Specification of Letters Patent. Patented June 20, 1922.

Application filed June 19, 1918, Serial No. 240,732. Renewed April 8, 1922. Serial No. 550,792.

To all whom it may concern:

Be it known that I, CHARLES D. Mosrrnn, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Oil Burning Apparatus, of which the following is a specification, reference being bad therein to the accompanying drawing.

My invention relates to improvements in gasi" *ing and ,atomizing fuel and has particular reference to an apparatus'for preheating a liquid fuel such as hydrocarbon oil and then atomizing the same by means of the oil vapors or gas which are preferably created by the use of steam coils in the oil and gas chambers.

In the accompanying drawings, I have illustrated in Fig. 1 in side elevation, a suitable form of apparatus embodying an application of my invention. Fig. 2 is a vertical cross-section showing the interior arrangement of the apparatus shown in Fig. 1. Fig.

' per and 3 is a plan view looking down upon Fig. 1.

Fig. 4 is a plan view looking down ,upon Fig. 5. Fig. 5 is a cross-section on the line 55 of Fig. 4. Fig. 6, is a crosssection on the line 6-6 of Fig. 2,.and Fig. 7 is a plan view looking down upon Fig. 2 with the upper parts removed.

8 is a suitable,form of tank separated by a perforated diaphragm 9 separating theuplower chambers 10 and 11 respectively. The lower chamber is vertically divided into four sections as indicated in Fig. 4 by the reference characters 12 to 15 inclu sive, this division being provided-for'by the partitions 16-17, the partition 17 being cut away at the bottom as indicated at 18 in Figs. 2 and 5.

Referring now to Figs. 1 and 2 it will be seen that the oil inlet is indicated at 19 from which point it is drawn up to the pumps 2021 subject to control valve 20-21 and these pumps are steam driven to feed the oil through the inlets 22-23 into the several compartments 12 to 15 inclusive where it rises passing through the cut-away portion 18 and over the partitions 1617 until it reaches the predetermined height 24 at which point the ball valve 25 being lifted operates the cut-off valve 26 which stops the further feed of oil maintaining the same at a level slightly above the tops of the par titions 16-17 and slightly below the screen 9.

The steam inlet is indicated at 27 Where the steam, preferably superheated, passes through a regulating valve 46 for controlling the pressure or temperature of the heatmg medium for generating gas from the oil in the lower chamber, the steam passing downwardly through the c'oils 28 and again through the coil 29 returning by the tube 30 to the circular chamber 31 connecting with the steam outlet 32. The-steam inlet 27 be ing in communication with the chamber 33 alsofeeds the coils 34 communicatin there with which said coils also supply t e coils served that there is a pipe 41 which supplies the steam pipes4243 which in turn feed the pumps 4445 for supplying the oil to the apparatus, and 46 indicates a suitable valve in the steam supply circuit for controlling the pressure and temperature of steam entering the coils.

From the foregoing it will be seen that the oilvaporized in the lower chamber 11 by the coils 29-35 escapes from the outlet 39, in

the form of vapor or gas while at the same time liquid fuel maybe drawn off from the outlet 38 through a reducing valve 38 and stop valve 48 to the burner 49, the former controlled by the valve 47 and the latter by the valve 48, thus facilitating a proper adjustment of quality of the mixture which may be atomized from the nozzle 49.

It is well known that fuel oil when subjected to temperatures sufiiciently high to boil oil the vapor or gas, forms numerous bubbles which itis desired to break up by providing the perforated diaphragm ,9 so that the gas bubbles are broken up in passing through plate allowing only the gas to pass into the the small-perforations in-the upper chamber, the'gas inthe upper chain her being more effectually superheated by the steam coils in a separate chamber than it could be if it were in the same chamber with the liquid.

Of course it will be understood that various modifications may be made in the construction and arrangement of parts without departing from. the spirit of the invention s cl med.

I claim 1. In an apparatus of the class described, a vertical cylindrical tank divided by vertical bafliing plates, means for maintaining a predetermined level of fuel oil therein,

a perforated plate transversely across said tank, heating a group of coils, above and another group of heating coils below said plate and directly connected, an inlet for a heating medium at the top of said upper coils, an outlet for said heating medium connected at the bottom of said lower coils, and an oil and vaporoutlet below and above said oil.

2. In an apparatus of the class described, a vertical cylindrical tank divided by vertic'al baffling plates, means for maintaining a predetermined level of fuel oil therein, a perforated plate transversely across said tank, heating a group of coils above and another group of heating coils below said plate and directly connected, an inlet for a heating medium at the top of said upper coils, an outlet for said heating medium connected at the bottom of said lower coils, an oil and vapor outlet below and above said oils, respectively and a reducing valve between said tank and said oil outlet.

3. In an apparatus of the class described, a cylindrical chamber having a perforated member dividing the upper and lower portions thereof, separated groups of heating tubes in each of said portions of said tank, compartments in the lower of said tank portions and communication therebetween, and means for taking off liquid and vaporous portions of said oil together.

4. In an apparatus of the class described, a cylindrical chamber having a perforated member dividing the upper and lower portions thereof, separate groups of heating tubes in each of said portions of said tank, compartments in the lower of said tank portions and communication therebetween, means for tali'in'g oif liquid and vaporous portions of said oil together, and means in combination with said tub-es for circulating a heating medium therethrough.

5. In an apparatus of the class described, a cylindrical chamber having a perforated member dividing the upper and lower portions thereof, separate connected groups of heating tubes in each of said portions of said tank, compartments in the lower of said tank portions and communication there between, means for taking off liquid and vaporous portions of said oil together, means in combination with said tubes for 1 ,aeaeoe circulating a heating medium therethrough, an oil outlet and a pressure controlling valve therein, and an atomizer at said oil outlet for atomizing said oil.

6'.

7. In an apparatus of the class described, an oil tank and means for maintaining a Jredetermined level of oil therein, separate heating coils in the upper and groups of separate coils in the lower portions of said tank for vaporizing said oil, means for controlling the outlet of said oil, an atomizer at said outlet for atomizing the same, said atomizer in communication with the vapor generated from said oil in said tank, said upper and lower portions of said tank separated by a partition.
