摘要： The heat exchanger is constructed with a single pressure vessel to contain the ducts for the hot gas flow and the heating surfaces for the secondary medium. The heat exchanger is provided with a central duct for the hot process gas and two parallel branch ducts through which sub-flows of the process gas pass. A throttle member is provided in at least one of the branch ducts in order to throttle the flow of hot gas therethrough. Additional hot gas can be bypassed from the duct section into the exhaust gas from the pressure vessel.

摘要： A heat exchanger, especially recuperator for high temperature reactors, comprising a prismatic extending jacket and a multiplicity of elongated hexagonal elements arranged within the jacket and essentially parallel to the primary direction or extent thereof. Each hexagonal element has a central tube and heat transfer surfaces arranged about each central tube and extending axially up to the outer contour or outline of the corresponding hexagonal element. Both ends of the heat transfer surfaces are connected to collectors seated upon the central tube. Each hexagonal element is connected by spacers with its neighboring elements and with analogous spacers spatially fixedly arranged at the region of the jacket laterally bounding the heat exchanger. The spacers have play so that the spacing between the elements and between the elements and the spatially fixedly arranged spacers can alter by the amount of such play. This play is dimensioned such that the sum of the play in any one respective direction over the cross-section of the heat exchanger still positively takes up without constraint the greatest differential expansion arising between the package of hexagonal elements and the spatially fixedly arranged spacers in such direction under extreme operating conditions.

摘要： A heat exchanger for cooling a hot, high pressure gas and utilizing the heat removed therefrom for generating hot water comprising a first and a second vertically elongated pressure containment vessels, the second vessel disposed coaxially within the first vessel so as to establish an annular space between the outer surface of the second vessel and the inner surface of the first vessel. A gas inlet pipe penetrates through the bottom of the first vessel opening into the second vessel at the bottom thereof and a gas outlet pipe penetrates through the top of the first vessel opening into the second vessel at top thereof, thereby providing a passageway for the hot gas to flow through the second vessel. Water is circulated through the annular space between the first and second vessels and heated therein as it absorbs heat lost by the hot gas passing through the second vessel.

摘要： A heat exchanger has at least two cylindrical shells defining annular chambers lying one within the other. One of the annular chambers receives a tube bundle consisting of straight tubes while the other annular chamber receives a tube bundle of coiled tubes. The heat exchanger is particularly suitable for the heating of feed water (traversing the tubes) with steam (traversing the annular chambers) in a power plant in which the heat exchanger is disposed directly beneath the turbine on the turbine mount.

摘要： Hot, soot-containing synthesis gas obtained by the incomplete combustion of carbonaceous fuels is cooled and heat abstracted therefrom in a waste-heat boiler containing one or more helically coiled tubes through which the hot gas is passed and one or more additional tubes through which steam is passed, said tubes being in external, heat-exchanging contact with a molten metal, metal alloy or metal salt coolant medium. The disclosed process and apparatus permit the generation of high pressure, superheated steam from synthesis gas while avoiding excessive pressure differences across the helically coiled gas tubes.

摘要： A heat exchanger particularly for cooling fresh cracked and/or synthesis gases produced through high pressure and high temperature having a casing with an inlet and outlet for gases. Straight casing pipes closed at their lower ends are located in the casing with centrally located immersion tubes of smaller diameter than the casing pipes for the supply of coolants in the casing pipes. A plurality of pipes forming rows of pipes spaced from one another and a plurality of rows of pipes spaced parallel next to each other are gathered into a nest of pipes. Longitudinal fins connect the casing pipes forming rows of pipes and the casing pipes standing opposite each other of adjacent rows of pipes. The casing pipes of the individual rows of pipes are of such length that their ends form parallel rows to each other aligned perpendicular to the longitudinal axis of the casing pipes. The rows going out from both outer rows toward the center of the nest of pipes gradually rise from pipe row to pipe row. The inlet and outlet side of the nest of pipes are covered with a conical gas inlet and gas outlet head and the length of the casing pipes is such, that a row of pipes in the area of said inlet and outlet heads increase gradually according to the conicity of the heads.

摘要： A heat exchanger arrangement wherein a plurality of cylindrical modular heat exchanger units are stacked upright in side-by-side relation within an enclosure and can be transferred into and out of the enclosure, one at a time, through a passage in the floor thereof. To transfer any given heat exchanger unit out of the enclosure, the unit is detached from its base, hoisted by an overhead travelling crane into a position overlying the floor passage and then lowered vertically into a basculating bridge underneath the floor. The bridge is then tilted into a horizontal attitude to discharge the unit. Transfer of a unit into the enclosure is accomplished by following the foregoing procedure in reverse order.

摘要： The heat exchanger comprises a bank of substantially straight and parallel tubes surrounded by a shell, the bank being constituted by juxtaposing adjacent layers of tubes, each layer extending between its own inlet and outlet manifolds. With such an arrangement, it is easy to provide a tube bank where the tubes lay in line with one another when the bank is viewed from above or from one side and this does not give optimum heat transfer between fluids within the tubes and fluids passed across the tubes in the tube bank. According to the present invention, the adjacent tubes in each layer are deflected by springing from near their ends so that alternate tubes in one layer are deflected in opposite ways and adjacent tubes in adjacent layers are deflected in the same way, to give better heat transfer efficiency.

摘要： 1,169,067. Tubular heat exchangers. E. I. DU PONT DE NEMOURS & CO. 20 July, 1967 [21 July, 1966], No. 33330/67. Heading F4S. A tubular heat exchanger comprises a cylindrical metallic casing 1, a bundle 60 of hollow tubular elements 61 of plastics material, the open end portions of which lie in a substantially coplanar arrangement and are sealed in fluidtight relationship with one another, and a header assembly co-operating with the open end portions of the tube bundle, comprising a first annular header member 30, formed of the same or similar material to that of the tubular elements, surrounding and secured to the bundle in sealing tight manner with such an annular clearance "A" remaining between said members 30 and the casing 1 that clearance will remain at the maximum operating temperature of the heat exchanger, a second metallic header member 20 abutting the first member 30 and held against axial movement in the casing by a shoulder 23, and a third member 40, also metallic, which abuts the opposite side of said first member and is also held against axial movement by an inwardly directed annular groove 11, a resilient sealing ring 51 forming an effective fluid tight seal between the first header member 30 and the casing member 1, a seal between the second member 20 and the casing being effected by either a ring (122, Fig. 3) or by a thread 29. The tubular elements 61 and the first member 30 are formed of an organic polymeric plastics composition, preferably a polyfluorinated plastic such as copolymer of tetrafluoroethylene and hexafluoropropylene. The tube bundle 60 is secured by helical spring-like elements 601 preferably of metallic composition, surrounding the tube bundle, and by a narrow elongated spacer strip 62 wound or interleaved between the tubular elements. In another embodiment (see Fig. 3, not shown) the spring 601 is replaced by a perforated sleeve (403) secured to the third header member, said sleeve supporting an annular baffle element 405 to control fluid flow in the casing member.
