ABSTRACT

In view of the water wall pipe burst of the heating industrial boiler, the research group carried out the water vapor sample analysis, the incrustation scale analysis of the typical rupture test pieces and the metallographic analysis during the operation. The researchers studied the cause of boiler pipe explosion from the chemical and metallographic aspects of materials, and found that most of the damage forms were brittle explosion, and the metal surface protective film was completely or mostly dissolved and damaged, resulting in a wide range of water wall pipe damage. The macroscopic inspection of the appearance of the water wall pipes in the furnace and the measurement of the thickness of the water wall pipes should be carried out during the shutdown and maintenance period, and the pipe sections that have not met the safety requirements should be cut off. During boiler shutdown and maintenance, other water wall pipes at the same position were checked with a water-cooled wall pipe tester. This provides effective treatment measures to solve the water wall pipe burst of the boiler.
