Abstract (en)

[origin: EP2312255A2] The method involves passing the cleaning fluid (16) through an opening with a supply line (2). The fluid is cooled by a cooling fluid (14) which flows around the supply line between the outside of the supply line and the inside of the supply line. An independent claim is also included for a device for removal of dirt from heating surfaces of a heat exchanger.
