FURNACE Filed sept. '1, 1928 4 sheets-sheet 4 'Q Q Q Patented Aug. 4, 1931 'UNITED STAT-ES PATENT OFFICE 'EDGAR BOYDKAY, 0F WASHINGTON, DISTRICT OF COLUMBIA; FLORENCE MEANS KAY EXECUTRIX F SAII) EDGAR BOYD KAY, DECEASED FURN'ACE Application led` September This invention relates to improvements in furnaces, and more particularly to means whereby a furnace may be stoked, or the ashes withdrawn without affecting 'the draft of the furnace or admitting such an amount of cold air into the fire chamber as will-lower the temperature thereof. r
A11 object of this invention is to provide a simple, durable and inexpensive arrangement of parts that may be appliedto any of the usual types of furnaces previously con structed or be built into the furnace originally. i
A further object is to provide a structure wherein the stroking of the furnace may be effectively accomplished without the use of any of the complicated forms of shaker grate bars, consisting of rocking or tilting members subject to a, high rate of failure, are ex- 0 pensivefand diflicult to replace.
For purposesl of illustration apreferred form of the invention is shown it being understood that slight changes in form and minor details of construction may be resorted to without departing'from the spirit of the invention.
Similar numerals indicate corresponding parts in all the Afigures of the drawings in which:
3o Fig. 1 is a longitudinal vertical section Jthrough the furnace.
Fig. 2 is a similar enlarged view of a portion of the same. i
Fig. 3 is a front view of the parts shown as in Fig. 2. l
Fig. 4 isa horizontal section of these parts taken directly above the movable dead plate.
T'Vhile this invention may be a plied to any form of furnace, it is particu arly designed for use iny high temperature combustion units such as incinerators and the draw? ings show its' application to same.
By reference to the drawings by numerals, l indicates the frontwwall of the incinerator, 2 the main fuel feed and stoki-ng door frame and 3 the ash pit door frame.
The fire chamber is shown at 4, and 5 lindicates a portion of a grate made up'of any preferred form'of stationary grate bars, prol vided with draft passages.
1, 192s. serial 110.303534.
i The grate is slightly inclined downwardly toward the front of the furnace, and rests on across beam 6. 'Said beam 6 also supports the inner edge of a dead plate frame 7 to which it is secured in such a position as to ,bring the upper face of said frame flush with the upper face of the grate and form a contin'uation thereof.
The forward edge 8 of the dead plate frame is mounted in any preferred manner on the inner face of the main stoking door frame 2.
Then applying this invention to the usual form of furnace when forced draft is not to be used, no partition in the ash pit is required, butin the struct-ure shown as applied to a high ltemperature incinerator, a partition'9 is 'arranged across the ash pit, beneath the forward end of the grate and rear edge of the dead plateframe. v
The partition 9 is provided with an `opening 10 and closure doors 11, adapted when desired to entirely separate the ash pit into rear portionv 12, located beneath the grate 5 arlid the forward portion 13 beneath the dead p ate.
As stated above, partition 9 and associated parts are not necessary -when the usual induced draft is practiced, but uin the form of furnace shown, forced draft may be supplied tothe rear portion 12 of the ash pit 1n any preferred manner, such as through flues arranged in the side walls of the ash pit as shown at 14, provided with louvres 15 controlling the flow of'air into said chamber 12. Said flow of air may be supplied `from any source and be led under. control to 'chamber 12 in any Ipreferred manner.
The movable dead plate 16 in the form shown in the drawings is pivotally mounted at 17 and is adapted to snugly fit opening 18 in the frame 7. c)Said plate being provided on its under side Nvithdepending lu s 19 supporting a rod to which is secure the inner end of alink 20 extending out through the front of the incinerator, the outer end of link 20 is pivotally mounted on o erating arm 21, provided at its upper en with a socket 22, into which an operating lever 23 is ada ted to be inserted to operate the movable dea plate in an obvious manner.
To permit link 20 to operate, through a small opening in front of the incinerator, the lower end of operating armQl is connected at 24 to one end of a toggle link 25, the other end of said toggle link being mounted in a lug 26, projecting from the face of the furnace. Toggle link 25, provides a shiftable pivotal point for the operating arm 21, which permits the link 2O to traverse an opening in the front of the furnace practically the same size as the cross section of the link 20, as the operating arm 2l and link 20 are operatedto swing the dead plate 16 from open to closed position.
The main stoking or fuel door preferably operates on a slight incline, to provide as nearly as possible an air tight joint between the door and frame.
Arranged in the main door 28 is a stoke hole 29, through which the proper implement (not shown) may be introduced for the purpose of stoking the furnace. This consists of disturbing the material being burnt on the grates and causing the ashes and other noncombustible ash and residue, the liner particles passing down through the grates, and the coarser being dragged out on the dead plate.
The stoke hole is closed by a gravity door or cover 30, preferably pivotally mounted on pins 31 passing through lugs 32 and 33 mounted on the main door and Stoke hole cover respectively.
This cover as shown rests by gravity against the face of the main door and to increase the pressure and provide an air tight joint between said parts, the cover is weighted as shown at 34. A lug in which one end of an operating ring 36 is secured, provides means 45 f or opening and closing the stoke hole cover, which remains in either its open or closed position, due to the manner of mounting the same.
` In operation, air forced into the furnace, is heated during its passage through the tlues on its way to the rear of the ash pit, owing to the location of the air fiuesla at the sides of the ash pit, as shown.
To prevent. a blast of cold air entering beneath the grate when the ash pit doors are opened and permit cleaning out the forward portion of the ash pit without diminishing the temperature ot' same, the doors li covering opening l() in the partition 9 are provided to entirely segregate the rear portion of the ash pit fromthe forward portion.
To prevent an objectionable amountv ofI cold air reaching the fire chamber while stoking7 the stoke hole in the main door is provided, and to permit depositing time noncombustible material stoked from the lire gratos, into a chamber from which it may be removed,'with out diminishing the temperature either above or below the grates, the movable dead plate is provided..
In view of the above it will beobvious to one familiar with the operation of incinerators, that the material to be destroyed is deposited on the grate through an opening 50 directly above the fire grate. @n said grate' the garbage or other refuse Iis consumed. There. is however a part of said material which when consumed leaves a comparatively small quantity .of fine ash that readily passes down through the grate bars when the fire is stoked. On the other hand there is more or less incombustible substances ysuch as tin cans, rocks and the like that necessarily remain on the grateand must be stoked off and disposed of, and it is such material that may, by inserting the proper implement through the stoke hole, be stoked forward and pulled downwardly from the grate on to the movable dead plate, iompwhich it may be dropped into the front portion of the ash pit forwardly of partition 9. Such material may be removed from the ash pit without lowering the temperature above or below the grate. When the tiring up period is completed, and a reduction ofY temperaturein the furnace is not objectionable, doors l1 may be opened be incinerated is deposited on the grate,a
main stoking door normally closing said doorway, an ash pit arranged belowI the grate,a movable dead plate arranged between the grate and main stoking door, said grate beinginclined downwardly toward said dead plate, a second pit arranged below the dead plate, a partition segregating the ash pit from the second pit along the line where the front end of the grate meetsvthe dead plate, registering doorways for the ash pit and second pit arranged respectively in said parti` tion and said wall, doors normally closing said doorways, and means for operating the and the rear portion of the ash pit cleaned y lll@ dead plate to discharge materials from the iatter into the second pit.
