SMOKE-REDUCING DEVICE FOR FURNACES hpplieatio'n filed October 26, 1929. Serial- No. 402,594.
This invention relates to apparatus for cleaning smoke emanating from furnaces, of dust, solid particles and ,of heavy or bulky,
as well as injurious products of combustion in its passage from the firebox to the delivery mouth of a chimney, smoke stack, or the like; the object of the invention being to provide a simple inexpensive'device for washing smoke, which maybe applied, as an attachment, to the fines of ordinary house furnaces whereby cheaper coal of the lower grades may be burned with satisfactory results both as regards the heat derived and l the demands of the health department laws, 1 but the invention will be applicable also to industrial furnaces, boilers, on ships, etc.
Efiorts heretofore to clear smoke of dust and of its black heavy particles have usualu ly been directed to the employment of superheated staggered fire walls or baflie plates designed to catch and destroy the said black heavy particles of carbon, slag, cinders and the like, said baflie plates being a part of the furnace, which construction has been found inadequate and unsatisfactory, in that, it was complicated, cumbersome and much of the unburnt products of combustion still escaped with the smoke to the open air.
According to this invention the apparatus for cleaning smoke emanating from a furnace or other fire box, may be contained in a suitable casing unit applicable to the usual home furnace smoke flue, said casing being readily 7 installed for service without disturbing the furnace and being easily removed or clean-ed when desired. y
A feature of the invention is found in the provision of a number of smoke flues opening into a distributing chamber at the bottom of the casing and into a smoke washing expansion chamber at the top thereof.
Arranged intermediate the smoke fiues and preferably parallel therewith are steam div recting pipes connected by a series of inclined tubes with the said smoke flues. These steam directing pipes also communicate with the smoke distributing and the smoke washing expansion chambers.
Steamunder pressure is introduced through appropriate nozzles at the bottom of the steam directing tubes, and at the top of these tubes are spreaders to direct the steam laterally over and across the smoke flues to thoroughly saturate or moisten all'unburnt products of combustion so that they become the bottom of the smoke distributing chamher which is provided with side doors through which the mass of segregated dirt may be removed. r
The invention possesses other advantaegous features, which with the foregoing will be set forth at'length-in the following description where I shall outline in full that form" of the invention which I have selected for illustration in the drawings accompanying and forming part of this specification. The nov-' city of the inventionwill be pointed out in the claims.
. It will be understood that I .do not limit myself to the showing made by the said drawings and description as I may adopt many variations within the scope of my invention. I r
The arrangement of the parts may be variedconsiderably and the present embodiment illustrates the invention now thought to be the best form, but, of course, many refinements and changes may be made in the commercial and industrial application of the device provided for the purpose set forth.
In the drawings similar reference characters areemployed to designate corresponding parts in each of the views, in which Fig. l is a semi-diagram1natic side elevation showing theinvention applied to the smoke flue of a house furnace the comparative size of the improved device being somewhat exaggerated Fig. 2 is an enlarged semi-diagrammatic partial sectional elevation, the mixing of the uncleaned smoke with the cleaning steam being indicated by arrows.
. Referring now to the drawings in detail, 10 designates an ordinary house heating furnace, having the usual smoke outlet pipe 11 and hot air and other heating medium ducts or flues indicated at 12.
Suitably carried by the smoke outlet pipe 11 is a casing drum or housing 13, having a short inlet pipe 14 and an outlet flue 15 which may connect with a convenient chimney or smoke stack, not shown.
The casing is preferably divided to provide a smoke distributing chamber 16 at the bottom and a smoke washing expansion chamber 17 at the top, said chamber being connected by communicating smoke flues 18 and steam directing pipes 19, which are cross connected by communicating tubes 20, which are preferably upwardly inclined from the smoke flues so that steam'jets introduced at the bottom 01'? said pipes through a supply pipe 21 and nozzles 22, may serve to draw some of the escaping uncleaned smoke across through the said tubes and into the steam pipes in its upward movement to the washing chamber 17 at the top of the casing.
By this method, some of the smoke is thus thoroughly saturated with moisture before it reaches the washing chamber and the heavy wet unburnt carbons and the like contained in this smoke, when deflected laterally by suitable spreaders or deflectors 23 will immediately fall through the smoke flues to the bottom of the smoke chamber 16, while that smoke passing upwards through the smoke flues 18, will meet the lateral blasts of steam thus deflected across said flues from the pipes 19 and the contained dust, dirt and unburnt products of combustion will become thoroughly saturated and heavy and {all back to the smoke chamber 16, the washed or cleaned smoke continuing on up the, chimney through the flue 1.5.
The inclined cross tubes 20 will also aid in the draft in the smoke flues 18 and the steam. blowing through my device will generally help to increase and strengthen the draft in the smoke flue and chimney.
To conveniently remove the accumulated dirt from the floor of the smoke chamber 16, the wall of the casing 13, is provided with openings 24-. which are closed by suitable doors 25 and opened when necessary. But this usually need only be done at longer intervals.
It is obvious that the principle of my invention may be used with larger heating units, like those of apartment houses, office buildings, industrial plants, power plants, ships, etc.
What I claim as new, is:
1. A smoke washer embodying a casing divided to provide a distributing chamber and a washing chamber, smoke flues and intermediate steam pipes connecting said chambers, tube connections between said flues and pipes, and steam delivery means extending into the bottom of the said pipes, as shown.
2. A smoke washer embodying a casing divided to provide a distributing chamber and a washing chamber, smoke flues and intermediate steam pipes connecting said chambers, tube connections between said flues and pipes, and steam delivery means extending into the bottom of said pipes, as shown, said tube connections being inclined upwardly from the smoke flues to the steam pipes.
3. A smoke washer embodying a casing divided to provide a distributing chamber and a washing chamber, smoke flues and steam pipes connecting said chambers, the flues having flared tops, spreaders at the tops of said pipes, inclined tube connections between the flues and pipes, normally closed openings in the wall of said-distributing chamber, and steam supply means including nozzles extending into the bottom of said pipes, for the purpose set forth.
Signed at New York, in the county of New York, and State of New York, this 11th day of October, 1929.
MICHAEL LIEBERMAN.
