| Abstract: | The cause of tube explosion of HG670/140-9 boiler water cooled wall is comprehensively analyzed in terms of water circulation, internal leakage of regular exhaust valve, uneven heating surface of water cooled wall and over-temperature due to tube blocking. The real cause of tube explosion is found, the preventive measures for tube explosion and requirement are also put forward. |
