AIR-HEATING APPARATUS.
Specification of Letters Patent.
Patented Nov. 30, 1920.
Original application filed September 8, 1914, Serial No. 860,709. Divided and application filed March 13, 1917, Serial No. 154,588. Divided and this application led May 5, 1919. Serial No. 294,815.
To all whom z5 may concer/n.'
Be it known that I, MAX SKLovsKY, a citizen of the United States, and a resident of Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Air-Heating .-ipparatus, of which the following is a specification, reference being had to the accompanying drawings.
lt y invention has to do with air heating devices and has particularly for its object to provide an improved apparatus suitable for use in connection with liquid fuel burning furnaces to heat the air mixed with the liquid fuel to produce a combustible mixture, although it should be understood that my improved apparatus may be applied to any other use for which it is suitable. My improvement consists in providing a sectional heater the sections of which are provided with internal passages or tlues through which the air to Vbe heated is conducted in series while it is exposed to heated gases flowing through tortuous or staggered eX- ternal passages provided through the several sections. A feature of my invention is that the sections are all alike and are so constructed that a unit composed of a number of sections may be built up by merely turning adjoining sections end for end and securing them together, with the result that the series connection of flues isestablished.
Thus units of any desired size may be built up without the necessity of selecting sections of different design. I accomplish my object as illustrated in the accompanying drawings and as hereinafter more particularly described.
In the accompanying drawings in which I have illustrated my improved air heating apparatus as applied to a metallurgical furnace similar to that Shown and described in my pending application for patent for apparatus for producing and consuming gaseous fuel, filed March 13, 1917, Serial No. 154,588, as a division of my application which matured into Letters Patent No. 1,229,338, granted June 12, 1917, for method of producing fuel gas,-
Figure l is a view of a heating furnace having my improved air heating apparatus applied thereto;
Fig. 2 is a vertical cross-section through the apparatus shown in Fig. l; and
Fig. 3 is an enlarged vertical section on line 3-3of Fig. 2.
Referring to the several figures of the` drawings,-A represents the combined combustion and heating chamber of an ordinary heating furnace suoli as is employed for certain metallurgical operations. B indicates the walls thereof, preferably of brick, as usual. (l indicates the usual opening in the front wall of the furnace through which are y `device or heating chamber composed of a plurality of chamber sections F, F, F, placed one over another', as shown in Figs. l, 2 and 3; A"ill of these heating chamber sections are alike in construction, each being provided with a plurality of flues F so disposed that by turningadjoining sections end for end in assembling them the flues of adjoining sections will be staggered with relation to each-other and the spaces between the iues of the several sections will form open tortuous passages for the escaping gases., `thereby better utilizing the waste heat to effectively heat the walls of the several sectionsF, as clearly shown in Fig. 3. This provides a very cenvenient construe` tion, as all the chamber sections are made off the same pattern. .ilie several sections F are secured together so as to be readilyremovable, thereby ,permitting any desired number to be used, for it will be understood that while three sections are shown in the construction illustrated, the number may be varied to suit different sizes of furnaces. In the construction shown, the several sections are secured together by bolts F shown in Fig. 3. The several sections are each provided with an air inlet and an airy outlet, as also shown in Fig. 3, the inlet and outlet passages being at the opposite ends of the section, and the sections are connected in series so that the entering air traverses the several sections successively from end to end and thereby permits all the air that passes through the device to attain a substantially uniform temperature. This is an important consideration as in order that the apparatus may operate to the best advantage, the air must be uniformly heated so that When it comes in contact with the vaporized fuel oil there Will he no danger of premature ignition.
Gr indicates a pipe through which air is admitted to the sections F, it opening,- as shown, into ine upper one of such series of sections. T he air so supplied is forced through thc pipe under pressure by any suitable moans (not shown), and receives heat by conduction through the Walls of the heating cha iber, as will be understood. H indicates a valve in the pipe G, by means of which the quantity of air passing through the pipe can be regulated or the supply shut off entirely.
JA indicates a pipe connected to and opening into the lower heating chamber section F and passing` through a suitable opening in the wall of the furnace Where it is so connected to a vaporizing chamber K, as to deliver the heated air from the chamber sections F to the upper part of such vaporizing chamber, Also communicating with such vaporizing chamber K, near the upper end thereof is another pipe, indicated by M, of very considerably less diameter than the airconducting pipes (if and J, which pipe M is for conducting the fuel oil employed to the said vaporizing chamber K. N is a valve for controlling the flow of oil through the pipe. it its lower end the vaporizer K communicat-es with the 'combustion chamber A through a pipe connection L that passes through a suitable opening D in the `Wall of .the furnace into the combustion chamber.
trative as my improved heating apparatus may be applied to other forms of furnace or may be used for any other purpose for which it is adapted.
lVhat l claim as my invention and desire to secure by Letters Patent, is-
l. An air heating chamber comprising a plurality of similar `chamber sections tted together and having iues communicating with one another, adjoining sections being turned end for end, each section having open passages therethrough, the passages of adjoining sections eing staggered with relation to each other, and means for securing the sections together.
2. An air heating device comprising a plurality of chamber sections fitted together, each having a plurality of iiues therethrough, and open passages around said fines, the tlues of said sections being connected in series, and means detachably securing said sections together'.
3. An air heating device comprising a plurality of similar chamber sections, each having a plurality of vllues therethrough and open passages around said flues, said tlues and passages being arranged so that When said sections are fitted together with adjoining sections turned end, for end the flues ofA adjoining sections will he staggered With relation to each other, providing tortuous passages through the assembled sections, and means for securing the sections together.
et. An air heating device comprising a piurality of chamber sections fitted together, each having a flue therethrough, the end portions of the iues of said sections being connected in series, open passages through said sections around said iues, and means for securing said sections together.
5. An air heating device comprising a plu` rality of chamber sections itted together, each having a flue therethrough, the end portions of the dues of said sections being con-z `neet-ed in series, open passages through said sections around said tiues, the passages of one section being in staggered relation with those of an adjoining section, and means for securing said sections together.
