UNITED STATES CHARLES UEBELMESSER, OF NEW YORK, N. Y.
STEAM GENERATOR.
Application filed July 22,
The object of my invention is to afford simple but effective water heating and boiling means in which the caloric imparted thereto is utilized to a maximum degree for the generating of steam expeditiously and eeonomically,and to this end the invention consists essentially in the combination and arrangement of elements and devices described and claimed, whereby these and other advantageous results are attained, distinctive features being the positioning of a heating unit medially between superposed primary and-secondary tubular water boiling elements through which the gaseous products of combustion are drawn by a draft flue common to both, and the provision of means whereby a continuous automatic water circulation is attained and insured between the said primary and secondary water heating elements, all as hereinafter fully set forth.
In the accompany-ing drawing, which is a sectional elevation diagrammatical in character, I illustrate a practical embodiment of the essential features of my invention in steam generating apparatus such as designated, although I do not limit myself to the identical construction and arrangement of parts thus shown by way of exemplification, since changes may be made in minor details, and equivalent mechanical expedi: ents resorted to, with like results, and without departing from the spirit and intent of my invention in this respect.
With this understanding P, represents a lower primary water heat-- or, and S, an upper secondary boiler and steam generator, B, representing a heating element interposed between them, and consistin r of, a suitable burner liavin nozzles both in the top and bottom thereot through which the fuel may pass thereby to cause flames to impinge against the top of the primary water heater P, and against the bottom of the secondary boiler and generator S, as shown, said burner B, being supplied with gas, by a pipe I).
The primary water heating element P, is formed with vertical flue tubes p, for the passage of theproducts of combustion from the burner B, downward to the lower branch F, of the main exhaust flue F. The burner B extends across substantially the entire space between the water heater P and the generator S and acts as a bafile between the upper and lower flames, which flames are 1926. Serial No. 124,198.
projected both upwardly and downwardly by the pressure of the fuel to impinge directly against thelower wall of the generator S and the upper wall of the heater P, respectively. In like manner the secondary boiler and steam generating element S, is formed with vertical flue tubes 8, 8, through which the products of combustion emanating from the burner B, pass upward to the up per branch F of said main exhaust flue F.
Because of the bafiiing function performed by the burner and also because ot-the fact that the upper flue tubes 8, s, which carry oil the combustion gases through the generator S have not sufiicient capacity to carry oif all of the gases from both the top and bottom flames, and furthermore because the fuel is projected outwardly from the burner under pressure, practically all of the combustion gases from the lower flames will pass downwardly through the lower flue tubes 1), p. A drain pipe 8 is provided at the lower part of the generator S for permitting the.
water tobe drained therefrom and for cleaning out purposes, said pipe being furnished with a valve or shut oii' cock s Water is supplied to the lower part of the primary water heating element P, by a feed pipe controlled by a valve 10 and the upper part of said primary water heating element P, is connected with the lower part of the secondary boiler and steam generative element S, by a coupling pipe 0, said steam generative element S, being also connected with the primary heating element P, by means of a return pipe 0', extending from the bottom of said secondary heating element S, to approximately the bottom of the primary heating element P, substantially as indicated on the right of the arrangement of parts shown in the drawing, although this identical positioning of the pipes iii) c, c, is not essential, provided they'function as intended as means of effecting an automatic and continuous circulation of water between and through both water heating elements as clearly indicated in said drawing.
It is to be noted in this connection that the latter, and this result is fur er promoted eneration' in by the automatic circulation of water between and through both the heating elements P, and S, whereby my duplex heating system is adapted to the rapid generation of a maximum quantity of steam in a minimum of space and capacity, thereby rendering the same specially useful for steamdriven automobiles and vehicles generally, and for analogous uses where economy of space and fuel combined with prolific steam production is a desideratum.
The operation of the boiler will be as follows: T he burner B being lit the downwardly directed flames issuing Irom the bottom of said burner will impinge directly upon the top of the primary heating element P and, asthis element is tilled with water, the water in contact with the top thereof will be quickly heated to a high temperature and will immediately pass upwardly through the pipe 0 to the upper secondary or steam generating element :55, to be further heated in the element S by the uppermost flames of the burner. The combustion gases from the lowermost burner flames in passing through the flue tubes p gradually heat the body of water in the element P and as the water at the bottom of said element is quite cool the major part of the heat is extracted from said gases by the time they issue from the bottom of said tubes After the burner has been in operation but a short time the water in the lower element P is heated sufficiently, both by the flue gases passing through the tubes 39 and the passage of some of the highly heated water through the pipe 0 from the upper element to replace the water which passes upwardly through the pipe 0,.
so that the water at the top of the element P is practically instantaneously heated to the boiling temperature by the heat of the direct flames, there being no lag in the heating effect because of the setting up of convection currents such as are produced when the heat is applied from beneath an element containing water to be heated Obviously, an important factor in my sys tem and means for rapid steam generation, is the positioning of the burner B, between the primary heating element P, and the secondary or steam generative element S, 111 conjunction with the drawing ofl of the products of combustion through the fines thereof, and discharge of said gases through a main exhaust, as set forth.
I have herein shown and described the heating element B, as consisting of a gas burner as a unit, although other heating means might be substituted therefor, under certain conditions and requirements, with es sentially like results, the distinctive feature in this respect being the interposition of a heating element between the superposed sections of a duplex boiler, in which one see tion is arranged'above the other and the heat from the burner is directed both upwardly to heat the upper section and downwardly upon the top of the lower section which is filled to said top with water.
