Abstract��The proportion of water cooling wall tube explosion was relatively large in accidents of boiler�� and the cause was analyzed. The reasons mainly included the poor control of water treatment�� the improper selection of water treatment agents�� the unreasonable structure design and improper operating maintenance. The influence of water circulation�� subcooled boiling and scale formation on the temperature of boiler wall was illustrated based on fundamental theory of heat transfer. The metallographic analysis of swelling positions was conducted according to the metal material science. It was found that the boiler tube explosion was mainly caused by short-term overtemperature service. Several questions in actual operation of boiler�� which should be paid attention particularly�� were proposed. The suggestions in use and maintenance were also proposed to guarantee the safe operation of boiler.
