BURNING CHAMBER. FUR. INCINERATORS.

Applicatiiin filed August 1, 1924, Seria1 No. 729,652.

ing at Dallas, in the county of Dallas and State otTexas, have invented certain new and useful Improvements in Burning Chain bers for Incinerators, of which the following is a specification.

. This invention relates to new. and. useful improvements in burning chambers for incinerators.

Theobject ofthe invention is to provide means in a burning chamber for suspending large and slow burning matter in the chamber above the fire grates, whereby said matter is dried out and burned by fires both above and below it and. cremated in. a highly efficient and improved manner.

A further object is to providesuch suspension means between battle walls, whereby a greater circulation and more intense incineration may be carried out.

Another object isto provide such suspension. means in combination with .pre-drying and. liquid collecting means in thechamber, so that matter delivered to the suspension grates will be more orless free 'fromliquids and. the latter ,prevented to a. large extent, from passing to the tire grates and. ash pits.

A still further object is to provide suspension grates composed of water conductors, whereby said grates are prevented from burning. out and whereby hot water and steam maybe obtainedfor various purposes.

Another object is to provide a burning chamber having a battle Wall therein with a flame passage therethrough and suspension grates on each side of. said wall, whereby the flames pass through said-passage above and below the. grates. y

A further objectis to provide doors whereby access through the front .wall of the chamber may behad-to the nppersurface of the suspension grates as well as to the fire grates below, so that both may be efliciently stoked and non-combustible matter easily removed from either.

. A; construction designed. to carry out the invention will. be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which anexampleot the. inventio-nis shown, and wherein:

Fig. 6is a cross.sectional view taken on the line 66.of Fig. 5, and- 7 Fig.7 is a detailof one of the roof blocks...

In the drawings the numeral. 10 designates. a base upon which a front wallall, an end. wall 12,a rear wall 13wand anend. 14 are erected: These walls and the base. are suite ably constructed in accordancewith incinerator engineering. The rectangular struc tureformed by theseparts is comparatively shallow from front to rear in. proportion -to itslength between the end walls. This is an important featureas it permits all parts of the interior to be reached through open? ings in the front wall, with. a short handle rake and thus cuts down thestoking room usually required in frontnof the incinerator.

A floor .15 is supported at the upper-ends of the wall and is composed of -a concrete mixture reinforced by I-beams 16 extending .at right. angles to each, other and having their ends supported inthe walls. The incinerator is charged from the floou. A ver tical division wall 17 adjacent thewall 14 divides the interior of the incinerator, the greater portion, about fountifths more or less, lyingto the right (Figs Band 4) and constituting a main or burning chamber. I provide.- a floating or. detached roof or arch for, this chamber composed of tire resisting blocks or tile18, suspended from clamps 19 (Fig. 7) supported by eye bolts 2Q depe-nd- -g fnolnhanser 2. clampe t the ams 16. These blocks may assume a desired o m and i efit ina e he re no t ed to the walls 1 of the furnace,- thus, allowing r xp nsi rand e t ac on n P r-mi ting ready removal and. replacing.

Over the rear portion of the chambenthe roof is horizont l. ut i inclined down- -wardly over the front portion thereof. By

using square blocks uniformity is had, and rectangular charging hoppers 22 may be used. The hoppers have their upper ends flanged and countersunk in the floor 15. Each hopper has a vertical collar 23 secured to its lower end and surrounded by the blocks 18 of the roof. The details of the hopper form the subject matter of a ctr pending application filed August 1, 1924:, Ser. No. 729,650. In each collar is hinged a cover composed of a tire resisting tile 24 secured in a back 25. interior flange 26 at the bottom of the col lar. From. the front end of each cover a flexible connection 26 extends upward and passes behind a pulley 27 on the rear wall of the building. By this means the cover may be swung upward in a convenient manner.

The hoppers have their greatest length directed forwardly as is shown in Fig. 2 and are located near the rear wall 13. Within the burning chamber and under the hoppers is an evaporating and drying table 28 inclined downwardly from the rear wall and having its front end supported abovethe base 10 on a vertical wall 29. The table is suitably formed of tire resisting material and may be made in sections or block so as to be replaced. This elevated table has a longitudinal sump or trough 30 along its front edge for catching and retaining the liquids, whereby the latter areevaporated and prevented from flowing down intothe ash pits. This table is arched over a fine or tunnel 32 extending parallel to the rear wall 13 and behind the wall 29. The bottom of the tunnel is formed by'the base 10. As will be hereinafter explained the hot gases and air currents escaping from the burning chamber pass through said tunnel, thus heating the table from the underside.

The table 28 and tunnel 32 constitute dry-- ing or pro-heating means and are specifically covered in my oo-pending application filed August 1, 1924, Ser. No. 729,653. As will be obvious from the following description, it will be seen that any type of table or equivalent means heated in any suitable manner could be used.

The burning chamber is divided by transverse vertical battle walls 33 extending from the base 10 to the roof andfrom the front wall 11 to thewall 29, and the front edge of the table. Between the walls 33 and on each side thereof. are fire grates 34 of any suitable type. These grates are supported by the walls 11, 12, 17, 29 and33above the base 10 and about midway the height of the front ofthe table 28. Ash'pits 35 are formed below the lire grates and access is had thereto through doors 36 in the front wall 11.

