<p>The installation comprises a series of nozzles which are substantially tangentially directed and radially displaceably arranged before the front side of the storage mass (1) inside the heat exchanger, which nozzles let the supplied cleaning agent out of a cleaining agent source by directing the agent to the storage mass (1). The nozzles are provided on at least two nozzle heads (19, 17) arranged at a certain interval on a pipe (11, 13) extended substantially radially on one half of the front side of the storage mass (1), the pipe being sealed in the inner space of the heat exchanger and allowed to effect a reciprocating motion by means of a drive radially on the storage mass (1). By means of moving connections, the pipe (11, 13) is connected to at least one fixed outer conduit supplying the cleaning agent. The radially inner nozzle head (19) comprises, by reason of the reduced peripheral speed of the heat exchanger in this region, a number of nozzles smaller than that of the following nozzle head (17) located radially outwardly.</p> |
