. 3 Claims.
My invention pertains to certain features of novelty and betterment in boilers and relates more particularly to water-heating coils in the boilers, such, for example, as are employed for the supplying of hot water for domestic or other purposes.
-An aim of the invention isth'e provision of an appliance of the specified character in which the parts are "so formed and related to one another 'that'the structure possesses substantial and material advantages in simplicity of construction, economy inproduction, ease of assembly, and, more especially, eificiency in operation.
To the attainment of these and other desirable objects and purposes, the tubes of the boiler through which the hot products of combustion flow are so positioned with reference to one another not only to secure marked and outstanding efiiciency in the operation of the boiler, but also with their upper ones, just below the water-line of the boiler, spaced apart sufiiciently to accommodate the water heating coils which at their front ends are associated or joined with a higher supporting plate or member.
Such spacing or separation of the tubes permits the heating coil either to be located in the space indicated or the provision of such space allows the coil to be otherwise satisfactorily positioned.
That is to say, the water-heating coil need not necessarily actually and completely occupy such space, but the latter, nevertheless, permits the coil tobe located in a position which it could not otherwise occupy.
To enable those acquainted with this art to understand the new invention, both from structural and functional standpoints, a present preferred embodiment of the same is illustrated in the accompanying drawing forming a part of this specification and to which reference should be had in connection with the following detailed description, like reference numerals being employed to designate the same parts of the structure throughout the several views.
In this drawing:-
Figure 1 is a front view of a boiler equipped with the present invention and with one of its doors open;
Figure 2 is a side view of the boiler partly broken away to reveal a portion of its interior construction and with the specified door in closed position;
Figure 3 is a perspective view of one type of heating-coil assembly for use in the boiler; and
Figure 4 is a similar presentation of a slightly different or modified form of water-heating coil.
Referring to the views ofthe drawing,'it willbe noted that the front wall I I of the boiler has the usual or a suitable number'of' hinged doors I2, l3 and M of which the uppermost one I2 is illustrated in open position in Figure 1 disclosing the plurality ormultiplicity of fiues or tubes 15 grouped in the manner shown and extended through the common front-head or tube-sheet IS, the internal structure ofthe boiler being ofmore or less standard or-any suitable construction except for the arrangement and disposition of the tubes I 5 which are arranged to leave a space inthe transverse central part of the boiler between the tubes of the topmost row, all as is clearly shown in Figures 1 and 2, the water-line or water-level above these tubes being indicated by the dotted line H.
Above such water-level line, the front plate or wall H has an aperture l8 therethrough accommodating a suitable frame Is to which is screwed or bolted a plate 2| forming the front of, and I constituting one main supporting member of, the heating-coil assembly, comprising in addition to such plate a single-row metal pipe-coil 22 having upwardly-sloping tubular terminals 23,
24, mounted in any approved manner on the plate 2| as in the usual way indicated in Figure 3. The opposite end of the heating-coil is supported in any convenient manner as by an appropriate member I22 mounted on the tubes.
The construction is such that when the heating-coil-assembly is in place, plate 2| covers and closes the opening through the frame l9 and the coil proper 22 occupies horizontally the space between tubes of the upper row, all such tubes, and the heating-coil proper of course, being below the water-level, whereby the water in the boiler is heated in the usual Way by the hot combustion gases flowing through the tubes and the water in the boiler heats the contents of the coil.
A cold water inlet or admission pipe 25 is connected to one of the terminals 23 or 24 and a hot-water discharge-pipe 26 is joined to the other terminal, whereby the water to be heated enters the submerged coil through the inletpipe and after being properly raised in temperature by the surrounding hot water in the boiler is delivered to point or points of consumption through the delivery pipe, all as will be readily understood.
Instead of using a coil-assembly with a single row of pipes connected together, as illustrated in Figure 3, a similar coil 21, as shown in Figure 55 4, composed of a double row of pipes suitably joined together in series relation may be employed.
From the foregoing description and the accompanying illustrations in the drawing, it will be apparent that the water-heating coil is located just below the water-level in the boiler, this being the locality where the boiler water temperature is the highest, such placing of the coil in this most advantageous position being rendered possible by the spacing of the upper,- most tubes in the manner fully shown.
The transfer of heat from the water in the boiler to the water in the coil creates a desirable circulation of the boiler water due to the fact that the colder water, by reason of the convection currents created, descends toward the bottom of the boiler and the water of higher temperature rises to the top. 7
It has been found that greater heat transmission results when theheating-coil is located just below the water-level and it is for this reason that the tube separation or spacing has been resorted to inorder to accommodate the heating-coil in the situation depicted.
Those skilled in this art will readily understand that the invention is not limited and restricted to the precise and exact features of con,- struction presented hereinabove and that various modifications may be resorted to without departure from the substance or spirit of the in vention claimed hereinafter and without the sacrifice or loss of the substantial benefits and advantages accruing from its employment.
I claim:
1. The combination of a boiler having a plurality of tubes for the flow of the hot combustion gases therethrough with the uppermost tubes spaced apart substantially horizontally for the accommodation of a water-heating-coil, a water-heating-coil at least in part in said space, said uppermost tubes and said coil being below the water-level in the boiler, means to admit the water to -be heated into said coil, and means to deliver the heated water from said -coil.
2. The structure presented in claim 1 in which a wall of the boiler has an aperture therethrough at a higher elevation than the 'water-level in the boiler, in combination with a plate secured in position closing said aperture, and in which structure said means to admit the water into said coil and to deliver it therefrom comprise upwardly-directed pipes connected to the ends of said coil and :mounted on said plate.
.3. The structure presented, :in claim .2 :in which ,a wall of the boilerwhas an aperture-therethrough at a higher elevation than the waterlevelin the boiler, :in combination with a plate secured in position closing said aperture,v and in which structure said means to admit the water into :said coil and to deliver it therefrom comprise upwardly-directed pipes connected to' the ends of said coil and mounted on said plate.
