Application filed anuary 21, 1913. Serial No. 743,295.

To all whom it may concern:

Be itl known that I,.JUL1US H. Bannion, a citizen of the United States, residing iii the city and county of San Francisco and State of California, have invented new and useful Improvements in Liquid-Ifiydrocarbon Furnaces, of which the followingl is a specification.

This invention relates to an auxiliary furnace especially constructed to handle-liquidhydrocsirhons, such as crude or fuel oils,

The niaiii object of this invention is to provide a simple, substantial and durable furnace of the auxiliary type, wherein high temperatures' may loe generated without eX- eessively exposing any particular part .of the furnace.

Another object of this invention is to provide outside'nieaus for supporting the main arch of the furnace so as to eliminate the use of any inside supports which would sooner or later deteriorate by constant exposure to the heat in the furnace .and leave the arch in a weakened condition, when it would finally collapse, a further object being to so arrange the draftcontrols and flues of the furnace, that the products of combustion generated in the front half of n the furnace may be conveyed to the point of discharge without disturbingl the Haine area of the rear part of the furnace.-

The invention consists of the parts and the construction and combination of parts as hereinafter more fully .described and claimed, havingr reference to the accompanying drawings, in which:

Figure l is a longitudinal section on the line X-#X of Fig. 3. Fig. 2 is a cross section on the line V-*V of Fig', 3. Fig. 3 is a plan section on the line YY of Fig. l.

Fig. 4 is a perspective View showing' the firing plate support or hase. Eig. -5 is a plan showing the draft regulating means controlling admission of draft through the central opening.

Referring to tlie'drawi'ngs A indicates the shell of a furnace which may -he constructed of any 'suitable refractory material, such as fire brick or the like, and which may be inclosed by a suitable metal framework lor casing, as at 2.

3 indicates the central or main-cornbus tion chamber of the furnace,l in the lower and lcenter portion of which is mounted an atomizing org-,firing plate 4, to which a suit ahle liquid-liydrocarhon fuel, such as crude oil, is delivered through a central opening 5 formed in the top portion 6, or arch of the furnace.

9 indicates a water supply pipe controlled hy a valve i0, and 7 the oil conveyin pipe controlled hy a valve 8; the pipes and 9 meeting in a delivery pipe il., the discharge tip 12 of which lies just above the open top of the central opening 5.

Leading from the exterior' of the shell and controlled by a door 13 is a passage 14, formed in the hase of the sheli, which opens interior-ly under the plate 4; the plate being so positioned as to forni a roof or covering, for the passage. The inner opening or throat of this passage is slightly enlarged to receive a rectangularly shaped hollow metal base 15, which is provided for the purpose of sup: citing the generating or tiring plate.

rilhe 'tiring plate 4c and hase should pref# erahly be made of cast steel or like material, which will he able to stand the high-tern peratures of the furnace without cracking' or bending out of shape; this being of great importance when one considers that any slight bending or warping of theloase and plate might cause an uneven flow or discharge from the plate. with a consequent inequality. ot flame distribution. The size of the hase and plate are such that they may he removed through a door i6 closing an opening 17 formed in the front part of the furnace'.

` For the purpose of producing a perfect and uniform combustion in the furnace, and aise for thepurpose of eonveving the prodn nets of combustion generated inthe front .hait of the furnace to the point of dis` charge. indicated at 18, without interfering with the flame area in the rear half oi" the coiiihustion chamber. lt have shown the furnace as being' provided with two side `lilies 19 and Q0 through which the products in the front halt' of the furnace niay he con veyed'as indicated by the arrows, to the point of discharge without disturbing the Haine area of the rear half oi" the `furnace. The rear portion of the combustion-chamber is also provided with a discharge opening, indicated at 21, of a suiiicient restricted area to balance or equalize the dischare of the products of combustion through the difterent fines arch over 'the combustion chamber, I have provided the head blocks 22.. and a suitable Vnumber of tie-rods 23; the head blocks being;` suitably supported in the metal frame or casing, inclosing the furnace. This construction Aentirely eliminates the necessity of providing inside supports, which would sooner or later deteriorate by constant er#` posure to the heat Within the furnace, and thereby leave the arch in a Weairened condition so that it would nally collapse. it can front half of the com therefore be seen that the Walls 24 and 24s separating the side fines, 19 and 20 from the main combustion chamber, may be entirely destroyed Without weakening the main arch,

In operation, a temporary fire is made from any suitable fuel placed in the pas sage le, below the generator plateall draft openings except the'door 13 being closed. This lire is continued until the .plate 4 is sufficiently heated to vaporise the water and oil when delivered to the plate. The oil and Water in the right proportions are then gradually turned'on, and are ignited by the llames discharging around the plate l from the lower preliminary heating chamber le;

the :base portion 15 being formed with escape passages l5n for this purpose. The moment sufficient heat has been generated Within the main combustion chamber to support co1nbustion, Within the temporary heatingy chamber le may be drawn and the door 13 closed. .'Slie main draft necessary for comn bustion is then admittedwith the falling fuel mixture through the central opening 5; this draf-t being regulated by a pair of plates 25, slidahly mounted in a suitable metal traine i 26 mounted in the upper end of the central opening. The fall of the mixed oil and Water from the tip l2 to the plate 4t is Sudicient to cause it to spatter and atomize. ihc

mixture is this evenly spread over the plate and burns with a dame which spreads evenly to all sides of the combustion chamber; the products of combustion generated in the ci the furnace being carried by the drsitthrough the side 19 and 20, from .Jhich they are. conveyed to the main disch pas. i8, Where they unite with the products o combustion from 'the rear stion chamber, which are disch ng through the restricted opening 2l; :i opening being sinhciently re stricted, as before desc iced, 'to cause an equal 1ibrtim fi f through the ial in con-- motion, eiiicient end 'reliable inaction, and
