ECHANGEUR THERMIQUE POUR LE REFROIDISSEMENT DE GAZ CHAUDS, EN PARTICULIER DES GAZ CHAUDS ISSUS DE LA SYNTHESE DE L'AMMONIAC

摘要

A heat exchanger for the cooling of hot gases from the synthesis of ammonia. The heat exchanger has tubes which are bent into U-shape and are arranged within a shell. The tubes are inserted into a tube plate. An exit chamber and an entry chamber are arranged therein for the gases to be cooled adjacent the tube plate. Separating walls are arranged within the shell for the formation of closed preheating chambers and enclose the exit limbs of all tubes. The entry limbs extend within a separated middle space. A preheating chamber and the middle space are provided with separate connections for their own water passage.
