The invention has am 5 to provide a turna atente @et i5, 1935 aorzais rr. uname APPARATUS Okla., assgnor to The Tulsa, Okla., a
corporation of Delaware application March 2s, 193s, serial No. 663,179 9 Gleims. (Cl. ll22 356) ong its general objects ce wherein uid-handling tubes may be subjected from opposite sides to radiant heat and withal wherein other fluid-handling tubes may be heated by combined radi and still other. tubes by Other more detail objects will more freely appear hereinafter.
Generally speaking the vides a walled nace chamber w of combustion cha taining chambers, dividing Walls adap structure descence by the hot gases bustion chambers heated from opposite sid bank of fluid handling tubes above the combuswhereby to provide a furnace ant and convected heat convected heat alone.
present invention proiorming a closed furherein are provided a plurality mbers separated by tube-conthe chambers having common ted to be heated to incangenerated in the comthe tubes will be es by radiant heat; a
tion and tube-containing chambers, respectively, and preferably also a bank of tubes adapted to be heated by the spent heating main furnace chamber.
The various features of will more fully appear tion taken in co drawings forming part o wherein- Fig. 1 is a vertica a furnace embodying present invention;
Fig. 2 is a horizont in Fig. 1;
Fig. 5 is a parti modied form of tubes;
Fig. 6 is a certain banks.
As shown in the gases leaving the novelty and invention from the detailed descripnnection with the l accompanying f this specincation and l longitudinal section through the general features of the al section on. line 2-2 of Fig. 3 is a vertical transverse sectionlon line Fig. 4 is a side elevation of the furnace shown al section in plan showing a connection between certain perspective diagrammatic view r showing the banks of tubes as connected up in slightly differenty mann Figs. l and 2, and
Fig. 'I shows a er from that shown in modied form of hook-up of drawings there is provided a walled structure forming a closed furnace chamber, the roo Fig. 1, the
f of which il, the side walls at l2 I3 and |31.
is indicated at I0, and the end chamber is divided by an upstanding bridge wall it thus forming chamber sections A and B. Section A is of course the main furnace chamber. Rising from the iloor of chamber A are a series of upstanding refractory walls il forming a succession of compartments 5 l5 and I6. These Walls preferably extend the full width of the chamber; 4terminate a substantial distance below the roof IU; may be and preferably are multi-apertured as indicated at i8 and are supported on pedestals IS. Any suitable 10 means not shown may be employed for bracing the walls against lateral deflection.
Compartments i6 constitute combustion chambers wherein fuel delivered by any suitable burners generally indicated at 2@ is burned. The 15 kind of fuel used is immaterial but will ordinarily be oil or gas. The burners preferablyre from opposite ends of the respective combustion chambers and there may be a vertical series of such burners for each chamber. For illustrative 20 purposes, only one burner at each end of each combustion chamber is shown.
The hot gases generated in the combustion chambers now upwardly between the walls il! forming such chambers and into the space im- 25 mediately below the roof it) of the closed cham- `ber, thence` over the bridge wall l land downwardly through chamber B on their way to the opening 2| leading to the stack, not shown.
Mounted in chamber B is a bank of tubes C, 30 the bank being heated by the outgoing gases of combustion as will be readily understood and hence may be termed a convection bank. The lower and upper terminals of this bank dicated at 22 and 23, respectively, derstood that the tubes are serially connected. As shown these tubes extend through the side walls i2 of the closed chamber and at their outer ends are serially connected by removable return bends. 40 In the space immediately below the roof I0 is provided a bank of tubes F which may extend lengthwise or crosswise of the roof. As shown through the side and at their outer -ends kare connected by removable return bends.
ism, are of considerable height I5. The danger and the separating the respective chambers will be heated to incandescence with the result that the tubes comprising the respective banks D will be heated by radiant heat fromopposite sides. This is an important feature of the invention and quite apart from other features marks a decided improvement in the art of oil-heating furnaces.
Due to the fact that the Walls I1 are in paralleland open into a space below the roof I0 of the closed chamber, there is produced a chimney effect tending to cause the gases of combustion to flow directly upward rather than laterally through the apertures I8, even though the individual apertures may be of substantial cross sectional area. These apertures may be termed radiant gaps since they permit heat from the flames to be radiated directly into the heating chambers I5. Such gases of combustion as may flow through the apertures are not objectionable but rather set up a desirable circulating effect in the heating chambers. apertures also permit more uniform and rapid heating of the walls I1.
In the space between the bridge wall I4 and the adjacent radiant walls I1 is a bank oi' tubes D1 corresponding to the'banks D and in the space betweenthe end wall I3 of the closed vchamber and the adjacent radiant wall I1 is a bank of tubes E also corresponding to the banks D but being of greater height for connection with the roof 'bank F.
Banks D, D1 and E together make up what I term a radiant bank since heating thereof is primarily by radiation from -the radiant walls I1. Bank C is of course heated solely by convection whereas bank heated partly by convection and partly by radiant heat.
As shown in Figs. 1 and 6' the banks c, D1, D, E v and F are in series connection in the order named.
in Fig. 6 or in the reverse order as shown in Fig. i depending upon the particular oil processing method used. In Fig. 1, pump P is shown as coupled to terminal 21 of bank F for forcing the oil iirst through that bank and then through the other banks as will be readily understood whereas in Fig. 6 pump P1 is shown as delivering directly to bank C.
In Figs. l, 2 'and 4, those tubes of banks D, Dl and E that are in a common level are shown as connected in series by pipes 24 with the various levels connected in series. However in so far as the present invention is concerned it is immaterial whether the said tubes be connected in that manner or in some other manner. 'I'hus as shown in Fig. 6 the tubes comprising such individual banks may be connected in vertical series various banks connected in series. In Fig. 6, reference characters AD, AD1 and AE correspond to reference characters D, D1 and E. respectively, in the other gures.
Instead of connecting the tubes of the radiant banks by pipes 24 which are wholly outside of the closed chamber as shown in Fig. 2, they may be connected as shown in Fig. 5. That is to say, the adjacent tubes D in a common level may be connected by a pipe 24 so formed as to extend back into the chambers I5 and then alongside of the inner side of wall I2 and through the combustion chamber I6 that separates the heating chambers of overheating such connecting pipes 24' is reduced to a minimum since they are located in close proximity to the outer walls I2 of the closed chamber.
`and C2 are located in chamber B1.
relatively cool Since the tubes comprising the various banks extendthrough the opposite side Walls I2 of the closed chamber they may be readily cleaned and nections at the outer ends of the tubes being re- 5 will be heated partly by radiation from the adjacent radiant wall I1 and partly by downgoing gases of combustion. Within the chamber Bl thus formed by the bridge wall |41 is an upstand- 15 ing bridge wall I 4, the outlet from the chamber being indicated at 2I. Two banks of tubes C1 Bank C1 is shown in series connection with bank F and bank D2 with bank C2. With this hook up the course of .20 the oil would be first through convection bank Cl, thence through roof bank F, thence through-the next succeeding banks between banks F and D2., and finally through banks D2 and C2. P2 indicates a pump for circulating the oil in the manner 25 just described.
While I have shown and described a number o1' different hook-ups that may be used nevertheless it will be understood that the present invention is primarily concerned not so much with any par- 30 ticular hook-up as with a furnace that is readily adapted' for such hook-ups or in other words with a furnace construction as particularly set forth in the appended claims.
