Method and device for detecting abnormal heat emission in an industrial process

摘要

The present disclosure relates to a method of detecting abnormal heat emission of an industrial process component in an industrial process to facilitate troubleshooting of the industrial process component. The method obtaining (So) a current thermal image of the industrial process component; obtaining (S 3 ) a reference thermal image of the industrial process component, the reference thermal image depicting the industrial process component in a normal condition; comparing (S 4 ) the current thermal image with the reference thermal image; and determining (S 5 ) that the industrial process component emits an abnormal amount of heat if a difference between the reference thermal image and the current thermal image is detected in the step of comparing (S 4 ) the current thermal image with the reference thermal image. A device carrying out the method is also presented herein.
