AUTOMATIC BOILER TUBE LEAKAGE DIAGNOSIS SYSTEM

PROBLEM TO BE SOLVED: To provide an automatic boiler tube leakage diagnosis system that can accurately recognize the phenomenon of tube leakages in a boiler and determine whether continuous operation of the boiler can be conducted or the operation should be shut down immediately by identifying the degree thereof. SOLUTION: The automatic boiler tube leakage diagnosis system comprises a tube leakage recognition means for setting a boundary value recognizable as a tube leak for each of comprehensive phenomena occurring at boiler tube leakages, a tube leakage occurrence point display and alarm means for displaying and issuing an alarm for the spot recognized as being a boiler tube leakage by the tube leakage recognition means, a tube leak identification means for determining whether the level of the tube leak occurrence recognized by the tube leakage recognition means has exceeded the reference value set for each tube leakage phenomenon, and a shutdown urgency-level determination means for identifying whether the level of the phenomenon identified as a tube leakage by the tube leak identification means requires immediate shutdown or allowance of time for shutdown.
