1 Claim.
This invention relates to means for heating water; for kitchen use as Well as for room heating purposes.
The principal object of this invention is the provisionv of heating means of the character described which maybe used in conventional coal and oil burning furnaces. It comprises an attachment which may be mounted inside of the furnace and which may be connected to the water. jacket thereof. It is also connected to the hot water tank of the system in, addition to the connections which are conventionally provided between the water, jacket of the furnace and the hot water tank. The water heating means under discussion is really auxiliary to the conventional water heating means with which furnaces are provided, but the heating capacity of this auxiliary means .may exceed the heating capacityof the conventional water heating system.
Anotherobject of this invention is theprovision of 'awater heating tank which is positionedwithin conventional furnaces withits bottom at a. level below the top level of the burning coal. When used in connection with, oil burning furnaces,
this water heating tank is situated so that the flames actually make contact with'it.
Another object of this inventionis vtheprovision of a water heating means auxiliary to the water heating system of conventional furnaces, said auxiliary Water heating means taking the form of a smoke pipewhich connects the furnace to the chimney, said smoke pipe having a sinuous form and extending through the-hot water tank of the system.
further object of this invention is the provisionof additional means for heating the water, said additional means comprising a compound pipe, that is one pipe within another, the inside pipe being the water pipe and the outside pipe being the smoke pipe whereby the hot gases that 'fordinarily escape throughthe chimney may be utilized toheat the water.
Preferred embodiments. of this invention are shown on the accompanying-drawing in which:
heating elementshown in Fig. lwhichis mounted within the coal burning furnace; and
Fig. 3 is a perspective View ofasecond .formof this invention.
Referring to Fig. 1 itwill be seen that a conventional coal burning furnace I0 is provided with a. water jacket ll communicating throu h pipes l2 and I 3 with a hot water tank M; The pipe l2 leads water from the furnace to .the tank M. The water in the tank Mcan be recirculated by means of the pipe. [3' (see upper left hand corner of Fig. 1) which leads back to the. water jacket ll. Thus far a conventional installation has been described. It will be noted that two auxiliary hot water tanks 28 and 2.], respectively, are mounted in the combustion chamber of .furnace I0 and that their lower ends extendjinto the burning coal 23. Theyare supportedin the furnace by meansofbrackets 24 and 25, respectively. Pipes '2'! and 28 provide communication between these two tanks, and pipes. 29 and .30 provide communication between tank; Zlland' the water jacket H of. the furnace. .Another .pipe..3';2 provides communication between. tank 20. and conventional hot water tank I4 above mentioned.
It :will be notedthat. a .smoke pipe or .fiue- 40 carries 01f the hot gases from the combustion chamber of furnace l0 and directs them into thechimney .(notshown'). This pipe 40 is provided, with several bends or curves which gives it a sinuous form. These bends are formed. in the pipe outside of tank l4 as-well as inside ,of the tank. It will be noted that the bends inside of tank [4 are directed fromside to side and not upwardly. and downwardly. The bends inside of the tank aremore clearly shown inFig. 3. The essential difference between the bends in Fig. l and those shown in Fig. 3 is the fact that the bends in Fig. 1 alllie on a common horizontal plane inside'of the tank-whereas the bends in Fig. 3' slope upwardly. Actually the bends in Fig. 3 extend from side to side but always ona sloping p'lanewhich extends upwardly from the-inlet end of the tank to the outlet end. On the other hand, thebends outside of tank l4 extendboth vertically and horizontally. In no case, however, do thebends-outside of tank [4 slopedownwardly as-viewedfrom the inlet end'to the outlet end of the bends outside of the tank. The principle underlying the fact that none of the bends carry the pipe downwardly. as viewed from the inlet end to the outlet end of the pipes in question, is the requirement that at all times the smoke be made to travel upwardly or at least on a horizontal line but certainly not downwardly.
.pipe 40 is shown in Fig. 1 to be provided.
It will be seen that pipe 32 which provides communication between tanks 20 and I4 extends through smoke pipe 48. It is apparent that bends corresponding to the bends in pipe 4!! are formed in pipe 32.
From the foregoing it will be understood that when the furnace I is in operation, the tanks 20 and 2| will be exposed to the direct heat of the burning coal. The water in these tanks will very quickly be heated to a high temperature and the heated water will tend to flow upwardly through pipe 32 and into tank l4. The return flow will pass through pipe l2 into the water jacket I of the furnace and thence through pipe,
39 into tanks 20 and 2|. To a limited extent the circulatory system thus described will be short circuited by a return flow of the water in tanks 20 and 2| to the water jacket through pipe 29. The bends in smoke pipe 40 will cause the hot combustion gases to enter into intimate contact with the pipe 32 which extends through said pipe 40. These gases will contribute to the process of heating the water in pipe 32. The bends 01' curves in pipe 40 which are formed inside of tank i4 provide a greater surface area of contact between said pipe and the water in tank I4 thereby giving the hot combustion gases in said pipe a greater opportunity to yield their heat through the pipe walls to the water in said tank I4.
The second embodiment of this invention is similar to the first embodiment in that a bent smoke pipe 50 extends through the Water tank It is also similar in that a hot water pipe 52 corresponding to the hot water pipe 32 extends through pipe 59 and leaves that pipe inside tank 5| adjacent the inlet end of said tank. Pipe 52 is therefore in direct communication between the water heater 55 and the inside of the water tank 5|. The furnace 56 is also a conventional furnace, but its smoke outlet rises continuously in passing from the furnace to the hot water tank and extends in sinuous orientation generally horizontally there-of rather than gen-- .erally vertically as is the case with the furnace shown in Fig. 1. Pipe 59, however, is provided with substantially the same number of bends as It will be noted that the bends in pipe 50'inside of tank 5| lie on a plane which slopes upwardly from the inlet end ofthe tank to the outlet end. In other words, a sectional view of tank 5| would appear similar to tank M in Fig. 1, except that sinuous pipe 59 would have its right end lower and its left end higher than pipe 4|] in tank M of Fig. 1.. Aside from this slope the bends in pipe 50 inside of water tank 5| extend from side to side rather than upwardly and downwardly.
Another difference between the embodiment under discussion and the first described embodiment resides in the means of fastening their respective water heaters to the inside of their respective furnaces, in Fig. 2 horizontally extend- The number of bends in pipe 40 as it extends through tank I4 is not critical. A greater or lesser number of bends than shown may be used as and when desired.
The auxiliary heating means consisting of tanks 20 and 2|, pipe 32 extending through bent smoke pipe 40 and the bent portion of pipe 49 which extends through tank M, has above been described in connection with a hot water tank generally used to supply the household kitchen and bathroom with hot water. It will be appreciated that the same system may be used in connection with the steam heating system of the home or with its hot water heating system, wherever it may happen to be installed in a particular house. The hot water tank shown in the drawing is preferably lined with porcelain or a similar vitreous material but other types of hot water tank may also be used.
I claim: 1
In a furnace having a water jacket, a combustion chamber, and a separate hot water tank connected thereto, the combination of an auxiliary water tank mounted in the combustion chamber, a smoke stack from the furnace extending through the hot water tank, and a water pipe extending from the auxiliary tank in the furnace and disposed within and along said smoke stack and connected to the interior of the hot water tank, said smoke stack where it is outside of the hot' water tank being sinuous in form and rising continuouslyv in passing from the furnace to the hot water tank, and said water pipe within the smoke stack having its sinuous axis coincident throughout with that of the smoke stack.
