Specification of Letters Patent. 1
Patented Aug. 1 1, 1908.
Application filed May 8, 1907. Serial No. 371,626.
To all whom it may concern: Be it known that I, ALMERON W. WICK- HAM, a citizen of the United States of America, residing at New Haven, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Heating-Drums, of which the following is a specification.
This invention relates to heating drums designed for the purpose of utilizing the heat from the smoke and gases of combustion from a furnace,- after they have left the furnace, and before they have passed into the smoke stack.
One of the principal objects of the invention is to economize in the use of fuel, and to utilize all of the heat units produced by the fuel, by reventing their escape through the smoke not and out throu h the chimney, before the heat has been ful y utilized.
In .furnaces as at present constructed, the products of combustion are not fully utilized and much of the heat passes up thechimney and is dissipated in the air.
his one of the principal objects of my invention to fully utilize the heat units after and before they are dissipated, through the chimney.
Another object of my invention is to provide simple and efficient means for utilizing the heat of the smoke and gases of combustion by passing the same through a drum or cylinder provlded with a series of smoke leading a quantity of coldair into' the cylinder ata point nearly coincident with the smoke inlet. The
column of air is led in a zigzag coursebetween the smoke flues, impinging on the same, the moving air following alongv the smoke flues, and continuously ascending, while the smoke and gases of combustion continuously ascend wlthin the tubes; the
heated air issuing from. the cylinder at the highest point from the cold air inlet, and at a et which is also at the highest point from the smoke inlet, and thus to utilize the heat radiated from the surface of the flues, for heatpoint nearly coincident with the smoke outlar section on the line 33, Fig. -1. Fig. 4 is a lan view of the ash deflector.
eferring to the drawing for a more particular description of my invention, the numeral 1 designates a horizontally disposed cylinder provided with partitions 2, horizontally disposed flues 3 secured at their ends to the partitions 2 and removable heads 4 at the opposite ends of the cylinder. A smoke inlet pipe 5 communicates with .a smoke chamber 6 and a partition 7 separates the chamber 6 from the chamber 6. Depending from the inlet pipe 5 is as ash clean-out pocket 5 provided with suitable removable receptacles 6 for cleaning out the ashes. An ash deflector 7 comprising a plate provided with apertures 8 and oppositely arranged inclined deflectors 9 extend through the top of the pipe 5 and is provided with extending arms 10* which are designed to be struck by a suitable implement to deposit the ashes which may collect about the deflector into the receptacles 6 A cold air pipe 8 communicates with the cylinder at a point near the smoke inlet pipe 5, said cold air pipe extending downward from the c linder 1. Horizontally disposed deflector p ates 9 extend from the partitions 2 and te'rminate at a short distance from the partition at opposite ends, as shown in Fig. 1. The heated smoke entering the pipe 5 passes the ash deflector through the apertures 8 into the smoke chamber 6, and through the lower flues 3 to the smoke chamber 6 at the opposite end of the cylinder, and from thence passes back through the intermediate series of flues to the smoke chamber 6from which the smoke is led through the upper series of flues to the smoke chamber 6 In the upper series of flues 3 at the end adjacent to the smoke chamber 6 a series of retarders or bushings 6 are provided, these bushings serving to reduce the bore of the flues 3 at the outlet ends to retard the heat and extract all-of the heat units therefrom before it escapes into the chamber 6 and out through the outlet pipe 10.. In the outlet pipe 10 I have provided a'suitable check draft or damper 10. The cold air entering the pipe 8 and the smoke and heated gases entering through the pipe 5 into the chamber 6 are carried in a zigzag course from the bottom lower corner of the cylinder to the diagonally opposite upper corner of the cylinder, the air being heated in its course through the cylinder by the hot air and gases in the flues 3, and the heated air being led-out through the pipe 10 to registers or to be utilized in any suitable manner, while the smoke passes out through the outlet 12.
From the foregoing it will be obvious that a heat economizer made in accordance with my invention will thoroughly utilize the heat from the smoke and gases of combustion before they'pass up through the chimney, and that a material saving in fuel results from this method of treatment.
My invention may be made at comparatively slight cost, occupies but little space, and thoroughly utilizes the heat units which are wasted in the ordinary furnace.
By means of the bushings in the end of the tubes, the area of all the openings therein shall be made no greater than the area of the smoke pipe inlet at bottom of heater, and the gases of combustion are expanded within the tubes to several times their volume at the entrance from the furnace to heater, thus causing a retarding of the flow and imparting heat to the air surrounding and flowing alongside the outside of the tubes.
Having thus described the invention, what I claim'is:
1. A heating drum comprising a horizontal casing having a compartment at each end thereof, a plurality of series of flues communicating at their opposite ends with said compartments, partitions in said compartments, whereby the products of combustion are compelled to take a circuitous path in a zig zag course through the bottom series of flues back through the intermediate series of flues and outward through the upper series of flues, a smoke inlet at one end of the casing, a cold air inlet adjacent to the smoke inlet and a series of deflectors dividing the flues into series and compelling the airlto take'h zlg zag course parallel with the path of movement of theproducts of combustion.
2. A heating drum comprising a horizontal casing having a compartment at each end thereof, a plurality of series of flues communicating at their opposite ends with said com-j partments, partitions in said compartments, whereby the products of combustion are compelled to take a circuitous path in a zig ries of defiectors dividing the flues into series and compelling the air to take a zig zag course parallel with the path of movement of the products of combustion, and retarders for restricting the outlet passages in the outer ends of the upper series of flues.
3. A heating drum comprising a horizontally disposed cylinder, heads within said cylinder, flues extending through said heads, smoke chambers formed outside the heads, partitions in said smoke chambers, deflectors extending in opposite directions in the flue chamber, a smoke inlet pipe, and a cold air inlet pipe located in juxtaposition at the lower corner of the cylinder, and a hot air outlet located at the opposite upper corner from the'inlet pipe.
In testimony whereof, I affix my signature in presence of two witnesses.
ALMERON W. WICKHAM.
