Abstract

Es wird eine Vorrichtung zur Reinigung eines Wärmetauschers beschrieben. Gemäß einem Ausführungsbeispiel der Erfindung weist die Reinigungsvorrichtung ein Verdampfungsmodul auf, das in der Nähe des Wärmetauschers angeordnet ist, sodass es derselben Gasströmung ausgesetzt ist wie der Wärmetauscher. Die Reinigungsvorrichtung weist des Weiteren ein Zuleitung auf, die mit dem Verdampfungsmodul verbunden ist und über die eine Flüssigkeit in das Verdampfungsmodul geleitet werden kann. Das Verdampfungsmodul weist Auslassdüsen auf, die so angeordnet sind, das Dampf, der in dem Verdampfungsmodul durch Verdampfen der Flüssigkeit entsteht, durch die Auslassdüsen in Richtung des Wärmetauschers austreten kann.

A device for cleaning a heat exchanger will be described. According to an embodiment of the invention, the cleaning device has an evaporation module which is arranged in the vicinity of the heat exchanger, so that it is exposed to the same gas flow as the heat exchanger. The cleaning device further comprises a supply line, which is connected to the evaporation module and via which a liquid can be passed into the evaporation module. The evaporation module has outlet nozzles which are arranged so that the vapor, which is formed in the evaporation module by evaporation of the liquid, can exit through the outlet nozzles in the direction of the heat exchanger.
