Our invention relates to heating systems for' buildings, and more particularly to an improved iiue or chimney forming part of such heating systems.
Heretofore it has been the practice to construct the ue or chimney Aof massive masonry.'
The thick walls of the chimney were necessary in order to provide sucient heat insulation and the chimney necessarily had a large heat accumulating capacity, and the heat absorbed was lost* to a great extent.
In accordance with our invention the iiue is constructed of a number of metallic 'pipe sections of convenient length. Each section is surrounded by a Water jacket in the form of a shell welded or otherwise suitably secured to the section or conduit forming'the iiue. Jackets on adjacent sections are connected together by means of one or more pipes which are preferably made of flexible material such as copper, to thereby permit a slight relative movement which results from expansion and contraction due to temperature changes. The Water heated in these jackets may be utilized to heat the building and thus, in accordance with our invention, not only is the size of the chimney reduced, but the heat absorbedv thereby is utilized.
A further advantage of our invention is that the ue may-be installed after the building has been erected.
Further objects and advantages of our invention will be apparent from the following description considered in connection with the accompanying drawings which form a part of this specification and of which:
Fig. 1 is a cross-sectional view of one embodiment of our invention;
Figs. 2, 3 and 4 are cross-sectional views on a larger scale showing portions of the device illustrated in Fig. 1;
Fig. 5 is a cross-sectional view of another embodiment of our invention and is taken on the line 5-5 of Fig. 6;
Fig. 6 is a cross-sectional view` taken on the line 6-6 of Fig. 5;
Fig. 7 is a cross-sectional View on an enlarged scale of a portion of the device shown in Fig. 6;
Fig. 8 is a cross-sectional view taken on the line 8-8 of Fig. 7;
Fig. 9 is a cross-sectional view taken on the line 9--9 of Fig. 6.
Referring more particularly to Figs. l through 4, reference character l0 designates generally a building having a cellar II, a first story I2, a second story I3 and an attic I4 covered by a roof I5. Located in the cellar II is a furnace,
'designated generally by reference character I8.
Furnace I6 includes an inner shell Il defining a combustion chamber and an outer shell I8 form'- ing a water jacket around the furnace. A conduit I9 communicates with the combustion chamber and extends through the water jacket to the exterior of the shell I8.
Connected together and to the conduit I9 is a plurality of nue sections designated generally by reference characters 20 and 20a. Each of these sections includes an inner conduit 2| to which is secured a jacket 22. The ends of the conduits 2| extend beyond the jackets 22 in order to provide means for coupling the adjacent sections together. Section 20a differs from the sections 20 in that the jacket 22a is of greater diameter than the jackets 22 and the pipe coil 23 is disposed -within the annular space formed within the jacket 22a. As will be clear from Figs. 2, 3 or 4, the lower ends of the conduits ZI are formed with bell mouths 24 of a diameter suitable to receive the upper ends of adjacent conduits 2|, or the upper end of conduit I9. In the places where the sections extend through the floors 25 of the building they are supported by means of brackets 26, welded or otherwise suitably secured to the outside ofjjackets 22. Thus, most of the sections are independently supported and expansion and contraction thereof due to changes in temperature is made possible by a slight slippage 'of the conduits 2I within the bell mouths 24. Adjacent water jackets are connected together by means of one or more conduits 21, each conduit being preferably providedwith a valve 28. These conduits are made of a flexible material such as copper in order to permit the aforesaid expansion and contraction of the flue sections.
On the rst floor of the building there is shown a cooking stove 3B connected to the iiue by means of avconduit 3I passing through the jacket 22a.
A damper 32 is located in the flue just below the point of connection of conduit 3|.
The upper end of coil 23 is connected to a water supply pipe 33 and the lower end of the coil is connected to a pipe 34 which supplies hot water for use in the building.
The upper end of the uppermost section 24, which terminates within the attic I4. is connected Y to a double Walled conduit 35 which extends through the roof. The space between the walls of this conduit may be lled with any suitable heating insulating material, but a small amount of insulation is suflcient due to the fact that the ilue gases at this point have a comparatively low temperature.
A conduit 38 is connected to the upper part of the uppermost jacket 23 and leads to one or more hot water radiators 31 located in the building. An expansion tank 38 is connected to conduit 38 and is provided with overflow conduit 33 extending through the roof I5. Valves 40 are provided between conduit 36 and the inlets of the radiators 31. Conduit II connects the outlets of the radiators with the lower part of the jacket I8 s urrounding the furnace. A conduit 42 provided with a valve 43 connects the lower part of conduit 36 with the jacket 22a. The lower end of conduit 38 is connected to return lconduit 4I through a valve M.
