  • the present invention relates to a heat-exchanging apparatus, and particularly to a heat exchanger consisting of a housing arcuately-shaped acurately-shaped shell sections positioned around and enclosing a central combustion chamber.
  • the present invention overcomes the disadvantages of the known prior art constructions by providing a heat exchanger assembly which is simple and economical in construction and without the necessity of having to provide additional bracing structures.
  • the heatexchanger housing is constructed having at least two arcuately shaped or U-shaped shell sections which arch outwardly and with at least one of the shell sections being provided with inwardly directed flanges which are welded or otherwise secured to a centrally positioned combustion chamber, and with the remaining arcuately shaped shell sections being welded or otherwise secured to the said one of the shell sections.
  • the arcuately shaped shell sections are positioned around a central combustion chamber and are welded together where there edges meet, and the sections having the inwardly directed flanges are welded to the combustion chamber where the inner edges of the flanges meet the chamber.
  • FIG. 1 illustrates in schematic perspective view one embodiment of the present invention and wherein two arcuately-shaped shell sections are employed
  • FIG. 2 is a further embodiment of a construction of a heat-exchanger .assembly according to the present invention shown in schematic perspective view and wherein four shell sections are employed, and
  • FIG. 3 is a top schematic view of a portion of a flange section of one shell section having apertures or perforations formed therein.
  • numeral l represents a top shell section and numeral 2 represents a lower shell section, both of which component parts have been formed in an arcuate or- U- shaped configuration by a rolling mill machine operation.
  • the lower shell section 2 is provided with inwardly directed flanges 4 which abut against and are welded to side walls 6 of a central combustion chamber 7.
  • the lower edges 3 of top or upper section l abut against the walls of lower shell 2 adjacent the flanges 4 and the two shells are welded together along these lines of abutment.
  • the flanges 4 are provided with openings or apertures 5.

  • the flanges l2 of the opposed sections 9 and 10 are of course provided with suitable apertures 5 to provide communication between the various cavities formed by the assembly of the shell sections.
  • the firing means for the combustion chamber has not been illustrated as such means may be of known construction and design.
  • FIGS. l and 2 heating gas ducts are indicated by numeral 13 but the connections between these ducts and the central combustion chamber 7 are not shown in the drawings inasmuch as such connections can be made in known manner.
  • the heating gas may be withdrawn from the combustion chamber 7 either from the rear or from the front with the result that it can then flow into the heating gas ducts from either the'rear or the front of these ducts.
  • the combustion gas outlet connections would then be arranged accordingly.
  • FIG. 2 illustrates a combustion chamber 7 conforming exactly to the combustion size of a combustion llame and the heating gases flow through the combustion chamber flues 7- to the front of the assembly where they then enter the heating gas ducts 13.
  • FIG. 2 illustrates a combustion chamber 7 conforming exactly to the combustion size of a combustion llame and the heating gases flow through the combustion chamber flues 7- to the front of the assembly where they then enter the heating gas ducts 13.
  • FIG. 2 illustrates a combustion chamber 7 conforming exactly to the combustion size of a combustion llame and the heating gases flow through the combustion chamber flues 7- to the front of the assembly where they then enter the heating gas ducts 13.
  • FIG. 2 illustrates a combustion chamber 7 conforming exactly to the combustion size of a combustion llame and the heating gases flow through the combustion chamber flues 7- to the front of the assembly where they then enter the heating gas ducts 13.
  • a heat exchanger assembly consisting of a housing and a combustion chamber and ducts provided in the housing for a fluid or gas medium which is to be heated, comprising a central combustion chamber, and at least two arcuately-shaped shell sections enclosing the said central combustion chamber and defining said ducts, one of the said shell sections having inwardly directed flanges secured to walls of the central combustion chamber, with edges of the remaining shell sections being secured to walls of the said one of the said shell sections, the said flanges having apertures to provide communication between said ducts.
  • a heat exchanger assembly according to claim l consisting of four sections enclosing the central combustion chamber, two opposed shell sections having inwardly directed flanges secured to walls of the combustion chamber, edges of the other two shell sections being secured to walls of the said two opposed shell sections to provide fluid or gas ducts completely enclosing the central combustion chamber.
