Abstract
A method of in situ scale removal from a heat exchange body suspended in a wet cooling tower. At least one air blast is generated by a generator implementing controlled expansion via a nozzle of a mass of compressed gas in a nozzle towards a zone of the body. The generator is opened at a distance from the zone, and the method repeats the operation after moving the generator under the body outside the zone.
