METHOD FOR CLEANING STEAM-GENERATOR HEATING-SURFACES

摘要

In a method for cleaning (particularly mechanically cleaning) the vapourizer and superheater heating-surfaces of steam-generators acted upon by flue-gases containing dust, the formation of adhering deposits upon the heating-surfaces is avoided. This is achieved, during the cleaning process, because the vapourizer-pressure and the superheatingtemperature are reduced briefly so that the surfacetemperatures of the heating-surfaces are below the softeningtemperature of the deposits adhering to them.
