' I, that I, JULIUS H. Brenna, a e ,UnitedStates, residingdn the u-nt-yfo f San Francisco and State b a, haveinvented certain new. and ul {Improvements in Liquid-Hydrocarliurnaces,of"which thefollowing is. a

I illy invention has for its object the provision of] a burner or furnace in which 1 5. crude-petroleum, particularly when delivered' with water, can be effectually and economically used asfuel; and to this end my invention consists' iin the novel construction of the combustion chamber and, the means for' supplying the fuel thereto, as I shall hereinafter fully describe, by reference to the accompanying drawings'in which Figure l is a broken perspective view of my liquid hydrocarbon furnace. Fig. 2 is a horizontal crossr section of the same, taken through the flame exit of the shells Fig. 8

is' a similar sectionltaken lower down through ,the door-opening and just above the atomizing orfiring plate.

The shell 1 is composed of suitable refractory material, such as fire brick with an outer' covering of metal. In the shall is formed the combus'tionchamber 2, which has on one side a-door 2", protected by a refractory shield 3', and on the opposite side it is provided with the flame exit 4, which leads toany suitable destination, as, for example,

to a flue under a boiler.

which is also open, terminates suflicient.

distance directly above and in line with the plate 5, to afiord room for readily removing said plate. This removal of the plate is necessary for the substitution of another, as the first burns out, and provision is thus made by the construction shown for the inner boundary the'flue 8, which in its best form is made of fire-brick.

10 is a water supply pipe controlled'by a valve 11.

12 is an oil supply pipe controlled by a valve 13. These pipes 10 and 12. .meet in a delivery pipe '14, the discharge tip 15of which lies just within the open top of the tlue'S.

In operation, an initial fire is made from any suitable fuel in the passage 7, and is continued until the plate 5 is sufficiently heated to vaporize the water which with the oil is dropped upon it.- Thereupon the door 6 is closed and water and'crude petroleum, joining in the pipe 14, are delivered upon the plate 5, as is indicated by the stream 16 in Fig. l. The fall is sufficient to cause the mixed oil and water to spatter and atomizeupon the plate, and the mixture spreading out over the plate, vaporizes and takes fire, and burns with a flame which spreads to all sides of the combustion chamber, and passes around the flue 8 and thence to the exit a. The draftv necessary for combustion comes down the flue 8 with the fall- Jug-fuel mixture.

Gravity alone is here involved in the feed and in the atomizing, and the construction through the tip 1-5 into the flue 8 and drop] of 'the combustion chamber is such that be- 1 cause of the walls of the shell and the walls of the interior flue 8, the maximum area is available.

Having thus described my-inventlon Whatof heat accumulating and retaining surface I claim as new and desire to secure by Let ters Patent is 1. A liquid-hydrocarbon furnace comprisin a shell inclosing a combustion chamber, said shell having in one of its sides a door-controlled opening and in its opposite side a flame exit; a removable firing plate in the lower portion of the chamber, of dimensions adapting it to be inserted and removed through the door-opening; a fine depending from the top of the shell into the combustion chamber and spaced from the walls thereof, said flue opening out above through the topof the shell and opening out below over and spaced from. the firing plate spa cud.

arches springing from the shell walls and supporting the lower end of the flue; and

-means for delivering the liquid fuel into said flue so that it will fall and spatter u on said plate. 7

2. A liquid-hydrocarbon furnace comprising a shell inclosing a combustion chamber, said shell having in one of its sides a doorcontrolled opening and in its opposite side a flame exit, and having formed in its bot-.

tom a passage leading from the exterior and opening up through the floor of the combustion chamber; a removable firing plate in the lower portion of the chamber directly over the inner end of said passage .and of dimensions adapting it to be inserted and removed through the door opening; a flue depending from the top of the shell into the combustion chamber and spaced from the Walls thereof, said flue opening out above through the top --of the shell and opening out below over and spaced from the firing plate; spaced arches springing from theshell Walls and supporting the lower end of the flue; and means for delivering the liquid fuel into said flue so that it will fall and spatterupon said plate.

3. A liquid-hydrocarbon furnace comprising a shell inclosing a combustion chamber and having in one of its sides a flame exit; a firing plate in the lower portion of the combustion chamber; a flue depending from the top of the shell into the combustion chamber and spaced from the walls thereof, said flue opening out above through the top of the shell and opening out below over and spaced from the firing plate; spaced arches springing from the shell walls and supporting the lower end of the flue; and means for delivering the liquid fuel into said flue so that it will fall and spatter upon said plate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
