Abstract
The device comprises at least one assembly insertable in the enclosure through a hole situated in the vicinity of the tubular plate. Said assembly comprises a suction pipe having a curved part insertable in the casing through the hole and of a shape such that it terminates in the immediate vicinity of the plate, between the enclosure and the stack of tubes and a conduit placed inside the pipe, for connection to a cleaning liquid supply, ending in a nozzle for projecting water in a transverse direction to the pipe, along a grazing path with respect to the tubular plate and in the circumferential direction of the enclosure.
