Abstract (en)
[origin: EP0570766A1] The invention relates to a method for cleaning a closed container (1), in particular a steam generator (1), by means of a cleaning solution (L) introduced into the container (1) or produced in it. In this case, at least a partial volume of the cleaning solution (L) firstly remains in the container (1) after a chemical and/or physical action on the container (1). It is provided that the container (1), in which the pressure is higher than the external pressure and the temperature corresponds to or overshoots the boiling temperature/point of the cleaning solution (L), is opened for a period of time for the purpose of boiling off. Thereafter, a residual volume (R), reduced by boiling off, of the cleaning solution (L) is removed from the container (1). <IMAGE>
