Definitions

  • the present ⁇ invention relates to heat exchange apparatus, such, for example, as
  • a .further object is to provide an economizer which shall be compact in construction yet of high capacity and fleiciency in operation.
  • Still another object of the present invention is to provide apparatus of the above described type which 'not only may 'be easily and quickly installed, but which, should any of its parts prove defective or become dama. ed. may be repaired with a minimum loss o? time and at small expense.
  • Figure 1 is aside elevation with portions o the outer casing broken away to show the economizer construction in elevation;
  • Fig. 2 is a plan view, partly in section, on line 2-2 of Fig. 1;
  • Fig. 3 is a front elevation showing the stack and the economizer casing with the doors of the latter opened and a portion of one of the headers broken away; and spective view of a detached section of the economizer.
  • the'economizer is of the horizontal tube type and is mounted ina verticalsection vof the stack or iiue 5.
  • the economizer Fig. 4- is a perv ing spaced thereon disks or flanges 9.
  • headers 6 and 7 are of forged or cast steel and the tubes 8 are of steel, thus providing a structure of great stren thwhich can successfully withstand the hlgh pressures now commonly used.
  • the flanges 9 may be 50 mountedK upon the tubes in any suitable manner, as Iby shrinkin the flanges upon the tubes or expanding t e tubes within the .anges
  • the tubes are secured in the headers by being expanded therein,'suitable openings being formed in the headers to permit the passage of an expanding tool. As shown in Fig. 2, these openin s for the expanding tool are closed by p ugs sleeves or gaskets 12.
  • the economizer sections are arran ed one above the other in the flue 5 which orms a casing for the sections and serves to confine the hot gases passing from th furnace to the chimney.
  • the inlet and the outlet openings 14 and l5 of adjacentv headers are con y nected by means of the return bends 17.
  • the front header 6 has the middle partition 18 which divides the header into an inlet'and.80
  • the feed water enters the economizer through the yinlet-pipe 2O and leaves the economizerthrough the outlet pipe 21, the direction of iow of -the feed water being downwardly and the opposite of the flow of the gases which rise through the stack 5.
  • the economizer sections are supported upon the angle iron guides or supports 23, which are bolted at their ends to the vertical channel or U-sections 24, the headers 10 11 and copper 7 of each section resting with their lateral extremities on its angle iron supports.
  • a middle support for the same such as is shown in Figs. 1 and 2, in the form of a section of channel iron, the extremities of which rest upon the supports 23, and the tubes restin upon the top of the sides of the channel.
  • strap 26 with a depending shank and nut clamps the channel iron securely in position against the tubes.
  • the tubes of the sections are oii'set slightly toward one side, as shown in Fig. 4.
  • the offset of the tubes will be iirst to one side and then to the other, producing a staggered arrangement of the tubes which increases the eiiciency of the apparatus.
  • the outer walls 35 of the doors are extended beyond the margin of insulating material 36 and the inner wall 34, covering the joint between these parts and the casing thus preventing, or at least reducing, the leakage of air or gas at this point.
  • a soot cleaner is provided in the form of a steam pipe 38 which enters the economizer casing through the rear wall and which has a plurality of outlet openings 39.
  • This steam pipe is connected in a suitable manner for angular movement so that the ste'am may be directed against the different tubes to blow oil the accumulation of soot and dust.
  • each section is a complete unit, these sections may beassembled at any convenient,
  • the return bends and the inlet and outlet connections may be attached, thereby completing the assembly.
  • the sections are protected from corrosion both within and without by means of'a lead coating applied to each tube and header separately before assembling.
