ABSTRACT:
A method for monitoring the corrosion of C-steel of a vessel, in particular of a steam generator, when the vessel is being cleaned using at least one chemical which releases a gas, in particular nitrogen, during the cleaning process. It is envisaged that the volumetric ratio or quantitative ratio between hydrogen and the gas released is determined in the gas/vapor mixture which forms during the cleaning process and this ratio is compared with a threshold value. The cleaning process is interrupted in the event the threshold value is exceeded.
