JOSEPH V. LANDRY, OF KILLONA, LOUISIANA.

OIL-BURNER.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed December 26, 1918. Serial No. 268,262.

This invention relates to burners for va porizing and burning crude oil and the general object of the invention is to provide a burner of this character which is very simple in construction, and which is very eifective.

A further object is to provide a construction of this character in which the oil passing to the discharge nozzle of the burner is sub-divided and passes through a plurality of heating pipes prior to its ejection from the burner so that the oil is vaporized before it is mixed with the steam and ejected.

A further object is to provide very simple means whereby the oil pipes may be cleaned 0r blown out.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a vertical longitudinal sectional view ofmy oil burner; and

Fig. 2 is a section on the line 2-2 of Fi .1.

l ieferring to these drawings, it will be seen that my improved oil burner comprises a steam chamber 10 which is illustrated as cylindrical in form and which is preferably formed of a main section and a head 11 bolted, riveted or otherwise attached to the main section. This main section is formed with a nozzle 12 and into the steam chamber or chest extends the steam pipe 13 connected to a source of steam under pressure.

Extending through the head 11 opposite the nozzle 12 is an oil supply pipe 14 and dis posed in the nozzle 12 is an oil discharge nozzle 15 which is on a line with the pipe 14. Connected tothe inner ends of the pipe 14 and the nozzle 15 are the crosses. Connecting the arms of the crosses 16 are the pipes 17. It will thus be seen that the oil fed to the burner after it enters the steam chamber 10 is divided into a plurality of channels and passes through the relatively small pipes 17 so that all of the oil is thoroughly heated and, as a consequence. vapor ized before it is discharged from the oil nozzle 15.

In order to provide means for cleaning the oil pipes 14, 15, 16 and 17 I provide a steam pipe 18 leading from the steam supply pipe 13 and entering the pipe 14. The main steam supply pipe 18 is provided with a valve 19 between the steam chamber and the junction of the pipe 18 and this pipe 18 is provided'with a valve 20 and also with a valve 21 adjacent the oil pipe 14. This oil pipe is also provided with a valve 22 for controlling the flow of oilto the pipes 17 and the bottom of the chamber 10 has a drainage opening controlled by a cook 23 for removing water from the chamber.

In the operation of this device the valves 20 and 21 are closed and the valve 19 opened and the valve 32 opened. Oil therefore passes into the pipes 17 while steam passes into the interior of the chamber and this steam is under relatively high pressure and its heat vaporizes the oil in the pipes 17. The steam discharges through the nozzle 12 and in doing so sucks out the vaporized oil through the oil nozzle 15 and ejects a stream of steam and vaporized oil from the nozzle 12 into the furnace with which the burner is used. If it be desired to clean the burner the valves 19 and 22 are closed and the valves 20 and 21 are opened. This permits steam to pass through the pipe 18 and into and through the pipes 14, 17 and 15 and blowing out all foreign matter within these pipes.

Inasmuch as the oil is rality of streams while passing through the steam chamber, it will be thoroughly heated so that the final combustion is perfect. Before leaving the burner the oil is thoroughly mixed with the discharging steam jet and leaves the burner in the form of a fine vapor which is ignited near the nozzle and which burns with a white flame. This burning jet in practice has been found to extend far back into the furnace and even up into the flues.

This burner is particularly valuable where crude oil is bein used, but is also capable of being used with any form of oil. The burner may be made of various sizes but the nozzle of the burner is to have a depth equal to the thickness of the furnace wall.

I claim:

1. An oil burner of the character described including a steam chamber adapted divided into a pluto be connected to a source of steam under pressure and having a discharge nozzle, and an oil pipe entering the steam chamber and connecting with a plurality of relatively small pipes extending longitudinally through the steam chamber, and a single nozzle passing into the steam chamber nozzle and with which said plurality of pipes are connected.

2. An oil burner comprising a steam chamber having a steam supply pipe adapted to be connected toa source of steam under pressure, the steam chamber having a nozzle at one end, an oil supply pipe entering the rear end of the steamchamber and connected to a plurality of radiating pipes, longitudinally extending pipes connecting to the radiating pipes and extending longitudinally of the steam chamber, an oil nozzle shorter than and extending into the discharge nozzle ol the chamber and connected to a plurality of radiating pipes at its inner end, to which radiating pipes the longitudinal pipes are connected, and a valve controlling the pres sure of steam Within the chamber.

3. A burner of the character described including a steam chamber formed in two detachable sections and provided With a nozzle, a steam pipe entering the steam chamber, an oil supply pipe entering the rear end of the chamber opposite the nozzle, an oil delivery nozzle extending partially into the steam nozzle, a plurality of pipes connecting the oil nozzle with the oil supply pipe, a branch pipe extending from the steam pipe to the oil supply pipe and having valves adjacent the steam and oil supply pipes, and a drainage cock in the chamber.
