Lette/rs Patent No. 101,7 67, dated April 12, 1870.
IMPROVEMENT IN STEAM-GENERATORS.
The Schedule referred to in these Letters Patent and making part o( -the same.
To all whomit may concern Be it known that I, MICHAEL RrrcHEr, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and improved Steam- Generator and I do hereby declare that the 'following isa full, clear, and exact description thereof, which will enable others skilled in the artto make and use' the same, reference being had to the accompanying drawings forming part of this specification, in which- Figure l represents an end view of my improved steam-generator.
Figure 2 is a side view, partly in section, ot' the same. v
Similar letters of reference indicate correspomling parts.
This'invention relates to a new steam-generator, which is so' constructed that the water before it enters the .main boiler will be thoroughly heated, and that, when the-pumping ceases, a complete circulation will be kept up in the same..
The sides of the fire-box are formed by hollow water-boxes A A', made of i iron, and set up vertical', as shown in iig. 1, the main boiler B being arranged between them.'
The boiler is 'of suitable construction.
On the inner edges of the boxes A A are arranged p zigzag pipes G C respectively, the upper parts of the two pipes being, under the boiler, connected-with each other by a transverse pipe D.
The feed-water first enters the lower end ot' the pipe C, where a cock, a, is opened for its reception.
It passes then through the pipes C, D, and C', and is heated therein preparatory to entering the box A'.
From the lower end of the pipe Gihe water Hows into the-lower partei' the box A', andis therein further heated.
Through .a short pipe, b, it flows from the top of A into the boiler 13.
From the bo'rier the colder water. Hows down through a pipe, d, into the box A, and the most heated contents of the latter flow through another pipe,
e, fromthe top of the box A back into the boiler. Thus, the water is frequently passed around the firebox to absorb as muchA heat as possible. A pipe, E, extends from the boiler to Ythe loweil end of the pipe C.
While water is pumped into `the apparatus the cock f in the pipe E is closed.
Then pumping, however, ceases, the` cock a is closed andb opened, and then a complete circuit is provided to ena-ble thewater to return to the lower end of C, and to pass up again in thev same, and thus circulate through the entire apparatus.
By connecting the lower end of the pipe C with the boiler B, the boxes A A may be omitted and the pipes C C D E used, and, by omitting the pipes C C D, the boxes A A may be used, but the best resultsare obtained when bot-h pipes and `noxes are used together.
It will be observed that the primary objects Iof'. this invention are two, namely, to provide the boiler with hot water in the ist place, and subsequentlyto utilize the heat product ofthe fire-box. rlhe first I accomplish by causing the water, as it is pumped in, to pass through a series of heated 4pipes and then into a hot chamber before it finds its way into the boiler. It is pumped into pipe C, through which and the 'pipes D C it passes into chamber A', from whence it is conducted in a heated state in'to the boiler through the induction-pipe b.
vAt the time of its entrance into the boiler it is hot, but hasnot attained a" temperature togenerate steam. y
' After the requisite supply has been pumped in, the next object is to convert it into steam with the minimum expenditure of heat.
By allowing the water to circulate not only'against the heating-surface of the.boi1er but also through the pipes and water-chambers, all under the direct and immediate influence of the iirealmost the entire heat force is cconomized.
As the water in these pipes or chambers attains` a temperature exceeding that in the boiler, it at once rises through the intermediate pipes to the boiler, and to the surface of the wetter therein.
In other words, the more highly heated and expanded particles will always rise to the top of the boiler, exact-ly in the same manner and on the same principle as if the pipes, chambers, and boiler were all one vessel.
The cooler stratum of water always being lowest, that in the boiler will sink through the pipe d and through the chamber A until it reaches the bottom thereof, or water, of its own or less temperature.
0n the other hand, as that in A becomes highly heated by its close proximity to the fire, it will rise up through that chamber and pass into the boiler through the induction-pipe e.4
The auxiliary pipe E is employed as an eductionpipe to connect the boiler with pipes C D O', so that cooler portions of the water mayfnd their way to the heating-chamber A'. From this, when suiiiciently heated, it passes through induction-pipe i: to the boiler.
Having thus described my invention,
I claim as new and desire to secure hy Let-ters Batent- 1. Supplying hot-Water to a steam-generator by means of a heating-chamber, A', and series of wind. `ing pipes all placed contiguous to the re, whereby the water is retarded in its progress :md heated before it reaches the boiler, as set forth.
2. The combination with boiler of inlets and outlets 'b d e, chambers A A', and pipes C C' D E, all arranged with respect to the furnace iu the manner described.
The above specification of my invention signed by me this 3d day of August, 1869.
