Description

TOZABURO SUZUKI, OF SUNAMURA, JAPAN.
VERTICAL BOILER.
Specication of Letters Patent.
Patented Oct. 25, 1910.
Application filed April 9, 1909. Serial Nzo. 488,919.'
To all whom it 'may concern:
Be it known that I, TOZABURO SUzUKI, a subject of the Emperor of Japan, residing at No. 401 Jibeishinden, Sunamura, in the county of Minalni-Katsushika, in the Province of Tokyo, Japan, have invented a new and useful improvement in Vertical Boilers, of which the following is a specification.
This invention relates to improvements in vertical boilers of that charactel.' comprising a steam chamber and a'water chamber inclosed in a boiler structure.
The. .invention consists in the provision of passages in the water chamber for the products of `combustion and the construction ot' the water chamber to the end that the greatest possible efficiency of heut may be obtained.
The invention will be more fully de-` scribed in connection with the accompanying drawings and lwill be more particularly pointed outl in and by the appended claim.
In the drawings Figure 1 is a vertical sectlnal' view. Fig. 2 is a vertical sectional view on line 2-2 of Fig. 1.
Like numerals of reference designate.
similar parts vthroughout the different tigures of the drawings.
As shownin the drawin the usual surrounding boiler structure 1s indicated as a whole at 1, and is provided with a main or `inlet passage 2 v'ireferalably horizontally disposed, which vers -to an extension or as shown a downward passage 3. .An ingress passage et delivers to the stack or other suitable outlet (not showin) 'for the products of combustion. A steam chamber 5 is disposed in the structure I, in a manner to intersect the main passage 2, or the u per wall 6 thereof, so that the products combustion flowing through said passage will play. upon the lower wail of said chamber. f. A water chamber? 'is disposed in the structure 1 in a manner to intersect the lower wall 8 of the'passage 2 so that the products Ofcombustlon will play uponthe upper wall 9 of the chamber 7. Said chambers .5 and 7 are connected by tubes 10kk which extend across said passage 2 and in the path of the products of combustion passing therethrough, in a .manner to be ctl'ectively acted upon. If desired the chambers 5 and 7 may also be connected by jav relatively* large tube il provided with an inner tube 12 dlsposed i the chamber 'I3 which .action will effectivelyA enhance water circulation.
In the forni shown. the water chamber T is 'provided with a single combustion fine 26. As shown the flue .6 is constructed in a manner.to retard the flow oflthe products of combustion therethrough so thaty the contents of' t-he chamber T will t-akepup or absorb as much as possible of the heatthereof but such retardation of theprogress or flow ot' the products ot' combustion not sotticient to'interfere with au vill-tive draft. As shown the lluc- 26 is gradually reduced in size from its 'intake end .27 to its outlet end 28 and may be conical in form as shown. In order to further increasethe heating action a water tube 2) may be disposcdin the path ot' the products of combustion passing through the [luc 26. The tube 29 is in the forin of an inverted truncated cone so that the water will be retarded at the entrance and may freely liow through the larger end as it is more rapidly heated. The larger upper end of the tube 29 also presents a greater area to the water above the saine and the weight thereof will tend to retard upward How-through the' tube 29 but the heut towhich this tube is subjected will off-set any retardation caused by the weight of water above said tube.
