OIL-BURNER.

Specification of Letters Patent.

Patented J an. 21, 1919.

Application iled September 20, 19,18. Serial N o. 254,946.

To all whom t may concern:

Be it known that I, JOHN F. REILLY, a

subject of the King .of Great Britain, and a resident of Central Aguirre, in the county of Guayama, Porto Rico, have invented'a new and Improved Oil-Burner, of whichthe following is a full, clear, and exact description.

This invention relates to Oil burners and particularly to burners which may use crude oil as well as refined oil, and has for an object the provision lof an improved construction wherein the oil is sprayed w1th steam in order t0 secure high efiiciency.

`Anotherobject 'in view is to provlde a bln-'ner having 1a steam and oil inlet wlth a mixing chamber and spraying chamber adjacent its discharge mouth so that the oily will be heated, sprayed and mixed with steam substantially simultaneously.

A still further object of the invention is to provide a burner which is made in a minimum number of ,parts and which acts to produce a proper spray without utilizing any Inovlng parts.

In the accompanying drawing:

Figure 1 is a longitudinal vertical section through a burner disclosing an embodiment of the invention.

Fig. 2 is an end View of the burner shown in Fig. 1. i

Fig. 3 is a 'top plan view of the burner shown in Fig. 1.

Fig. 4 is a rear end view of the structure shown in Fig. 1.

Fig. 5 is a perspective view of the burner with a front section remoyed. f

Flg. 6 is a perspective view of the front section of the burner shown in Fig. 5.

Referring to the accompanying drawing by numerals, l and 2 indicate the feed pipes, pipe 1 supplying steam under pressure, while pipe 2 supplies the fuel oil, which may be crude oil or refined oil as desired. These pipes feed into what may be termed chambers 3 and 4 of the casing 5, which casing has substantially semi-circular openings 6 and 7 opening into the notch 8, which notch,

is filled by a removable front section 9 when the burner is in use as shown in Fig. -1. This section fits snugly and is held in place by suitable screws 10 and 11. Section 9 covers the opening 7 except for the part which registers with the passageway 12, said passage` way leading down to a mixing chamber 13. The opening 6 is partially closed by the section 9 with the exception of a small compara-V tively iiat passageway 14 which is restricted at 15 so as to provide velocity for the steam as it enters the mixing chamber 13. The oil is fed through the assageway l2 at comparatively slow speed) while the steam moves at high speed so that the velocity of the mixture will be considerable and the steam and fuel will quickly and intimately mix into a fine spray, which spray is ignited usually some'distance from the burner. By reason of the mixing chamber 13 and the way the passageways 12 and 14 are provided the discharge mouth or opening 15 directs a combustible mixture to a comparatively great distance or short distance according to the force of the steam. In order to secure the maximum result the mouth 15 is provided with diver ing walls 16 and 17 .whereby the discharge 1s substantially confined between the dotted lines shown in Fig. 3, said discharge being in aflat horizontal fuel oil and the steam are supplied in any desired volume and any desired proportion, the proportion being, of course, adjusted to produce the most eicient action when mixed with the air supplied by any desired air supplying structure.

e burner may be used in steam boilers or in heating devicesnf'anykind where there is a space for the proper use of the sprayed fuel provided by the burner. In connection with the restricted portion 15 it ,will be' observed that the same is restricted vertically,

sheet. ,The

portion is gradually widened from the inner to the outer end of the passageway 14 so as to provide a thin spray or sheet of steam at' comparatively high speed in order to break up the fuel 011 entering the chamber 13 through passageway 12.

What I claim is:

1. -A burner comprising a casing having a pair of spaced chambers, and a notch in the front end merging into the lower part of the .upper chamber and the upper part of the y lower chamber, the bottom of the notch being flat, a removable section fitting into said notch, said removable section having a discharge opening merging into the mixing chamber, saidA discharge opening and mixing chamber having diverging walls, the upper face of the discharge opening being parallel .with the lower face of said notch, whereby the discharge through the discharge opening will be in a thin horizontal sheet, a

passageway extending from one of said Chambers into said mixing chamber in line with the lower part thereof, and a second passageway extending at an appreciable angle to the mixing chamber and merging into the mixing chamber and into one of said first mentioned chambers.

2. A burner comprising a casing having an upper and lower chamber, said upper chamber being adapted to receive a liquid fuel and the lower chamber adapted to receive steam under pressure, a iat horizontal- Leeaen passageway extending from said lower chamber, said passageway being restricted vertically toward the outer end thereof, a diagonal fuel passageway extending .from said fuel chamber to a point intersecting the rst mentioned passageway, and a mixing chamber at the juncture of said passageways merging into a discharge opening, said discharge opening being in the form of a horizontal slot whereby there will be produced a sheet of mixed li uid fuel and steam. l
