Patent DE-2023039-A1 (DE)
Title: Double jacketed steam heater for control- - led temperature water supply
Inventor: REMKE KARL-GUENTER
IPC: F24D17/00
Filed: 1970-05-12
Abstract: A heat exchanger for warming water up to a defined temperature without a controller, consists of an inner surface or tube containing the water, surrounded by an intermediate jacket of water, this in turn being surrounded by a steam jacket. Steam at any temp. or pressure is fed to the outer jacket and condensate is discharged through a trap into the middle jacket. This is at atmospheric pressure and therefore its temperature is automatically maintained at 100 degrees C. The temp. of the water being heated is thus effectively controlled and the device needs practically no maintenance.

Title: Vapour phase heating - low boiling dissociation products of heat transfer medium separated collected in cascade condensers
Inventor: LENK ERICH DR-ING
IPC: D02J13/00
Filed: 1972-03-16
Abstract: Condensers, with cooling ribs externally, and vertically stacked collecting trays internally are situated above the vapour space of the heating system in connection therwith, and vented above through a vavle. Because of the temp. gradient, non-condensable gases and vapours remain at the top, and condensable vapours collect in the stacked trays with low boiling liquids near the top. The lowermost tray should contain pure heat transfer medium. This is tested by a temperature probe. If the reading is lower than the medium boiling point at operating pressure, the condenser should be vented and cleared of dissociation products. Appts. can be used in conjunction with melt spinning plant etc.
