HEATING DEVICE.

Application led July 10, 1922. Serial No. 574,052.

The present invention relates to improvements in heating devices more particularly intended for use in systems in which hot water or other liquid, or steam or other vapor is employed for house or industrial heating. It will be fully understood from the following description, illustrated by the accompanying drawings, in which:

Fig. 1 is an elevation of a heating deyice in accordance with the present invent1on, partsof a house heating system being shown diagrammatically in connection therewith;

Fig. 2 is a vertical sectional view through the heating device, partially broken away, showing its interior construction in detail;

Fig. 3 is a horizontal sectional view on the line 3 of Fig. 2;

Fig. 4 shows the heating device of Fig. 1 associated with a vapor separator for use in systems in which a vapor instead of a heated liquid is employed;

Fig. 5 Vis a vertical sectional view through the vapor separator shown in elevation 1n Fig. 4;

Fig. 6 isa horizontal sectional view on line v6 of Fig. 5; and

Figs. 7 and 8 are detailviews, the former in section, illustrating a modified form of construction of the sections of the heating device.

Referring more particularly to Figs. 1 and 3 of the drawings, the numeral 10 indicates the heating device, which is preferably formed of a plurality of units 11 of similar form, mounted upon a base 12 and provided with a top unit 13 to which is connected a flue 28 leading to a suitable stack.

The units or sections 11 may suitably be constructed of cylindrical form. In the construction illustrated, at the upper end of each section, a thickened ring or flange 14 is formed integrally with the wall or casing portion. This flange is formed on the eXterior of the casing and is constructed to provide a. shoulder 15 extending around the entire circumference of the section and into which the lower end of the nextsection above fits. The flanges 14 are of generally lable locking devices.

' of any suitable form, for example, the oil PATENT oFFlcE.

V-section, and provide angular spaces in which a suitable lute may be placed, if desired, or whlch may serve to carry any suit-- Each* seczfion is provided internally with a downwardly inclined baille ring 17, preferably cast integrally with the wall 18 of the section. Above the central opening in this ring is mounted a convex deflector plate 19, which may suitably be supported upon the baille ring 1,7 of the same section by means of the spiral vanes 20. In the construction illustrated, the wall of each section, the bafile ring, the spiral Vanes and the delector plate are formed integrally as asingle casting.

In each. section of the device a plurality of coils 21 of suitable piping are provided above the baille ring and around the opening therein, the ends of these coils being connected near the top of each section to a manifold pipe 22 and near the bottom to a manifold pipe 23. The lowerV turns of the coils vrest upon the spiral vanes 20. The manifolds 22 and 23 may suitably pass through bosses 24 in the wall of the section and the upper manifold 22 of each section is connected with the lower manifold 23 of the next section above by the use of the U-bends 25.

The base section 12 serves as a support for the superposed unit sections 11 and is provided at its upperedge with a ange 26 similar to the anges 14 at the upper edges of each-of the unit sections 11. Withinthe base section 12 is provided a source of heat burner 27. The top section 13 rests upon the shoulder 15 in the flange 14 formed on the upper edge of the next -lowermost section 11 and is of generally inverted conical form, communicating at its to with the Hue 28. The outlet manifold 23 rom the lowermost section 11 communicates with the valved pipe 29 leading into the heating system, which is illustrated as a hot Water house heating system. The upper manifold 22 of the uppermost section 11 is connected with the discharge pipe 30 from the pump 31, the suction side of which is connected with the return pipe 32 from the heating system.

It will be clear from the description and illustration of the construction that the combustion gases from the source of heat in travellingupwardly from the heating device 10, are given a whirling movement by the spiral vanes 20 and are forced by the baille ring's 17 and deflector plates 19 to travel through and around the coils ofpipe 21 through which the heating medium, for cxample, water, flows. The water returning from the heating system through pipe32 is forced by pump 31 through the coils 21, in a direction counter-current to the direction l of travel of the combustion gases from the source of heat. An efiicient heating of the amount of heat necessary for bringing the vheating medium to the temperature required is correspondingly reduced.

` In Fig. 4 the heating medium device 10 is illustrated in connection with a vapor separator which mav be employed when vapor is to be used as a heating medium. The liquid producingthe vapor is 'supplied to the pump 31 from the base of the separator 33, being supplemented when necessary' by additional liquid fed through valved pipe 34. The liquid is forced downwardly throuofh the heating device 10 in the manner just daescribed, passing out from the lowermost section through pipe 29a into the base of the separator 33. Pipe 29a extends to a point above the opening of the pipe leading to the pump as shown more particularly in Fig. 5.

As shown in Figs/5 and 6, the vapor "separator 33 is formed of a plurality' of similar sections 33a, each of which is formed at its upper edge with a flange 35 similar in formto the flanges 14 at the top of each of the sections 11, as previously described. A base unit 36 is provided, this base unitforming a liquid chamber. Into thisunit 36 the pipe 29a from the heating device enters and from this unit the pipe 34a leads to the intake of pump 31.

Each of the sections 33a is provided withV an @upwardly inclined battle ring 37 and a downwardly concaved deflector plate 38 supported above the opening of the baille rings by means of the spiral vanes 39. The bale ring is provided with suitable openings 37a near the wall or casing to permit downward flow of accumulated liquid. In-the base section 36 a deflector plate 38a is provided above the opening of the pipe 29a and is supported by the spiral vanes 39a which are secured to the Side Walls of the sectioni At its top this vapor separator is closed' by a top section 40, the base of which fits into the shoulder of the Hange of the uppermost section 33a. The vapor pipe 41 leading the casin tion illustrated in Fig. 4, the liquid supplying the heating vapor is forced through the heating device 10 by pump 31 in counter-current to the tra-vel of combustion gas therethrough. The more or less completely vaporized liquid passes out through line 29a into separator 33 in which a separation of vapor from liquid is effected. The separated liquid is returned through pipe 34a to the heating device by means of pipe 31, being supplemented by additional liquid through pipe 34. Condensate formed in the heating system returns through the pipe 41 to the separator `and collects in the base of the latter.

In Fig. 7 is shown a' modified form of connection between the manifolds of the successive sections of the heating device. The numerals 11a indicate superimposed sections of the heating device and 21a the coils in each section. The lower manifold 23a of the upper section is bent downwardly, passing through an opening 42Q in the baie ring 17a and connects with the upwardly turne end of the upper manifold 22a in the next lower section, An opening 43 may be provided in each section opposite one of the manifolds `for convenient access to the interior, and may be provided with any suitable closure device 44.
