摘要：
THE COMBUSTION PRODUCTS IN A RECOVERY BOILER CAN BE BOTH CORROSIVE AND EROSIVE. AS LEAKS IN THE TUBES CAN CAUSE EXPLOSIONS, THE CONDITION OF THE BOILER SYSTEM MUST BE INSPECTED REGULARLY. SYSTEMATIC ULTRASONIC TESTING OF TUBE WALL THICKNESSES CAN GIVE INDICATIONS OF ABNORMAL CONDITIONS. BECAUSE AN UNINTERRUPTED FLOW OF FEED-WATER TO THE BOILER SYSTEM IS ESSENTIAL, THE FEED-WATER FLOW CONTROL SYSTEM MUST BE DESIGNED IN SUCH A WAY THAT IT CAN BE INSPECTED AND MAINTAINED.
