Abstract (en)
[origin: WO2018234218A1] The invention relates to a method for cleaning surfaces in the internal volume of a heat exchanger (2), comprising at least the following steps: connecting the internal volume to be cleaned to a steam generator (4), generating a cleaning vapour (7) with a predetermined vapour pressure and temperature in the steam generator (4), applying the cleaning vapour (7) to the surfaces to be cleaned in the internal volume of the heat exchanger (2), maintaining the vapour pressure and the temperature inside the internal volume for the duration of a predetermined condensation time, generating a pressure drop (10) in the internal volume of the heat exchanger (2) to evaporate the portion (8) of the cleaning vapour (7) that has condensed during the condensation time and carrying away the cleaning vapour (7, 13) from the internal volume of the heat exchanger (2) by means of a drainage device (12).
