Description
LEON BREWSTER LENT, OF BREWSTER. NEW YORK.
STEAM-BOILER.
Specification of Letters Patent.
I atented May 8, 1906.
Application filed July 8,1905. Serial No. 268.825.
To all whom it may concern.-
Be it known that I, LEON BREWSTER LENT, a citizen of the United States, residing at Brewster, in the county of Putnam and State of New York, have invented a new and useful Improvement in Steam-Boilers, of which the following is a specification.
My invention relates to improvements in steam-boilers, and the object thereof is to produce a simple and compact structure easily built, having an unusually large amount of heating-surface for its size, and means whereby the furnace-gases are kept long in contact with the heating-surface, thereby producing a greater heating effect and a fuller utilization of the heat of the fuel Without a corresponding decrease in the chimneydraft. I accomplish these objects by placing the furnace or throat to one side of the longitudinal axis of the boiler, thereby causin the furnace-gases to pass in a tangentia whirl about the outer surface of the boiler and then an upward course through the tubes or flues inside of the boiler to the smoke-pipe.
In the accompanying drawings, forming part of this specification, Figure 1 represents a horizontal section along line 2 2 of Fig. 2, and Fig. 2 represents a vertical section along line 1 1 of Fig. 1.
The same letters of reference represent the same parts in both figures.
A is a boiler, preferably vertical, which is provided with tubes or fiues B and the smokestack 0. The boiler is surrounded by a furnace-casing D, the furnace E being near the upper part of the boiler and rovided with the usual bridge-wall F, grate fire-door H, and ash-pit door I.
The throat L or connection between the furnace E and annular space J, surrounding the boiler, is preferably contracted at its sides and placed tangential to the boilingshell to increase the velocity of the escapin gases and cause them to take a circular an downward path, whirling a number of times about the outer heating-surface of the boiler before passing upward through the tubes or flues B, as indicated by the arrows in Fig. 2.
Although the furnace-gases will naturally Whirl about the exterior of the boiler in a helical course, to make this action more certain I preferably employ an im erforate helical septum M in the space J, w 'ch acts as a guide for the gases.
The steam preferably is led from the steamspace of the boiler by means of the pipe N, passing downwardly to a header 0, through a series of pipes K, forming a superheater,
to a corresponding header P, and thence through the main steam-pipe Q.
Having fully described the nature of my invention, what I claim, and desire to secure by Letters Patent, is
1. The combination of a boiler and a furnace therefor, located near one end thereof and to one side of the longitudinal axis of the boiler, and a casing surrounding the boiler forming a chamber connected with said furnace whereby the gases pass in a tangential whirl through the chamber and about the boiler, substantially as described.
2. The combination of a boiler provided with flues, a casing forming a chamber about the boiler, a furnace located near one end of the boiler, to one side of the longitudinal axis thereof and communicating with said chamber, whereby the furnace-gases are forced to travel in a tangential whirl or helix about the exterior of the boiler and then through the flues or tubes, substantially as described.
3. The combination of a boiler, a casing surrounding the same and forming a chamber, a furnace, a passage connectin the furnace with the chamber near one end tangentially, whereby the furnace-gases are forced to take a helical course about the boiler and through said chamber, substantially as described.
4. The combination of a vertical tubular boiler, a casing surrounding same, and a furnace commumcating tangentially with said chamber near the upper end thereof, whereby the furnace-gases are caused to take a helical downward course about the boiler and through said chamber before passing upwardly through the boiler-tubes, substantially as described.
5. The combination of a boiler and a furnace therefor located near one end thereof and to one side of its longitudinal axis, a casing surrounding the boiler and leaving an in tervening space, a helical septum 1n said space, said space communicating with the furnace, whereby the furnace-gases are forced to pass about the boiler in a helical path, substantially as described.
6. The combination of a boiler provided with flues, a casing forming a chamber about the boiler, a helical septum in said chamber, a furnace located near one end of the boiler and to one side of the longitudinal axis therepath about the boiler, substantially as described.
8. The combination of a Vertical tubular boiler, a casing surrounding same and forming a chamber, a furnace communicating I 5 tangentially with the upper end of said chamber and a helical septum in said chamber whereby the gases are forced to take a helical, downward course about the boiler and then pass upward through the tubes of the boiler 20 to the smoke-stack, substantially as described.
