Definitions

  • ABSTRACT A heat exchanger comprising a feed water chamber and a steam chamber extending to a considerable extent into said water chamber in spaced relationship to the housing wall of said water chamber so that the latter has a bell-shaped contour with the skirt thereof placed in spaced relationship over a portion of the steam chamber, said water chamber being divided by a partition into two sections, one of which communicates with one end of a plurality of pipes in said steam chamber while the other water chamber section com:
  • the present invention relates to a heat exchanger for heating up liquids, especially water, with steam or hot gases. More specifically, the present invention concerns a heat exchanger of the just mentioned type which comprises a nest of tubes anchored in at least one tube plate and leading thereinto by means of a plurality of individual tubes.
  • the heat exchanger furthermore comprises a longitudinally extending steam chamber mantle provided with steam inlet and outlet conduits which mantle is closed off at least on one side by a tube plate the tubes of which extend through the steam chamber confined by the steam mantle and communicate with a water chamber located on that side of the tube plate which faces away from the steam cham-
  • the heat exchangers comprise primarily a steam chamber 1 surrounded by a cylindrical mantle 2, and a water chamber 3 connected to the end of the steam chamber and confined by a mantle 4.
  • a tube plate 5 in which the nest of tubes comprising many tubes or ber and provided with water inlet and outlet conduits I while being surrounded by a water chamber mantle.
  • an object of the present invention to provide a heat exchanger which in spite of a large heat exchanging surface has a minimum length, and in which the heat stresses occuring in the pipe bottom are kept to a minimum.
  • FIG. 1 illustrates a longitudinal section through one end of a heretofore customary heat exchanger.
  • FIG. 2 shows a longitudinal section through one end of a heat exchanger according to the invention.
  • FIG. 3 illustrates a modified type of welding connection in connection with a heat exchanger according to the invention.
  • the heat exchanger according to the present invention is characterized primarily in that the water chamber mantle in the manner of a bell having an edge or skirt portion and in spaced relationship to the end of the steam chamber mantle extends over the said end while the water supplying and withdrawing conduits are connected to that portion of the water chamber mantle which extends over the steam chamber mantle end.
  • the steam chamber and water chamber have a substantially cylindrical cross section.
  • the central portion of the water chamber 3 is divided by a partition 9 into an inlet and an outlet part respectively communicating with a feed water inlet 7 and a feed water outlet 8.
  • the end face of the water chamber mantle 4 is formed by a bottom 10 which may be flat or arched and which has two inspection openings 11, 11' through which a portion of the water chamber 3 is accessible.
  • the inspection or checking openings 11 are adapted to be closed by a cover.
  • the steam chamber mantle 2 is provided with a steam inlet opening 12 for feeding the hot steam into the steam chamber and is furthermore provided with an outlet opening 13 for the discharge of the condensate.
  • the water chamber 3 has the same outer diameter as the steam chamber 1.
  • the water chamber mantle 4 is welded to that side of the tube plate 5 which faces the water chamber mantle. lnasmuch as the feed water enters at 7 in radial direction and the feed water is discharged at 8 in radial direction, it is necessary to provide corresponding pipe connections between the plate 5 and the bottom 10. In this way the water chamber 3 will have a considerable extension in longitudinal direction as a result of which the heat exchanger has a great length. Moreover, the mutual zones of influence ofthe welding seams 13 have to be taken into consideration by increasing the structural length.
  • the water chamber mantle 4 has an edge or skirt portion which extends in a bell-shaped manner over that end of the steam chamber 1 which is provided with the tube plate 5 and does so in spaced relationship to said end.
  • the tube plate 5 extends into the water chamber 3 to such an extent that the frictionless course of the water flow will not be disturbed by losses caused by a deviation of the flow.
  • That portion of the water chamber mantle 4 which extends over the steam chamber mantle 2 is expediently of a cylindrical shape. lts length is selected so that the radially entering feed water and the radially leaving feed water will find suffcient space while taking into consideration the mutual zones of influence of the welding seams. it is by this cylindrical portion that the total length of the heat exchanger according to the present invention becomes shorter than the total length of the heat exchangers according to heretofore customary designs.
  • a flange 14 The connection of the water chamber mantle 4 to the steam chamber mantle 2 is effected by a flange 14.
  • This flange may be a prefabricated forging or rolling piece of such a shape that a cylindrical member adapted to be welded into the steam chamber mantle 2 has that surface thereof which faces the water chamber mantle 4 designed in .the form of an annular cup formed by an outwardly extending flange and a peripheral flange 14 parallel to the mantle.
  • the free marginal area of the annular cup and the marginal area of the water chamber mantle 4 abut against each other and their edges are connected to each other by the welding seam 13.
  • the connecting flange 14 may be designed in conformity with FIG. 3 so as to form a ring.
  • the inner bore 15 of the ring is welded to the outer surface of the steam chamber mantle 2.
  • the outer marginal area of the annular connecting flange 14 is cranked in the direction toward the water mantle chamber 4 and is connected thereto by means of the welding seam 13.
  • All heretofore known types of heat exchangers may be equipped with an arrangement of the water chamber 3 according to the present invention.
  • all possible, especially square and rectangular cross sections are possible.
  • all heretofore customary heat exchangers may be equipped with the arrangement of the water chamber 3 according to the invention. More specifically, this is possible with U-shaped tubular heat exchangers on one side only of the steam chamber 1, and with straight nests of tubes on both sides of the steam chamber 1. Also the way in which the steam passes through the nest of tubes will not affect the possibility to provide the arrangement of the water chamber 3 according to the invention at one or both ends of the steam chamber.
  • a heat exchanger for heating liquids, especially water, by meansof hot media, particularly steam and hot gases which includes in eom bination: a steam chamber comprising a first mantle forming a tubular confining wall for said steam chamber and also comprising plate means integral with one end of said mantle and closing said one end, a bell-shaped water mantle having a bottom and a skirt integral with said bottom and surrounding a portion of said first mantle in spaced relationship thereto, said bell-shaped water mantle forming a unitary part fastened exclusively at said skirt also having an annular housing section comprising an annular flange integral with and extending outwardly from said first mantle and a peripheral flange parallelto said first mantle extending toward said skirt with its end integrally connected to the free end of said skirt, partition means interposed between and connected to said plate means and said bottom of said bell-shaped water chamberand dividing the latter into two separate sections respectively provided with a feed water inlet and a feed water outlet provided in said skirt
  • each said steam first mantle and said water mantle' has a substantially cylindrical outer cont0ur.
