SMOKE-ABATING DEVICE.
SPECIFICATION forming part Of Letters Patent No. 698,145, dated April 22, 1902.
Application filed August 17, 190i. Serial No. 72,325. (No model.)
TOCLZZ whom it may concern:
Be it known that I, FRED R. SELLMAN, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have inventedacertain new and useful Improvement in Smoke-Abating Devices, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accom panying drawings, forming part of this specification, in which Figure 1 is a sideelevational view of a water-tube boiler, showing'my improved smokeabating device arranged in position thereunder. Fig. 2 is a horizontal sectional View on line 2 2, Fig. 1; and Fig. 3 is a vertical crosssectional view on line 3 3, Fig. 1.
This invention relates to a new and useful improvement in smoke-abating devices designed particularly for use in connection with furnaces, the object being to enable the employment of a device of the character described with furnaces already in use.
Another object is to simplify the construc-' maybe used in connection with various forms andtypes of boilers and furnaces.
In the accompanying drawings, 1 indicates the grate-bars, and 2 the bridge-wall, over which the products of combustion are drawn rearwardly under the tiling 3. At the rear end of the boiler the products of combustion pass upwardly over the tiling 3 and under the tiling 4: and around the Water-tubes. At the front end of the furnace the products of com bustion pass upwardly and over the tiling 4 to the stack 5.
My improved smoke-abating device is arranged behind the bridge-wall; and it consists, generally stated ,in a chamber into which fresh air is admitted, said chamber heating said air, the air finally escaping through lateral openings into the smoke-flue immediately behind the bridge-wall, where .it com-,
l0 and also part of the floor of the draft-flue behind the bridge-wall.
14 indicates tiles supported by the columns 12, said tiles being formed with recesses or seats in their upper faces and openings for the passage of the heated air from chambers 12.
These tiles form the roof of the chambers 11 and also part of the floor of the draft-flue behind the bridge-Wall.
15indicates tile-tubes seated in the recesses in the upper faces of the tiles 14., the bore of said tile-tubes registering with the openings in the tiling 14. The upper ends of these tiletubes are closed by tiling 16, which are preferably provided with circular recesses in their under faces to receive the upper ends of the tile-tubes and close them. These tile-tubes are formed'with lateral openings 17, as shown. By referring to Fig. 2 it will be observed that these tile-tubes are staggered, the purpose of this being to force the products of combustion and heated gases to travel a tortuouspath, whereby the heated air emanating from the lateral openings in the tile-tubes becomes more intimately mixed with the gases passing rearwardly through the draft-flue at this point.
In operation all of the products of combustion and escaping gases from the grate 1 pass rearwardly between and arou nd the tile-tubes, heating the same and by radiation also heating the tiles 14 and 13. The air coming in through the opening 6 is cold when it is received in the distributing-chamber; but in passing through the ducts or passages 10 into the chambers 11 it becomes heated in said passages and in said chambers and upon entering the tile-tubes is further heated, so that when it issues through the openings 17 it is in a highly-heated state--in fact, in readiness to be immediately combined with the combustible gases in order that complete combustion of said gases and the free carbon carried thereby will be elfected.
By referring to Fig. 1 it will be observed that the air-inlet opening (5 is of relatively small area as compared to the chambers and passages through which the air travels, and consequently the air can pass but slowly through said chambers and passages, which will result in the air becoming highly heated before it reaches the tile-tubes and is discharged into the draft-flue. It will be further observed that the openings which connect the rearmost chamber 11 with the passages 10 are relatively large,while the openings which connect the rearmost chamber 11 to the middle chamber ll are smaller, while the openings which connect the chamber 11 with chamber 11 are the smallest. These restricted areas in the openings through which the air is admitted to these chambers enable a proper distribu tion of the air to all of said chambers, so that the tile-tubes receive practically a uniform quantity of air irrespective of their position.
In practice as compared with the available area of the draft-flue the combined area of the openings 17 is about as two-thirds is to onethat is, for one hundred and eighty inches of available flue area the combined area of the heated air-exit openings 17 would amount to about one hundred and twenty inches. This proportion, however, only prevailsin the type of boiler-furnace where there is a large grate-surface, and consequently a large amount of air passes through the gratesurfaee and into the draft-flue, said air retaining its oxygen, so that in contacting with the heated tile-tubes it will materially assist in supporting combustion of the gases by supplying oxygen. However, in other types of furnaces where the grate area is smaller the above proportion might be changed to advantageas, for instance, by increasing the openings in the tile-tubes, through which the heated air passes, so as to exceed the area of the exit-flue. The tile-tubes being placed across the exit-flue not only become highly heated when the furnace is burning normally, but when fresh fuel is introduced on thefire the heat of the tile-tubes is given up, so as to heat the products of combustion, &c., and prevent the free carbon from passing out through the smoke-stack by enabling the heated gases to combine, so that perfect combustion thereof will result. The staggered arrangement of the tile-tubes is also advantageous, in that it causes the heated air issuing from its lateral openings to become intimately mixed with the gases passing over the bridge-wall.
I am aware that minor changes in the construction, arrangement, and combination of the several parts of myim proved smoke-abating device may be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
1. The combination with an air-inlet lead ing to a distributing-chamber, of passages connecting said distributing-chamber with chambers behind the bridge-wall, perforated tiling forming the roof of said last-mentioned chambers, tube-tiles supported by said rool, the bores of said tube-tiles registering with the perforations in the roof, lateral openings in the tube-tiles, and closures for the upper ends of said tube-tiles, substantially as described.
2. The combination with a distributingohamber opening to atmosphere, of passages leading from said distributing-chamber into a plurality of chambers located immediately behind the bridge-wall, said plurality of chambers having gradually-restricted inlet-openin gs, hollow tube-tiles arranged in rows above said chambers, the tubes of one row being staggered with respect to those of the next adjacent row, all of said tubes being provided with lateral openings, and closures for the upper ends of the tubes, substantially as described.
3. The combination with an air-inlet, of a heating-chamber connected therewith and having discharge-openings in its upper portion, said heating-cha1nber being arranged under the draft-flue and rearwardly of the bridge-wall, rows of tubes connected with the discharge-openings in said chamber and traversing the smokeflue, said tubes having lateral openings for the discharge of heated air, and tiling provided with seats for receiving and closing the upper ends of said tubes, substantially as described.
In testimony whereof I hereunto afliS: my signature, in the presence of two witnesses.
FRED R. SELLMAN.
