PETER M. W ICKSTRUM AND CECIL M. WICKSTRUM, OF LINCOLN; NEBRASKA.
SPARK-ARRE STE R.
Specification of Letters Patent.
Patented May 19, 1908.
Application filed December 30, 1907. Serial No. 408,614.
T 0 all whom it may concern:
Be it known that we, PETER M. WICK- STRUM and CECIL M. WIoKsTRUM, citizens of the United States, residin at Lincoln, in the county of Lancaster and rtate of Nebraska, have invented a new and useful Spark-Arrester, ofwhich the following is a specification.
This invention relates to spark arresters, the same being designed for use in connection with furnaces of any form from which.
cinders and the like are discharged with the gaseous roducts of combustion.
The object of the invention is to rovide means whereby ,said products of com ustion while passing through the outlet stack of a furnace may be given awhirlin motion so that all heavy particles embodied therein will be thrown beyond the wall of the stack by centrifugal force while the gaseous products which maintain a central position within the stack are free to pass out in the usual manner.
Another object is to provide means where by the exhaust can be utilized for giving an unpulse to the products of combustion and thus increase the effect veness of the spark arrester by increasing the whirling action of the combustion products.
A still further object is to provide means whereby the whirling action can be gradually increased toward the discharge end of the stack to insure separation of the solid and gaseous substances immediately prior to the emission of said products from the stack.
Another object is to provide means whereby the whirling action of the gaseous products is checked immediately subsequent to the separation of the solid particles therefrom so that said gaseous products may be projected a considerable distance beyond the end of the stack as a result of the force with which they are ex elled from the stack. a With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.
'In the accompanying drawings is shown the preferred form of the invention.
In said drawings: Figure 1 is a section through a stackembodying the present improvements parts of the device being shown n elevation; Fig. 2 is a plan view thereof. Fig. 3 1s a section through a slightly modified form of spark arrester, portions of the device being shown in elevation.
Referring to the figures by characters of reference, 1 designates a furnace of any desired structure and having a cylindrical outlet stack 2 the upper end of which is slightly flared as indicated at 3. Within this stack I is provided means whereby a whirling action may be im arted to the products of combustion while fieing projected through the stack, said means consisting preferably of two or more concentric worms or helices 4 of the same diameter as the internal diameter of the stack and extending up to the outletend of said stack. A jacket 5.surrounds and is spaced from the stack 2 and is rovided at its upper end with a hood or en argement 6 having a central opening 7 which is preferably of the same diameter as the internal diameter of stack 2. This opening is surrounded by a tubular extension 8. Hood 6 is preferably curved downwardly so as to lap the flared portion of the stack 2. An exhaust pipe 9 is preferably located within the lower ortion of stack 2 for directing exhaustec steam into the stack and oneor more transverse partitions 10 are located longitudinally within the tubular extension 8 for the purposes hereinafter set forth. Outlet passages 11 extends from the lower end of acket 5 and the collected cinders, etc. are designed to be discharged through these passages.
It is thought that the operation of the device herein described will be fully understood from the foregoing description when read in connection with'the accompanying drawings. The products of combustion upon entering the stack 2 are brought into contact with the helices 4 and are forcibly expelled through the stack by the steam exhaust from pipe 9. The helices impart a whirling movement to the roducts of combustion and as the, solid pro ucts are of greater specific gravity than the gaseous products they will hug the inner surface of t e stack 2 and be drawn outwardly by centrifugal force as soon as they enter the flared portion 3 of the stack. They will thus be caught by the inverted up or portion of hood 6- and deflected downwar as indicated by arrows in Fi 1 into the jacket 5 and thence through out ets 11. The gaseous roducts do not follow the course taken by t e solid products but instead whirl upward into the tubular extension 8 where this combustion products can be accelerated by.
bringing the coils of the helices closer together toward the outlet end of the stack as indicated in Fig. 3. solid products from the gaseous products is thus rendered more effective.
Although but two concentric helices have been disclosed in each construction illustrated it is to be understood that if preferred one, or more than two, may be utilized in lieu thereof.
What is claimed is:
A s ark arrester comprising a stack having a ared outlet end, a jacket surrounding and spaced from the stack, said jacket having an annular outlet at its lower end, the
The separation of the 5 1 upper end of said jacket being enlarged and immovably mounted within the stack for imparting a whirling action to combustion products passing through the stack, the partitions constituting abut-merits for stopping the whirling action of the roducts.
In testimony that we 0 aim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.
