Application December 15, 1934,. Serial No. #5711 12 5 Claims. (01. 137-78) This invention is an apparatus for feeding fuel oil to burners for boilers and similar installations.
One of the objects of the invention is to provide a feeding apparatus for fuel oil, so designed, constructed and arranged as to insure a regular, continuous and uniform flow of fuel oil to 'the burner atomizer. A further objectis to adequately regulate the feed of oil at the starting of the burner operation. A further object is to provide a multiple-stand-pipe oil reservoir connected with the feed line to the'burner, in such manner as to provide a gravity feed to the burner, said feed being controlled by the use of a motor-operated pumping system. Another object is to pro vide means for freeing any air whichmayhav been trapped in the oil, before it is delivered to the burner. r v
The invention willbe hereinafter fully set forth and particularly pointed out in the claims.
20 In the accompanying drawings:---
illustratinga fuel feeding apparatus constructed in accordance with the invention. Figure 2 is'a. side elevation with the multiple-stand-pipe shown elevation of the'multiple-stand-pipe and siphon breaker. Figure 4 is an enlarged detail sectional view of a portion of the multiple-stand-pipe memsiphon breaker.
Referring to the drawings, designates the boiler to be heated by the burner,
thesame being mounted upon legs I I, only one of vided with a hollow motor shaft, and through which the oil passes to feed the atomizer in the fire box in a manner well understood in the art. The pump I3 is connected with a tank l5 by means of a supply pipe 16 which is connected with .a strainer I1, the strainer in turn being connected with a lower chamber in the pump casing, by means of a conduit-J8. The parts thus far described, are all of standard construction in common use and are not herein claimed, except insofar as they are necessary to the operation of the invention here involved. Leading from the chamber in the bottom of the pump casing is a conduit Figure 1 is a top plan view, partly in section,
in'longitudinal section. 'Figure 3 is a: vertical.
ber. Figure 5 is a vertial sectional view of the l0 conventionally l9 which discharges int the multiple-stand-pipe member M.
'The multiple-stand-pipe member consists of a supporting casting 20 provided with a receiving chamber 2| formed by a transverse partition 22 which is provided with a central threadedopening. Above the chamber 2| the casting 20 is provided with a delivery chamber 23 and an overflow chamber 24. Extending upwardly from the partition 22 through the chambers 23 and 24, and
communicating with the chamber 2|, is a pipe or conduit 25. Extending upwardlyfrom the partition wall 26 which divides members 23 and 24, is
a larger conduit 21, the lower end'of which communicateswith the chamber 23, said conduit 21 being concentric with and enclosing the conduit 25. 'It will be noted that the conduit 21 extends above the end of the conduit a substantial distance as indicated at 28. 7 Leading from the top of the casting 20 is a larger conduit29 concentric with the conduits 25 and 21 and enclosing the same, said conduit 29 communicating with the overflow chamber 24. It
will be noted that the conduit 21 is provided with a. bleed opening controlled by a valve 30. The
The siphon breaker consists of a casing 40 having an inlet opening 4| communicating with the interior of the cap 36. The top: 42 of the casing 40 is removable and is provided with an air discharge conduit 43. Within said conduit is located a valve seat 44 which is complemental to a needle valve 45 provided with wings 46 which rest upon a float 41, the float is guided in its movement by a fixed stem 48.
In operation, when the current is turned on tothe burner motor in the usual manner, the pump motor'is energized and the magnetic valve is energized. As a result, oil will be drawn from the tank l5 through the pipe "5 and strainer 11 and then through the chamber beneath the pump casing, being then delivered to the receiving chamber 21. From the receiving chamber the oil travels upwardly through conduit 25' and overflows atthe upper end thereof within the. space 28 of the conduit 21. The oil will then flow downwardly into the delivery chamber 23 and from thence to the hollow shaft of the pump and then into the burner atomizer in a well known way. It will be noted that while the oil is being 5 pumped through the conduit 25, a larger amount of oil will overflow from said conduit than is necessary to support the burner flame. The surplus oil flows over the top of the conduit 21 and drops into the overflow chamber 24- and will then. be returned to the tank through conduit 34. The
object of the bleed hole controlled by the valve is to cause an early overflow of the oil as it passes down between the conduits-.25 eanda2l:,.soz:- that only a small quantity oipoiliatllowapressuregs.. 15 for a short period of time, will reach the burner after the burner motor is first started. t The. size. of the bleeder will be controlled by the valve 30.
Only a stoppage of conduitx34 COllIdFCBzllSQ'iOih' to flow into extension and into chamber...40..,
As the oil flows up into the extension 35;it will also eventuallyr. overflow into the. chamber: 40 so that the float 41 is lifted so as to seat the. valve 45 to prevent, escape of; the oil and t0= .conline it: in such manner. that the overflow: will .be 1 25;.returned to .the tank; As soon-.as.the..pressur.e.a
of the overflowis reduced, the float. :41; will drop and open the vent 43v so thatyair. ispermittedto; enter the upper part ..of the. stand-pipe; and; counteract any tendency of the downflowing.;oil;.-
in the conduit 29 to-createsiphon and robithe burner of fuel.
The advantagesof-theinvention will be readily understood by those skilled in the=art to. which. it belongs. For instance, it will be. particularly notedthat the device is so constructedandar-w ranged as to provide a continuous anduniform-:-
flow of fuel to the burner atomizer-at a gravity pressure and in such manner thatthe starting of:
the burner operation is greatly facilitated. An important advantage of the multiple-stand-pipe construction is that auniform gravity feediof the oilisprovided and at the sametime any tendency to produce a siphonic action toa suflicientextent to rob the burner is completely prevented m Having thus explained-the nature-of'the-in vention and described an operative manner of con--' structing and using the same, although'without attempting to set forth ,all'of the forms in which it may be made, or all of the forms. of. its-use," what is claimed .is:
