| Abstract: | This article is mainly about the chemical cleaning of a Huaneng power plant with 1 000MW ultra supercritical unit at capital construction period.Cleaning systems and processes,main monitoring data,cleaning and passivation of the results are introduced.Some chemical cleaning experiences are proposed.Results showed that corrosion rate(0.48g/(m2·h)) and corrosion total quantity(4.80g/m2)is little than the required standards in DL /T794-2001.No residual oxides,no wash-off phenomenon and no copper phenomenon,uniform and dense film is on the metal surface.In conclusion,the result is beyond well,that provided some lessons and experience for the future in the country in the type of supercritical once-through boiler chemical cleaning. |