The operation of the above described device is as follows:
The products of combustion formed in the furnace I6 pass through the conduit I3 and the conduit 2l of the different sections 28 and 20a and are discharged to the atmosphere through the conduit 35, which extends through the roof. The jacket I8 around the furnace and the jackets 22 and 22a forming part of the ue sections 28 and 28a are filled with water, the valve 28 in the conduits 21 between the jackets being open. This water is thus heated by the flue gases and tends to rise due to the lowering of its specific gravity. The heated water passes through the conduit 38 and through any of the radiators 31 the valves 48 of which are open. From the radiators the Water passes through the return conduit 4I to the jacket I8, where it is again heated and ascends through this jacket and through the jackets and 28a. In the event that all of the valves l0 are closed, thermal circulation through the jackets and the conduit 36 may nevertheless take place due to the fact that valve Il is open,
thus connecting conduit 36 with return conduit 4I.
The products of combustion produced in stove pass through conduit 3I to the ilue. The water passing through the coil 23 is thus heated by the products of combustion from both the furnace and the stove. It will be noted that the Water passing through coil 23 ilows counter-current to the -ue gases within the flue. y As previously stated, the water heated in coil 23 constitutes the hot water supply for the building.
In. the event that it is not desired to use the furnace, as in the summertime, the valves 28 in the conduit connecting the jacket 22a. with the jacket 22 immediately therebelow are closed, as is the valve 44, and the valves of the radiators. If desired,` the jackets I8 of the furnace and the jacket 22 immediately thereabove may be drained.
Under these conditions, the coil 23 is heated` solely by the flue gases discharged from the stove 30. Valve 43 is open'and thus thermo circulation may take place upwardly through the jackets 20a and 28 and downwardly through the conduits 36 and 42.
Hence, under all conditions, the conduits 2I which convey the hot ilue gases are surrounded by a circulating layer of water which prevents the transmission of excessive amounts of h eat to the building. Inasmuch as a circulating layer aaomoo` rounded by a conduit 80 of. suitable material, such as sheet metal or ilber board, forming an annular passage 8| around the jackets 22 and 22a. 'I'he upper end of passageway 8| is connected to a space 83 formed between conical plates 84 and 88. Pipes 88 lead from the space 83 and open into the upper parts of the rooms on the second story of the building,l preferably in the neighborhood of the windows. A return 'air duct 81 communicates with the lower parts of these rooms and extends downwardly to an air chamber 88 in heat exchange Arelationship with the stove or furnace 83. This air chamber is connected to the lower end of the passage 8| surrounding the ilue sections. 'I'he rooms on the lower door of the house are heated by air conducted through passages 88, which are branched oit from the passage 5I, to the upper parts of therooms. Return ducts 8I lead from the lower parts of these rooms to the chamber 58. A certain percentage of fresh air from outside the building is supplied through the duct 62.
As shown in Fig. 9 the passage 5I may be divided into a plurality of passages by means of partitions 83 whereby the air circulated to and vfrom the diil'erent rooms may be kept separate.
For this purpose, the chamber 58 which is in heat exchange relation with the furnace or stove 83 may likewise be divided into a plurality of passages by means of partitions 84. As shown in Fig. 6, one o1' the passages defined by partition 63 may be in communication with the lower part of a room through an opening 85 and with the upper part of the same room by an opening 88, the air heated within the passage rising and passing through the opening 88 into the room, where it is cooled and falls to the lower part, of the room and then enters the passage through the opening 65. If desired, fins, corrugations or other means for increasing the surface of the water jackets may be employed, as is shown at 61 in Fig. 9.
1 or less specic embodiments of our invention, it
of water having the same insulating capacity as a masonry chimney is much thinner than the latter, a considerable amount of space in the building is saved.
In the embodiment shown in Figs. 5 through 9 the building is heated directly by air. For this purpose the flue sections 28 and 28al are sur- As shown in Figs. 6 and '7, a water reservoir 88 is provided in heat exchange relation with the stove or furnace and communicates with the lower end of passage 5I, whereupon vapor generated by the heating of the water in reservoir 88 passes into the air flowing through passage 8|, thus increasing its humidity, as is desirable in the winter.
As is shown in Fig. 7, the wall of the jacket 28a, within which is located the heatingl coil 23, may be corrugated. This not only increases the heat transfer area of the jacket, but also tends to 0 create a more or less circular ow of water within the jacket, which improves the heat transfer between the water and the pipe coil.
While we have shown and described two more is to be understood that this has been done for purposes of illustration only and is not to be considered as limiting the scope of the invention, which is to be' determined by the appended claims.
