Definitions

  • each of these components is in the form of a column, or duct casing enclosing the apparatus constituting the heat exchanger, whose heat absorbing surface must be traversed by the hot fluid leaving the reactor and entering the component from a big header. It is then necessary to arrange ,a relatively large number of these component columns in a restricted space, permitting, however, their individual mounting and dismounting. Furthermore, provision must be made for variable expansions for the diiferent'parts of the installation, such as an economizer or vaporizer, or a superheater; or a combination of these units.
  • An object'of this invention is an arrangement for the mounting of these columnar componentsin a manner intended to solve the problems to be faced, andthe characteristic of which consists in that the elements or columnar components are suspended and the interchangeable supporting beams aresolidly fixed to the big gas headers which offer great rigidity, while the other pipe lines have a small diameter and are very elastic.
  • the, components which are all identical with respect to the duct-casings and tubular connections thereto, are suspended in double rows, perpendicular to the general direction of thejheader or headers for the supply of thehot fluid provided at the upper part of the installation.
  • rows of columnar components rests on a median beam extending transversely to the header, and actingalso to the header itself of whichv it is an interdependent part.
  • the extremities of these beams, for their part, rest on the walls of theinstalllation by means of rollers or similar arrangementspermitting expansions,,especially in a direction. parallel to the exchanger or exchangers.
  • Sub-headers transversely inserted in the main header or headers, .feed the columnar components of each double row, and these columns themselves are suspendedby flanges on the transverse cantilevers of'the supporting beam. Only at its lower part'the main return header is ela'stically supported by socketspermitting theexpansions of the columns to run in'vertical direction.
  • Figure 1 shows schematically a unitary component according to the previous patents of the applicant and con1- prising the necessary economizer, vaporizer and superheater surfaces for obtaining two steam stages.
  • Figure 2 shows schematically a sub-division of such a component into five separate elements each containing only one or two of the economizer, vaporizer and superheater apparatus necessary for the same production of steam as the element shown in Figure 1.
  • Figure 3 shows in perspective a part of an assembled installation embodying a plurality of columnar components of the type illustrated in Figure l;
  • FIG. 4 shows in a vertical end-view two double rows of components.
  • Figure 5 shows in perspective a grouping of columnar components of the types shown on Figure 2 in a thermal installation comprising a large number of elements.
  • FIG. 1 There is shown in Figure 1 at the inside of the column or ductcasing 10 a series of heat absorbing elements of the type described in previous patents by the applicant.
  • the duct 10 traversed by the hot fluid entering at the upper part as indicated by arrow A is discharged at the lower end as indicated by arrow B.
  • the heat absorbing elements comprise two steam producing stages; one at low pressure with economizer 12, evaporator 14, superheater 16 and, the other at high pressure, with economizer 13, evaporator 15, and superheater 17.
  • the feedwater is introduced at the lower part at 18, 19 and the steam outlets are at the upper part at 20, 21.
  • each. of these double 1 As can be seen in Figure 3, the components as assembled have the form of tubular column-like casings to the, upper part of which the hot fluid is fed to pass downwardly through the columns and discharged at their lower ends.
  • the numeral 22 designates the main header which conducts the hot fluid coming from the reactor.
  • sub-headers 24 are transversely fastened and arranged to f eed-the rows of columnar components. These are arranged in double,
  • each double-row is supported by a median, transverse beam 26, which passes through the center of the double-row and which lies at 27 under the header columnar components 10 are suspended by means of studs or flanges 36 provided at the-top and on'both sides of component 10.
  • studs or flanges 36 provided at the-top and on'both sides of component 10.
  • aasaaeo is connected by means of a nipple 40 to a sub-header 24; this nipple 40 permits insertion of a valve or shutoff device.
  • the suspensionof componentsltl by means of flanges 36 between two cantilevers is accomplished in such mannerxthat it is possible to shift a, coiumnar component 19. in two perpendicular directions to make it possible during erection to bring into position the upper opening 41 of each components 10 with nipple 40.
  • the components 10 are connected by nipples 42 tothe sub-header 44 which is fastened to the hot fluid return-header 46,.
  • This header 46 is supported by means of cradles 48 which are mounted elastically, enabling them, to follow the expansions of the header in such manner as to allow expansions in vertical directions of all the components 10.
  • These cradles 48 can slide in the direction of the axis of the header.
  • each double row of elements has only one returnheader 46 (on account of the decrease in temperature of the fluid leaving the elements) which ensures at the lower part a connection ensuring the equahdistance of the elements located vis-a-vis in a double row.
  • the assembly takes expansions of the header 22 in the direction of its axis into account due to the capacity of beams 26 to slide on the ledges 3t), 32 of walls 33.
  • the expansion in vertical direction is absorbed by the elasticity of cradles 48 under header 46; columnar components 10 furthermore being simply suspended by means of flanges 36 on cantilevers 35.
  • each columnar component 10 into the place which it has to occupy ll]: the double row and, eventually, to remove it from t ere.
  • water intakes 18, 19 are foreseen at the lower part, two for each element, and steam outlets 20, 21 at the upper part, likewise in the number of two, and connected to main steam outlet headers 49.
  • steam outlets 20, 21 at the upper part, likewise in the number of two, and connected to main steam outlet headers 49.
  • main steam outlet headers 49 instead of, or in addition to one single inlet header 22, it would be possible to foresee two headers at the ends of beams 26 so as to adjust the shifting due to expansions. It would even be possible to foresee more than one outlet header 49.
  • the heat exchange elements are distributed among five separate units 50-54 in which are arranged respectively low pressure economizer 12b in unit 50, low pressure evaporator 140 in unit 51, low pressure superheater 16d and high pressure economizer 132 in unit 52, the high pressure evaporator 15] in unit 51 and finally the high pressure superheater 17g in unit 54.
  • Elements 50 to 54 are traversed in the direction of the arrows by the hot fluid entering a A and leaving at B.
  • pipe line on which supplies the hot fluid, and to which they are connected at the upper part. Fluid from their lower parts is collected in pipe line 62 which leads to pipe line 64 which feeds in parallel" all components 53 and so on .up to the hseating fluid discharge which is efiected through pipe inc 6.
  • the advantage of this arrangement consists in that, as has been stated, the heat absorbing elements within each component 54, etc. of each group only contain identical apparatus, having to function between narrower temperature limits than those of the arrangement shown on Fig ures, l and 3.
  • the expansion of the assembled apparatus ofthe same panel of components 54 for instance is then nearly the same and especially far more reduced in all directions of the panel, i.e. in the vertical direction as well as in the horizontal direction, It then becomes possible to assemble the panel in a safer manner, for instance, as shown on Figure 5, on a common beam 26A with support rollers 34A, permitting the expansion to run out.
