WATER CIRCULATING TUBE ATTACHMENT FOR HORIZONTAL BOILER FLUE Filed Oct. 17, 1949 IN VEN TOR.
H TTOR/VE Y Patented July 22, 1952 WATER CIRCULATING TUBE ATTACHMENT FOR HORIZONTAL BOILER FLUE Ralph E. .Grubbs, Glendale, Calif. Application October 17, 1949, Serial No. 121,801
This invention relates to boilers and has particular reference to devices within such boilers designed to increase circulation of water through the boilers thereby to substantially increase the efficiency thereof.
In boilers of the Scotch marine type it is customary to extend a relatively large furnace or flue horizontally through the boiler. This arrangement has-the disadvantage that the water above this flue becomes quickly heated,'while the water belowthe flue remains comparatively cold. In order to improve this condition it is common practice to extend an external conduit from the bottom of the boiler to the part of the boiler above this flue and while such water circulating conduit may improve conditions somewhat'it is objected to because of the extra expense and also because it interferes with other mechanism outside of the boiler. V.
It is in view of the foregoing the object-of the present invention to place within the-flue extending through the boiler a plurality of vertically disposed water circulating tubes. It is a further object to provide improved means for placing and securing such tubes within the flue of the boiler. 1
With these and other objects in view the invention resides in the combinations hereinafter described in detail and reference is invited to the accompanying drawings-in which preferred, forms of the invention are illustrated. V
In the drawing:
Fig. 1 is a side elevational view of 'afbo'iler withinwhich the device-of the 'inventionis in-.- stalled and parts of which have been broken away for the sake of clearness;
Fig. 2 is end view on a'larger scale taken.sub-' stantially on line 2 of Fig. 1 in the direction of the arrow; f
Fig. 3 is a similar view showing a somewhat modified form of the invention, and
Figs. 4 to 6' illustrate further modifications of the device. p v
Referring in the first instance to Fig. 1 the numeral I designates a boiler of the type above referred to, through which extends horizontally a relatively large flue 2, constituting the furnace or at least the element throughwhich the products of combustion are carried to heat the water therein.
As above stated, the water above this furnace or flue becomes heated very quickly, whereas the water below the flue remains relatively cold, for the reason that nothing is present to induce or 2 Claims. (01.122-145) 2 accelerate circulation from the bottom to the top of the boiler.
An eflicient and inexpensive way of producing better boiler circulation is to place a plurality of vertically disposed water conduits 4, 5, within the flue 2 to form direct passages from the lower to the upper portion of the boiler. It is readily seen that the combustion products passing through the flue will quickly heat these conduits and thereby cause the water torise rapidly from the lower to the upper portion of v the boiler.
In present day engineering Practice it is becoming more and more common to substitute modern methods of welding for the more antil5 quated and cumbersome methods of riveting or bolting parts together. 7 But because boilers are subject to inspection and approval by the authorities, the use of this more modern welding method still remains more or less restricted and it becomes necessary so to design, proportion and install such water circulating tubes that the installation thereof will meet with the approval of the authorities. It is a dominant feature of the present invention so to design, proportion and weld such water circulating tubes that they will 'pass inspection in various parts of the country.
Reference is now invited to Fig. 2 wherein the simplest form of my invention is illustrated.
The flue of the boiler is in this case designated by the numeral 2 and it is noticed that openings H and I2 are cut through the Wall of the flue in vertical alignment with each other.
V It is furthermore important to note that the upper opening I l is much smaller than the-bottom'opening l2.
This is done in order to make it possible to pass a circulating tube 4 upwardly into the flue through the opening l2. To the upper end of this tube is afllxed a flange Hi, the upper surface of which is curved to register with the inner surface of the flue wall to the end that, when the tube is completely inserted, this flange will come to rest against the inner wall of the 'flue. A similar flange I5 is secured to the lower within the flue. are welded in position, as indicated at ll, l8.

as found necessary and a second tube 16 is for this reason shown similarly mounted in position The rims of the flanges l4, l
In some sections of the country the authorities are more liberal, permitting the placing of larger openings in the flues of boilers for, installation and welding in position of morecomplex circulating tube assemblies. Sucha-ssembly'is, in Fig. 3, shown to include a pluralityof tubes, the upper ends of which are secured to a common flange 2 I', while the lower ends thereof are similarly se-.
cured to a flange 22. In this case, as in theabove described installation, the opening-Hat the bottom of the flue must be large enough to pass therethrough the flange 2!, the upper surface of whichis shaped to come torest against theinner surface of the flue whentheassembly is completely installed substantially as indicated in dotted outline at 24. The lower flange 22 must,
of course, be shaped'to come to rest against the outer surface of the flue when theassembly is completely seated, whereupon; the outer edges of t tw ang s ar W ldedinpesi i Q he flu In t e mo fi tion of Fi 4 ve ti a al n n ples 3 1 a We npo t on-w thi o ensstzai i f hee' ue vea h;n p l a be fi e w th a fla e en ag n thewal of t e :fiu h same anne that th tub se F f a ed. nd may be; imila ly weld d-i position- A p ece et e: 4 o thepro e lcngthisthe pushed hetweehg heitw pp1es1e nd welded in position therebeitween. this cas e, three ,sets
