FREDERICK W. LINAKEB, OF DUBIS, PENNSYLVANIA, ASSIGNOR TO THE VULCAN 'SOOT CLEANER C0., 0F PITTSBURG, PA.,

TION OF NEW JERSEY.

OF DUBOIS, PENNSYLVANIA, A CORPORA- FUEL-ECGNOMIZER SCOT-CLEANER.

Application le .november 3, 18M.

To all wimme't may concern Be it known that LFREDERICK W. Lin- AKER, a subject of the King of England', residing at Dubois, in the county of Clearfield, and State of Pennsylvania, have invented certain new and useful lmprovements in Fuel-Economizer Scot-Cleaners', of which the following is a specification.

This invention relates to improvements in fuel-economizer soot-cleaners and has for its primary object to provide in an economiser, a' cleaning fluid distributing pipe or pipes for directing a cleaning fluid, preferably steam, upon the exterior surfaces of the tubes of the economizer whereby to elfectually free the latter of soot.

A'further object 'of the invention is to provide in an economizer, a fluid distributing pipe or pipes so constructed and arranged as to discharge the cleaning fluid between the rows of tubes of the economizer in streams along lines or paths oblique to the axis or axes of the distributing pipe or A still further object is to provide in an economizer, a soot cleaning means in the form of a fluid-distributing pipe or pipes adapted tc discharge cleaning fluid in oblique jets or streams, and capable of oscillatory movement whereby to cause said distributing 'pipe or pipes to vary the angularity or Obliquity of the streams of cleaning fluid, thereby adapting the latter to cover a wide radial area and to thus effect the re# moval of accumulated soot from all of the rows of the economizer tubes.

Fuel economizers, as is well known, are utilized for the purpose of heating 'water preliminary to its introduction into the boiler, and for this purpose use is made of the waste gases and other products of combustion, the economizer beinOj generally located in the path of travel or such production leading from the boiler or boilers to the chimney or stack, the economiaers comprising a plurality of spaced vertically-extending tubes, the upper and lower ends of which are connected by headers to provide a circulation of water therethrough. As the tubes are located in the path of travel of the products of combustion, the outer surfaces of the tubes quickly collect soot particles carried by such products, destroying thevmaximum application of heat to the tubes.

Toorn. e the abete and other objections t of econoniizer tubes by a 70 scraping as heretofore stated, a distributing pipe or pipes for a cleaning fluid, capable of being operated at rmy time without closing down the operation of the furnace or the economizer, and v lich in operation in addition to eflectually Vleaning the economizer tubesof` soot, aid the naL ual draft in carrying olf the removed parti"l es, and enabling me at all times to pr e a maximum amount of service fro l e economizer.

The na the invention will be readily under` as the saine is hereinafter disclosed 4 the said invention consists in the construction, combination and arent of parts, hereinafter fully descrioed, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

ln the drawings, in which 'similar reference characters indicate similar parts in each of the views: Figure l is a side elevation partly broken away of an economizer of the well-known ,Sturtevant type, with a soot cleaner in accordance with my invention applied thereto. Fig. 2 is a plan view of the saine partly broken away.

A fuel economizer of the Sturtevant type comprises a jacket or setting 1 which incloses the vertically-disposed economizer tubes 2 connected in the usual manner at the upper and lower'cnds by headers 3. The tubes 2 in this typeof an economizer are in staggered form or relation, and in order to effectually remove the accumulated soot from the tubes, it is necessary to project the cleaning agent between the tubes in streams or paths oblique to the axis or axes of the distributing pipe or pipes that is arranged among the tubes forcleaning purposes.

In the here chosen illustration of my in' ventionh I have shown two distributing pipes 4 arrapged one above the other in vertical longitudinal alinement, these pipes being journakf` in'bea'rings 5 on the opposite side walls of the setting or jacket 1. Obviously, but a single pipe, or as many of the pipes as desired may be arranged, according to the size of the economizer in which the cleaner is arranged. Whether there be one or more pipes, each pipe is closed at its inner end, its outer end being in communication with a branch pipe 6 connected with a supply pipe 7, which latter\\is provided with the usual shut-off, drain valve, etc. Each branch pipe 6 is also provided with a shut-off valve 6. Each pipe 4 is 'provided with spaced nozzles 8 so disposed witharelation to the aXis ofthe pipe, that the cleaning agent is directed in jets or streams alon oblique paths or lines between the rows o tubes 2 to remove accumulations of soot from tlieouter surfaces of the tubes, these oblique paths or lines upon whichthe jets or streams of the cleaning agent are'projected, being clearly illustrated in F ig. 2 of the drawings, the lower pipe projecting the jets or streams as shown by full lines and arrows, the upper pipe projecting the jets or streams as shown by l' broken lines and arrows, so that the streams from the one pipe intersect and cross the paths of streams from the other pipe.

In order that the pipe or pipes 4 may be oscillated or partially rotated, the outer ends of these pipes connect by means of a swivel joint 9 withI the branch pipe 6, suitable means being providedv for operating the pipes 4. 4This means obviously may be a handwheel 13 on each pipe 4, as shown on the lower pipe in Fig. 1, or itmay be a means as shown on the upper pipe in Fig. 1

consisting ofA a sprocket wheel 10 upon the pipe 4, over which passes a sprocket chain l1, having the ends connected to rods 12, these rods projecting down to a point where they are within easy reach of the operator and provided on other lower ends with hand pulling alternately on the rods 12 the pipe is revolved as desired, and since the nozzles 8 are disposed around the pipe or pipes 4 and are so disposed that their discharge ends are oblique to the axis of the pipe, the jets or streams of cleaning fluid are projected on oblique lines between the rows of tubes 2, the oscillating movement of the distributing pipe or pipes'varying the radial paths or the streams of fluid issuing from the discharge nozzles-insuring a thorough cleaning of the water circulating tubes of the economizer throughout their length, such wide diffusion of the cleaning fluid permitting it to permeate all of the spaces between the water tubes and any surfaces within the economizer casing or setting where soot may find lodgment.

It will be understood that the invention'is susceptible to modifications in its structural details, such as in the manner of operatingl the distributing pipes, and in the number or distribution of these pipes among the tubes so as to effectually clean the latter, and like modifications as may fall within the terms and scope of the invention as claimed.

What I claim as new is The combination with a fuel economizer system having rows of vertical water-circulating tubes and Alocated in the path of travel of the products of combustion, the rows of tubes being in staggered relation, of Huid distributing pipes rotatably mounted in the casing of the economizer and disposed between the said tubes, nozzles carried byeacn pipe and disposed around the pipes to discharge cleaning fluid in jets orstreams on lines or paths oblique to the axes of the pipes,said nozzles also disposed to project the iuid in the spaces between rows of tubes,

,the nozzles carried by one blow pipe being arranged to project the cleaning Huid on paths or lines which intersect and cross thepaths or lines of streams of cleaning fluid issuing from another pipe, and means for rotating the pipes to vary the angularity of said jets or streams'with respectv to the vertical aXes of water-circulating tubes.

In testimony whereof I aix my signature in presence of twov Witnesses.
