UNITED STATES l ATE lN'I v A HORACE M. JEROME, or Ann ARBOR, MICHIGAN, Assre-non TO U. s, rmissnn s'rEEL COMPANY, or 'YPSILANTI, MICHIGAN BOILER CONSTRUCTiON App1ication filed April 5, 1930. Serial No. 441,888.
This invention is-.comprehended by a new design of boiler which is shown and cursorily described in my copending application filed' on the same date. v
It has lon been known greater bene tfrom heat units was expectable if the products of combustion were compelled to follow a rather long. and sinuous passage before discharge into a stack. 1 A zig-zag flue travel has theoretical advantages, but has till now not proved feasible for use with products of combustion from an oil burner because of the profuse carbon deposition therealong until the temperature about the mouth of the burner has mounted to the stage of comcorrugated to increase the impingedmetal area and the straight interjacent portions of, the conduit are provided with tubular cen-1 tral partitions to prevent what is known as core flow or to compel travel of the heated gases in the annular passages between'the partitions and surrounding corrugated walls. It isto be realized that the scope of my invention comprehends many equivalent constructions; The showing of" the drawings and the particular description are merely specific exemplifications of a plurality of mechanical embodiments and arrangements.
Adverting to the drawings Figure 1 is a perspectlve View of the in-" terior construction of a boiler embodying the principles of my invention, the same being shown with the casing removed.
.Figure2 is a reariend view showing the sinuous and various zig-zag fluid conduit in dotted lines. a Figure 3 IS a vert1ca l cross section from front to rear in connection with that extraction of the discharge end of an oil burner. i i Y Figure l is a horizontal section on he; 4-4 of Figure 3. r
As revealed in Figure 1, the construction is composed entirely of steel and welded parts;
including a, front plate standard 1, a rear plate standard 2 and adjoining bottom 3. The front plate is provided near its top. with an-inlet 4 through whichanoil burning flame jet is tobe projected. The rearplate 5 is provided with three holes; 5 to facilitate cleaning or repair and the rear platealso has a lower stack outlet 6. The opposed-surfaces of the two plates are provided witha series of up right stiffening members 7 of bowed formation, likewise with a series of horizontal braces or corrugations 8 and near the top is reinforced with a pair of upwardly converging welded corrugations 9. The bottom 3 is similarly reinforced 'by a series, of crosswise extending arches 10. a j v 1; t
In communication with the inlet l is a combustion chamber 11 fashionedwitha corrugated cylindrical wall12.v The rear upper end of the combustion chamber communicates through a welded steel pipe 13 with the opening 5. Below the pipe 13 the combustion chamber 11 is providedwith an outlet for the production of combustion which. communicates with an elbow 14; as the first section of a sinuous doubly zig-zag flue conduit to be enveloped by a water reservoir. By doubly zigzag, I'refer to the formation clearly disclosed in Figurel wherein it maybe observed that the conduit has bothhorizontally and verti-. cally disposed U-shaped sections-welded end to end. Access'is hadto the elbow 14 through the middle of the rear openings'5. Thecome bnstion gases proceed-obliquely downwardly through the elbow 14 to enter a corrugated section 15 0f smaller diameter thanthe combustion chamber 12. The section 15 extends horizontallyalong one side of the-boiler, the front connects with another elbow 16, theme the flue passage continues through another horizontal section 17 then-cedirectly downwardly through a vertically disposed elbow 1 8 (to which access maybe had throughthe loweropening 5) which leads to another section 19 which is connected by means of a horilet, said passage being'fashioned with straight zontal elbow 20 with a last and rearwardly extending corrugated section 21, which discharges into the stack through the outlet 6.
All of the parts consecutively numbered from 12 to 21 are progressively welded together and some additionally to either of the end plates 1 or 2.
One of the features of my boiler construction consists of the provision within each of the sections 15, 17, 19 and 21 of concentrically located water tubes 22. The ends of which are open through the correspondingly located walls of the elbows 14, 16, 18 and to which 16 they are welded at 23, as may be clearly seen in Figure 4; The tubes 22 are therefore in connection at both ends 7 with the reservoir and while sealed against the flue passage section, in which they are located, will be envel- 2 0- oped by the gases of combustion. In addition to the added heat absorbing surfaces'which the tubes-22 provided, their presence hasthe additional advantage of preventing so-called core flow through the sections 15, 17, 19 and 26 21 and compelling the gases to creep along their inner corrugated annularsurfaces- A water-tight housing'is, of course, provided and may consist of a casing including side walls 2 1 anda bowed top 25. i
A gasifying chamber 26 of an oil burning unit is suitably mounted at the inlet 4 so that a spray of oil from a nozzle 27 may become ignited in the chamber 26 and project a resultingflame 28 into the combustion chamber 11 without, however, permitting the flame to impinge any surface of the combustion chamber because, as set forth in my earlier application herein identified, my developed type of oil burner so quickly attains perfect com- 40 bustion as not to require a preheated refractory lining and as to avoid a rigidly accumulated carbon deposit with its disadvantageous insulation consequence. v
The elbows 14, 16, 18 and 20 communicate 46 with short pipe lengths all designated by the numeral 29' and such pipe lengths have ends Welded around the openings 5 to afford access therethrough into the sectionsvof the conduit when alined registering handhole closures 50 (not shown) in the standards 1 and 2 or in the housing areopened.
It is to be understood thatthe' flame, whether from an oil burner,'as illustrated, or from a gas burner, may optionally be projected into the combustion chamber 11 at its other or rear end so that the products of combustion find entrance near where they are to find exit and thus would be compelled to follow a zig-zag' course at the outset also within the combustion chamber.
