSMENT DEVICE, SLAG-MONITORING METHOD, AND REMAINING LIFE ASSESSMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2024/070772
Kind Code:
A1
Abstract:
A slag-monitoring device for monitoring the state of slag adhering to a furnace wall, the device comprising: a fin temperature data-acquiring unit that acquires time-series temperature data of a fin as measured by a fin temperature measurement device that is provided outside the furnace wall and that is for measuring the temperature of the fin; a fin temperature fluctuation range information-acquiring unit that acquires fin temperature fluctuation range information related to the fluctuation range of the temperature of the fin from the time-series temperature data of the fin; and a heat-resistant body thickness estimation unit that estimates, on the basis of first association information in which the thickness of a heat-resistant body that is attached to an inner surface of the furnace wall and and that is formed of a frame-retardant material and/or slag is associated with the fin temperature fluctuation range information, the thickness of the heat-resistant body corresponding to the fin temperature fluctuation range information.
