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 heat exchanger is especially for cooling cracked gases with boiling water. It consists of pipes (1) that the gas to be cooled flows through and that are surrounded by a cooling jacket with a coolant flowing through it. The end of each pipe that faces the gas intake is surrounded by a sleeve. The coolant flows through the sleeve. The volume of coolant flowing through the sleeve is less than the heat supplied from the gas being cooled. (FIG. 1).

摘要： A plant for the pyrolysis of waste material containing hydrocarbons has a cooling stage. In this cooling stage, the hot pyrolysis gas coming from the pyrolysis reactor is cooled by direct heat exchange with low-boiling pyrolysis oil which is obtained in a further cooling stage by condensation of pyrolysis gas. For this purpose, a multiplicity of spray nozzles disposed in the form of a ring are provided in the heat exchange channel of the cooling stage, with a spray direction of the nozzles pointing substantially downwards. The end of the hot gas line which connects the cooling stage to the pyrolysis reactor is located above the spray nozzles. At the same time, feed lines for a protective, buffer or blanketing gas end in this region. In addition, an annular channel encloses the heat exchange channel and has orifices in the inner wall surface of the heat exchange channel, so that pyrolysis oil fed through the line cools and wets the wall of the heat exchange channel. This structure avoids the deposition of tar constituents from the pyrolysis gas on the wall of the heat exchange channel, while the hot pyrolysis gas is well cooled.

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 process of quenching an effluent containing materials having a tendency to coke is disclosed, the process being characterized by the quenching of the effluent in a quench zone wherein heat is transferred from the effluent through at least one heat exchange tube wall, and through a solid heat transfer medium surrounding the tube and in contact with the tube, to water, the temperature of the wall being maintained above the dew point of materials having a tendency to coke partly by the provision of the solid heat transfer medium which increases gradually in thickness from a point at or near the entry of the tube to a point at or near the exit of the tube.

摘要： A heat exchanger, reactor or like apparatus capable of carrying out heat exchange, material exchange or combinations thereof, comprises a cylindrical housing formed at one end with a cover and provided internally with a cylindrical partition carried by the cover and reaching toward but terminating short of the opposite end of the housing to subdivide the interior into an inner chamber or space and an outer annular chamber or space. A first fluid is fed to a helical-coil tube bundle in the outer space and then passes into a helical-coil tube bundle in the inner space before being discharged through a manifold and pipe in the cover disposed centrally. The inlet pipe or pipes are also carried by the cover outwardly of the central pipe. The conduits for the second fluid which open into the spaces and which pass around the heat exchanger pipes in these spaces are also carried by the cover and may extend coaxially with the first fluid conduits.
