OIL-BURNING ATTACHMENT FOR FURNACE FRONTS.
Application led June 7,
The present invention relatesto oil burning attachments for furnace fronts.
It is frequently desirable to convert a coal burning furnace into an oil burning furnace,
Vand it is the object of the present invention to provide an attachment whereby this conversion may be brought about quickly and conveniently or the reverse accompli-shed, that is, the detachment or disassembling of the oil burning mechanism so that the furnace may be again adapted for the consumption of coal or other solid fuel. ,The invention. embodies a number of novel features including, among others, a novel furnace ring construction, novel means' for mounting the oil spray or nozzle for adjustment Vrelatively to the furnace ring and for removal, a novel arrangement of the valve controlling the flow of atmospheric air to the combustion space. Other features of novelty will be di-sclosed in the specification and drawings, and particularly pointed out in the appended claims. l Y
In the drawings Figure lis a front elevation of the oil burning attachment.
Figure 2 is a vertical axial section through the same and through the adjacent portion of the furnace to which it is attached.
Figure 8 is a horizontal axial section through the attachment and adjacent Vportion of the furnace, and
Figure 4L is a front elevation of the furnace attachment with the main portion or casing removed. j,
The face of the boiler. which may be of any well known type, either marine or stationary, is indicated at 10 and the wall of the fire box at 11. In converting a furnace from a coal to an oil burning furnace it is first necessary to reducecthe inlet opening of the fire box. Refractory brick work for this purpose is indicated at 12 and the refractory furnace ring at 13, the entire amount of air entering the furnace passing through the aperture in this ring so that the effective air inlet opening is greatly reduced as compared with the original fire box opening. The ring is made in four quarter sections, as shown in Figure 4, for convenience in manufacture and to increase the length of life of the ring in actual use. There is considerable expansion and contraction of the ring due to variations in temperature at the mouth of the lire box, and this expansion eachpairof registering slots extendstheV end of an S-shaped lug 15, the outer end-s of these lugsbeing secured by bolts to the false plate F. This false plate comprises two portions, the upper portion 16 and lthe lower portion 17, the abutting horizontally extending flanges of which are secured together by bolts 18. A central aperture in the false plate is indicated at 1.9Yand this aperture is co-axial with the opening in the furnace ring. It will be seen that the sections of the furnace ring are secured by the S-shaped lugs lto the false plate in suchv manner that the ring may be inserted and removed as a unit, and is held against inward displacement by this member.
Secured to the front of the fire box 11 is the casing 20 of generally cylindrical form.
which supports the oil spraying device and the valves controlling the flow of air tothe same. The furnace forced draft air duct (not illustrated) is adaptedto bring or lconvey air under pressure to the casing above the transverse partition 21 at its top, which partition is providedl with the vair Vport 22 controlled by slide valve 23. This valve may be movedhorizontally by means of an arm 24 mountedv upon an arbor 25 adapted vto be rotated by a crank arm and handle secured thereto and without the casing. Air passing under forced draft through port 22 finds its waythrough apertures 26 into the interior ofy the casing and thence through .the furnace ring into the fire box. A door 3() hinged at 31 to swing about a horizontal axis controls the port provided for the entrance of atmospheric air, this door heilig provided with latches L by means of which it may beV locked inclosed position. A sec- 33 to swing about a vertical axis. It is normally held in closed position by a latch 34 which engages a catch-35 secured to the casing. This door-32 is provided with a peephole or torch hole 36 normally closed by a shutter 37 and is'provided with an aperture 38 through which the nozzle supporting tube 39 extends.
Tube 39 is slidably supported in a bearfond door is indicated at 32 and is hinged at ing member 40 mounted on coaxial bearing axles 41, the out'erends of ivhich rest in suitable pocket or' notches 42 inv bearing blocks 43bolted to tlierasing. A post 44 projectsrear-Wardly from the door 32 and extends through an aperture in a lug 45 mounted on a collar Av4o securedto the rear end of the nozzle supporting tube 39. A set screw 47 extends through an aperture in lug 45 so that its inner end mayveiigage post 44 toI secure the nozzle supportingtube 39 in any :desired position of axial adjustment. The arrangement is such, however, thatv 'tube 89'may vbe tilted about its transverse anis of support so that the burner nozzle-may have thedesired relationship tothe furnace ring. This tilting is` accomplished by means ot an adjusting 'screw 5() which extends through threaded aperture infthe casing and lengages a lug 51 extending Vdownwardly itronrtlie bearing block 40. Lug'l 'and adjusting screw" are maintained in constantengagemen't because of the tendency oithe combustiontub'e' 39jto tilt in a` clockwise direction V(Fig. "2) ,f due to ythe" 'greater Weight Yot' its inner end, vto Whiclifthe slottedfburner cone is`"s`ecured. n
The application of the Iattachment to a *'urnaceinvolves, as previouslypointed out,
the insertion ot the` refractory" bricli' work, the furnace ring, and the attachment ot" the casing, allot lWhich may be donein' a relativelyl short time. The grate ofthe Afurnace may be' 'removed when the oil burning `at' Vtachment is installed,,oitlieV grate may b e covered With'jbriclr'lgnoivntto the'art.' -'l `o reconvertthQeZ-turnace orfthe use of vsolid jfuel it isonlyfnecessary y'to jremove Vtheoil burning equipment, furnace Vring-.and re- CII place the grate.'
` -One vslrille'dfin'furnace design Yand operation Will appreciate the advantages ot' the :invention disclosed and Willrealize that the ldesign yandv arrangement of' itsv'component elements maybe considerably changed with-V out departing from its spirit and scope.
