Title:
MONITORING DEVICE AND METHOD OF GAS TURBINE
Document Type and Number:
Japanese Patent JP2004339944
Kind Code:
A
Abstract:
To obtain a monitoring device for a gas turbine capable of detecting peeling-off of coating and time change in peeling area.
Combustion gas at the downstream of a high temperature region to be monitored is photographed with a combustion gas photographing device 15. A processing unit 21 detects a flying structure in the combustion gas on the basis of the photographed image of the combustion gas, and identifies a material in each element according to color of the flying structure. If the presence of the flying structure of a material identified with the processing unit 21 is continued for a predetermined period of time, warning for urging to confirm the damaged state of a high temperature region is issued to a warning device 22.