Above the grates 3a are suspension grates The tile rests upon an drawn off by opening the valve.

37 located in a plane substantially flush to the front edge of the table, but subject to variation. .1 have shown three units (Fig. 3) separated by the baflie walls 33. Each unit s composed of a front header 38 and a rear header 39 parallel to the front wall. 11 and the table 28, respectively the heads are connected by spaced tubes 40 forming the grate bars. A water supply pipe ll eX- tends into the wall 12 and is connected to the adjacent rear header 39. The front header of the first grate is connected to the front header 38 of the second grateby a coupling 42, while the rear header 39 of the second grate is connected to the rear header of the third grate by a coupling 43. A discharge pipe 44 leads from the end of the header 38 of the third grate adjacent the wall 17. It will be apparent that water entering the first grate (Fig. 3) at the right will flow through the various units and es:

cape through the pipe 44 either as hot wa ter or steam. I

The pipe 44 is connected with a vertical pipe 45 which enters a manifold 46 disposed alongthe base 10. The right hand end.

(Figs. 3 and 6) of the' manifold is closed by a cap 4-7, while a valve 48 is connected to the other end and has a nipple 49. Risers 50 extend from the manifold and are connected to nozzles 51 extending through the front wall 11 into the ash pits 35 below the grates 34. Steam may thus be supplied in jets from the nozzles. Hot water may be Doors 52 in the front walls give access to the spaces between the grates; while other doors 53 give access to the grates 37. Flared liners 54. in the wall 11 at each of these doors make for free stoking and access to any part of the burning chamber. 7

Each battle wall has a'central opening-55 extending from a point between the grates 31 and 37 to the roof of the burning cham her. A similar but larger opening 56 is provided in the wall 17 forthe escape of the products. It will be seen that the air currents and flames will pass through the openings 55 in the battle walls above the grates 3el'and above and below the grates 37, thus thoroughly igniting and burning matter deposited upon said grates. The flames and currents will also whip around the rear ends of the baflie walls and pass over the front of the table 28. These flames, currents and cases will be drawn toward the opening 56 and at this point the fire will be most intense, providing a cut-off fire through which all products must pass.

.The essential feature of the invention being the suspension grates and the baffle walls, it will be seen that the garbage and trash might be delivered directly to said grates. The openings in the walls permit a fre passage and circulation of the flames and allow them to pass above and below the matter suspended on said grates. The shallow burning chamber and the flared openings permit the grates to be efficiently stoked and also afford a ready means of removing tin cans and other non-combustible matter.

So far as this invention is concerned the outlet 56 may connect with a passage for conducting the products to a smoke stack. In the drawings I have shown a superheating chamber 57 and a combustion chamber 58 formed between the division wall 17 and the end wall I l. The chamber 57 is connected with the opening 56, while the chamber 58 is connected with the tunnel A grille 59 is placed at the entrance to the tunnel.

The products passing through the tunnel heat the table Ducts 60 lead from the discharge end of the tunnel and are con nected with a smoke stack (31. The stack creates a draft so that the products are drawn through the openings in the baffle walls and the opening 56, whereby combustion is promoted in the burning chamber.

Various changes in the size and shape of the different parts, as well as modifications and alterations may be made within the scope of the appended claims.

What I claim, is:

1. In an incinerator, the combination of a burning chamber having a charging hole in its roof and an outlet at one side, a baflie wall in the chamber having an opening therethrough, fire grates extending on each side of the wall, the opening of the wall. extending above said fire grates, and suspension grates on each side of the wall, the opening of the wall extending above and below the suspension grates.

2. In an incinerator. the combination of a burning chamber having a charging hole in its roof, an inclined drying table in the chamber under the charging hole, a battle wall at right angles to the table, suspension grates on each side of the bafile wall con-- tiguous to the table, and fire grates on each side of the battle wall spaced below the suspension grates in front of the table.

In an incinerator, the combination of a burning chamber having a charging hole in its roof, an inclined drying table in the chamber under the charging hole, a bafile wall at right angles to the table, suspension grates on each side of the battle wall contiguous to the table, and tire grates on each side of the bailie wall spaced below the suspension grates in front of the table, the batlie wall having an opening extending above and below the suspension grates.

t. In an incinerator, the combination of a burning chamber, an inclined drying table at the rear of the chamber, baiiie walls extending from the front wall of the chamber to the table, suspension grates between and on each side of said baffle walls contiguous to the table, fire grates under the suspension grates, the battle walls having vertical openings extending above and below the suspension grates, and doors in the front wall giving access to the surfaces of the suspension and fire grates.

In an incinerator, the combination of a burning ehan'iber, a drying table extending along the rear wall of the chamber, the chamber having a charging hole over the table, vertical balile walls spaced from the sides of the chamber and also spaced from each other and extending from the table to front wall of the chamber, the battle walls having connnunicating openings therein, fire grates in the chan'iber separated by the baflle walls and below the front edge of the table, and suspension grates overthe fire grates and contiguous to the table and the openings in the battle walls, the space above the table being unobstructed whereby the hot gases may pass around the rear ends of the battle walls and over the table.

In testimony whereof I affix my signatin'e.
