Abstract: 

IN THIS PAPER, FAILURE MECHANISMS OF HEAT EXCHANGER (HEATER) TUBES OF AN ENERGY PRODUCTION UNIT WERE INVESTIGATED. RESULTS SHOWED THAT THE MAIN CAUSES FOR SUCH FAILURES ARE A COMBINATION OF HIGH BENDING STRESSES AND SPECIAL CORROSION AGENTS
BECAUSE OF HIGH VELOCITY OF VAPOR, TUBES WERE VIBRATED IN THE VAPOR INLET AREA OF THE HEATER AND FATIGUE WAS OCCURRED.
THE BEST METHODS TO PREVENT THIS KIND OF FAILURES ARE USING IMPINGEMENT PLATES (BUFFLES) AND CONTROLLING WATER CHEMISTRY.
