JOHN w. McNEAL, or CHICAGO, ILLINOIS.
SMOKE-CONSUMING FURNACE.-
I Specification of Letters Patent.
Application filed December 29, 1909. Serial No. 535,488.
To all whom it may conqm: v
Be it known that I, JOHN W. MoNEAL, a citizen of the United States, residing at Chi- 'cago, county'of Cook, and State of Illinois,
have invented certain new and useful 1m provements in Smoke-Consuming Furnaces,-
of which the following is a specification.
' Y My invention relates to smoke consuming furnaces and more particularlyto a smoke igniting arch for steam boiler furnaces, the object being to produce an improved deviceof this character which shall be capable of withstanding intense heat without collapsing, it being well known that ordinary igniting arches are short-lived and require'frequent renewal.
A further object of my invention is to so 'design the arch that the fire-brick tiling nates the used in its construction may be' readily placed in position when a complete arch is being constructed or when renewals are beiiig made in case of damaged bricks.
Other objects will appear hereinafter.
With these objects in viewmy invention consists in the novel construction and arrangement of parts which will be hereinafter fully described and more particularly pointed out in the appended claim.
My invention will be more readily understood byreference to the accompanying.
drawings forming a part of this specification, and in which, 7
Figure l is a transverse section of a boiler and furnace taken on line mw of Fi 2, the latter being substantially a longitu inal section showing the traveling fire grate diagrammatically and the ignitlng arch in elevation, Fig. 3 is a vertical longitudinal sec,-
tion of the arch taken on line z--a of Fig. 1, Fig. 4 shows a section of the arch taken on line yy of Fig. 3, Fig. 5 is a view of. a fire-brick used adjacent the rear end of the arch and a section taken online y y of Fig. 3, Fig. 6 is a front elevation of a rearmost fire-brick, and Fig.7 is a detail front elevation showing the front arch manifold and supporting pipe construction.-
Referrin now to the drawings 1 desigront end of an ordina boiler and 2 the usual side wallsfidesignating a transverse ,wall su' ported by the side walls and on which t e boiler rests. The front wall 4 is provided with a series of horizontally extending perforations ,5, only one of which is shown, through which air may flow to the chamber 6 when in.
steam flow of air being explained hereinafter. A curved roof 6 of tile or other refractory material is provided which forms a top to the chamber 6, and the same is supported by the side walls 2. A traveling fire grate 7 of usual duced by the fire draft, the object of this,
Patented Feb. 7,1911
construction is provided and the same is indicated diagrammatically in'the drawings as aforesaid. r
Arranged above the grate 7 is my improved smoke igniting arch 8 which is formed flat as shown in preference tothe more common curved form. This arch is provided with a front manifold 9 and a rear manifold 10 which are connected res ectively to the supporting pipes 11 an 12 which lead to the boiler 13. Longitudinally extending pipes or tubes 14 connect the manifolds 9 and 10, as shown in Fig. 3, in order that water may throughout the'pipes in the arch and to prevent the pipes from overheating and thus rendering the same weak and liable to collapse under the weight of the fire-bricks 15 and 15 resting thereon.
The arch 8 may extend rearwardly into the boiler space any desired distance and the same preferably extends upwardly as well as rearwardly, thereby accommodating the' increasing volume of gases or products of i circulate freely combustion at the rear of the fire. The arch 8 is formed flat as shown in the several figures inorder that the same may contact with the smoke uniformly, thereby producing results which are unobtainable with a curved arch.
The fire-bricks 15 and 15 are so formed that they may be hooked over the tubes 14,
and thus secured inpositi0n,.and they may "be spaced apart as shown in Fig. 3 to permit air to pass downwardly from the chamber. This air coming into contact with the smoke that their outer upper corners are rounded as shown. Brlcks 15' are formed to. partially encompa'sssaid tubes on the-top, have narrow lower portions ada ted to fit between the lower portions. 0 bricks 15 and under the arch renders the smoke combusare provided at their outer upper corners i with a rounded projection adapted to engage over the outer rounded corner of the adjacent brick 15. The brick shown at the extreme left in Fig. 4 is of the same general form as bricks 15 but has no projection at its outerupper corner, thesame being squared off at a right-angle as shown. -.By this construction the said bricks may be in-.
serted into position on tubes let from below,
beginning at the right of Fig. {l and proceedmg :toward the left, the brick 15"- being dropped from above between the last tube on the left and furnace wall 2,.thus'serving to lock all bricksin position. Likewise, all bricks may be readily removed after brick 15" has been removed from above.
' The'pipes 14 may be secured in'the manifolds 9, and 10 in any suitable manner, the plugs 16 being provided in order to allow the replacement of a single pipe when necessary. The fire- bricks 17 and 18 are specially ates with the arch 8 in preventing heat from distorting the tube-sheet or front of the boiler and that in case of failure-of the arch that saidroof would serve as a temporary protection -preventing serious. damage.
While I have shown what I deem to be the preferable form of my improved smoke consuming furnace, I do not wish to be limited thereto as there might be various changes made inthe details of construction and arrangement of parts described without departing from my invention and hence I desire to avail myself of such changes and modifications as fairly fall within the spirit and scope of the appended claim.
Having described my invention what I claim as new and desire to secure by Letters Patent is:
A fire arch consisting of a series of water tubes; a series of larger fire bricks formed to partially encompass a tube at the top, substantially entirely encompass it at the bottomand having their outer upper corners rounded; a series of smaller fire bricks having narrow lower portions adapted to fit between the lower portions of said larger bricks and upper portions partially encompassing the tops of said tubes at one side and having projections at the upper corners of their other sides adapted ,to engage the rounded corners of said larger bricks; and
a' terminal brick similar tosaid smaller bricks exceptthat its outer upper corner is squared off at right angles, substantially as described.
. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN w. McNEAL.
