摘要：At least one of the heat exchange space (S1-S3) partitions (20) is in Z-sectionwhose raised center part (20a) extends over the support plates (19). The partition hastwo shorter parts (20b) bent to the center part and extending from the ends of thecenter part to the steam jacket (1) and there welded. The Z-section of the partitionrenders it flexible with the result that it moves yieldably off the pressure gradientbetween two heat exchange spaces and thus contacts the jacket casing to which ittransfers the pressure. The partition is double-walled to run parallel across the centerpart so the specifically thin walls are necessarily divided across an interval.
