摘要： A heat exchanger for cooling superheated steam with water, yielding saturated steam. The heat exchanger consists of U-shaped pipes (4) that the superheated steam flows through. The pipes are accommodated in a jacket (1) provided with intakes (10 & 11) and outlets (12 & 13) for the evaporating water. The pipes have their ends secured in a slab of tubes. The slab demarcates a chamber that is separated by a partition into an intake compartment (17) with an intake (14) and an outlet compartment (18) with an outlet (15). To improve the generic heat exchanger, part of the partition (16) has been removed and replaced with a rotating plate (19), the plate is attached to a rotating disk (21) that is perpendicular to the plate and has an opening (22) through it and a solid section on each side of the plate, the rotating disk faces a stationary disk (23) secured to the inner surface of the chamber (7) away from and parallel with the slab (5) and provided with openings (24) and solid sections that are similar to those in the rotating disk, and the side of the slab that faces away from the chamber rests on a thicker support (8).

摘要： A heat exchanger, especially for cooling cracked gas, with a nest of tubes secured between two tube plates (2) and with two terminal chambers (4) adjacent to the tube plates and tapering toward a connector (5). The intake-end chamber accommodates inserts. The inserts consist of rods bent into round or polygonal, concentrically positioned rings (7). The rings are positioned away from the tube plate in alignment with the intake-end connector in an area that essentially equals the connector's cross-section.

摘要： A nested-tube heat exchanger with tubes that are secured at each end in tube plates, for exchanging heat between materials at very different pressures. The first material, which flows through the tubes is very hot when it enters. One tube plate is thinner than the other and rests on a supporting plate. The supporting plate is fastened to a jacket that surrounds the nest of tubes. Each tube is surrounded by an annular gap where they extend through the supporting plate. To prevent particles in the water from depositing on the thinner tube plate, there are supporting fingers between the thinner tube plate and the supporting plate, the supporting plate is fastened to an inner supporting jacket and the thinner tube plate to an outer supporting jacket, both supporting jackets are attached to the jacket that surrounds the nest of tubes and demarcate an annular chamber, and the outer supporting jacket has a connection for supplying water and the inner supporting jacket has an access aperture at the side of the annular chamber that is remote from the water-supply connection.

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.

摘要： A tube-bundle heat exchanger for cooling a medium having a high inlet temperature. The heat exchanger has an inlet tube bottom and an outlet tube bottom, in which are fastened the ends of tubes which connect the bottoms and through which the medium of high inlet temperature flows. An intermediate tube bottom, having insert tubes arranged concentrically in the tubes, is located in the inlet chamber, with these insert tubes projecting out on both sides from the tubes and forming annular spaces therewith. Toward the inlet chamber, the annular spaces open into an intermediate chamber limited by the inlet tube bottom and the intermediate tube bottom; in the opposite direction, the annular spaces open into a deflecting or reversing chamber sealingly covering the insert tubes.
