2 times water-cooled wall and convection tube explosion of 2 boiler into use within 2 years of some company in my city were introduced. The reason for this is mainly due to boiler water quality severely exceeded

improper use and poor management

and convection tube and water-wall tube wall scaling heavily

lead to convection tube and water wall tube of boiler overheating during use. Improvement measures were advanced to ensure the safe operation of the boiler.
