Cleaning High Pressure Boiler Internal Surfaces
High pressure boilers need very clean internal surfaces. The pre-commissioning cleaning involves Alkali boil out to remove any oily materials, Acid Cleaning to clean up mill scales and Steam blowing to clean superheaters, reheater, and piping. Post-commissioning...Published on May 24, 2011 to Mechanical Engineering
