HEAT EXTRACTOR Filed May 6, 1942 .INVENTOR J 1 ATTORNEY Patented m. i
UNITED STATES .PATENT OFFICE 2,343,542 near nxrnac'ron Benjamin n. Faunce, Riverside, N. J.
Application May 6, 1942. Serial No. 441,915
3 Claims. (Cl. 257-165) In my priorpatent, No. 2,070,427, of February,
9, 37, r v"describedand-broadlyclaimed a 19 ha e an air intake 2, the bottom sides and the other novel construction and arrangement of a heat extractor which was found in practice to be emcient in the recovery of heat in the products of combustion passing-from a furnace.
The object of my present invention is to devise a novel heat extractor for the same general pur poses as that of my prior patent, and to construct the device in a novel manner to provide for increased efliciency over the devices of the prior art, to decrease the cost of manufacture and upkeep, to provide for the easy removal of dustand foreign material from the tubes, to provide for the desired humidity ofthe heated air, and toprovide for the automatic control of the source of heat- -for the furn'acein case of abnormal conditions arising in the furnace, or heating system.
With the above and other objects in view as will hereinafter clearly appear, my invention comprehends a novel construction and arrangement of a heat extractor adapted for connection in the pipe line from a heating system.
It further comprehends a novel heat extractor having a novel construction of a casing, novel means for sealing the heating tubes in the ends of the casing, novel means for directing the products of combustion uniformly to superimposed rows of tubes, novel means for filtering the air, and novel means to provide the proper humidity for the heated air.
Other novel features of construction and ad- ,vantage will hereinafter appear in the detailed description and the appended claims.
For the purpose of illustrating the invention, I have shown in the accompanying drawing a typical embodiment thereof which I have found in practice to give satisfactory and reliable results. It is, however, to be understood that this embodimentis typical only, and that the various instrumentalities of which the invention consists can be variously arranged andv organized and the invention is not limited to the exact arrangement and organization of these instrumentalities as herein shown.
Figure 1 is a sectional elevation, partly in full lines, oi. a heat extractor embodying my invention.
Figure 21s an end elevation with certain of the parts removed, and partly broken away.
Figure 3 is a side elevation of a portion of the device.
Figure 4 is a cross section of one of the tubes. Similar numerals of reference indicate corresponding parts.
Referring to the drawingr V l designates a lower casing having at one end end of the casing being closed, and the top being open. A desired number of air filters 3, of spun glass or other suitable material, are disposed within the lower casing, and preferably arranged to provide an inverted V formation through which the air is forced by an impeller 4. 5 is an upper casing secured in any desired manner to the lower casing, and having its bottom open to be in free and unobstructed communication with the chamber of the lower casing. The casings may have any desired contour in cross section, but are preferably rectangular. The upper casing i has closed ends 6 which are apertured to receive tubes 1 which extend through and outwardly beyond the ends and are sealed with the ends by asbestos rings or washers 8, fixed in position by suitable adhesive. I have found that silicate of soda is eilicient in securing the asbestos rings in sealed condition with the tubes and the ends of the upper casing.
The intake end for the products of combustion has a tapered hood 9, terminating in a collar ll adapted to be. connected with the exit or pipe line from a heating system. 'Partitions H at the inner end of the upper casing and within the hood 9 cause the products of combustion to pass to the tubes at diiferent levels to provide a more uniform distribution of products of combustion to the pipes or tubes which are arranged in superimposed rows. The tubes discharge into 1!. ts.- pered hood l2, terminating in a collar I 3 adapted to be connected to the exit pipe line leading to the chimney. The tubes 1 are preferably of copper and at different angular positions along their lengths they are pressed inwardly as at I 4, thus tending to reduce the speed of travel of the hot ases through the pipes or tubes. I have found that the heat absorbed by the air passing around the tubes is materially increased if the exterior surfaces of the tubes have silicate of soda applied to them as a binder, and then have finely divided sand sifted over them to uniformly coat the tubes as shown at I5.
Means are preferably provided to obtain the desired humidity for the heated air. The upper casing 5 has an elongated opening l6 closed by a casing I! having door controlled openings I8 to provide for the insertion or removal of wicks l8. carried by a supporting rod 20 and extending into water in a water pan 2i, partially surrounding one of the tubes. The water is fed to the pan from a supply tank 22, provided with a conventional float save Witter: its
pan at a desired level. 23 are exit pipes from the casing H to conduct heated air to a desired place of utilization.
- The heat extractor is connected'in a pipe line 24, forming the exit from a'fumace of any con,- ventional construction. As illustrated, I provide at the intake end of the extractor a valve casing 25 having an outlet 26 leading to the intake end of the extractor and having an outlet 21 leadin to a by-pass 28. A manually actuated valve 2!- ,controls the outlets so that when the .wicks are to be changed or cleaned the gases can. be by.
passed through the by-pass. The bottom of the valve casing has an opening 30, controlled by a counterweighted safety valve 3|, which, in case of an explosion in the furnace, will closethe circult through a contact 32 of a solenoid circuit 33 to cause the solenoid to open a switch controlling the fuel and air supply to the oil bumer or other type of source of heat for theiumace. The possibility offire from the gases is reduced by pass-, ing the-products ofcornllustion through a number of tubes. air will still pass into the furnace, and be heated by the hot walls of the furnace for sometime. If the heating system is not in use, the impeller can I be operated during such period to circulateconpered hood connecting the intake end of the upper casing with an exit from a furnace, a tapered hood connecting the exit end of the upper cas- 7 ing with a pipe line leading to the chimney, and
pipe connections for delivery of heated air from the upper casing.
2. In a heat extractor as set forth in claim 1, having an addition means to bypass the products of combustion from the intake pipe from the rurnace-to the pipe leading to the furnace.
