Abstract
(DE)
Verfahren zum Reinigen der Rohre eines Wärmetauschers (54) bei dem an das eine Ende eines Rohres (56) eine Strahldüse angesetzt und ein ein Strahlmittel enthaltender Luftstrom durch das Rohr geblasen wird, wobei eine drosselfreie Strahldüse (22) verwendet wird.
(EN)
The invention relates to a method for cleaning the pipes of a heat exchanger (54). According to said method, a jet nozzle is applied to one end of a pipe (56) and an air stream containing an abrasive is blown through the pipe. The invention is characterised in that a throttle-free jet nozzle (22) is used.
