2 Claims.

gravity feed type in which all mechanically operated instrumentalities are eliminated and in :particular an oil burner in which the oil is fed into a down draught air duct and additional air or Water is fedinto the mixture of air and oil as the mixture reaches the ignition point in the combustion chamber.

In the usual type'of mechanically operated oil burner the oil is atomized or in some cases volatilized by injection under pressure through a stationary or rotating nozzle or through a venturi, but this requires motors and pressure elements which are-costly and require maintenance and this is objectionable particularly in rural communities. With these ends in view this invention contemplates an oil burner wherein the oil passes into a comparatively largedown draught air duct, is ignited in thepres ence of water vapors wherein the oxygen and nitrogen of the air and oxygen and hydrogen ofthe water are liberated providing larger quantities of oxygen for combustion and the air, oil and water vapors are ignited under a shield and blown against the hot surface of a bafile wall inv a furnace or the like.

The purpose of the invention is to provide a simple, efficient and noiseless oil burner wherein all mechanically operated parts are eliminated.

In the oil burner of this invention the gases of combustion ignite first with a blue flame under a shield. then burn with a yellowish flame at the end of the shield, and then as they impinge the hot surface of the bridge wall or baflle a white flame is produced wherein the maximum amount of heat units are produced from the oil or fuel.

The object of this invention is to provide a gravity feed oil burner in the form of a tubular air duct adapted to be installed in the usual residence furnace or heater into which oil may be fed outside of the furnace wall, and which is provided with means for supplying water vapors to the fuel in combustion.

Another object is to provide a gravity feed oil burner having an air duct in which air is drawn downward into the duct.

Another object is to provide means for feeding water in combination with a gravity feed oil burner wherein the water is first converted into steam and then volatilized as it is introduced into a mixture of air and oil.

Another object is to provide a gravity feed oil burner in which the products of combustion are ignited under a protecting shield.

A further object of the invention is to provide an oil burner for residence or industrial use in which all moving parts are eliminated and which is of a simple and economical construction.

' -With these and other objects in View the invention embodies an air duct mounted in the wall of a furnace by a flange'in which the outer end of the ductis flared outward and extends upward and a recess is provided in the lower part of the inner end with the upper part thereof extended and slightly flared outward, and in which oil and water connections are associated with the duct.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure 1 is a view showing a side elevation of a furnace with part broken away showing the burner installed therein.

Figure 2 is a view showing a cross section through the burner on line 2-2 of Figure 4.

Figure 3 is a sectional plan through the lower part of the furnace showing the burner therein.

Figure 4 is a longitudinal section through the burner with the furnace wall and connecting pipes broken away.

Referring now to the drawings wherein like reference characters indicate corresponding parts the oil burner of this invention comprises a tubular air duct [0 having a water jacket II, and an oil supply tube l2, wherein the duct I 0 is mounted in afront wall l3 of a furnace [4 through a flange l5.

The outer end of the air duct I0 is provided with an opening to the atmosphere through an outwardly flared neck l6 and the duct may be provided with a valve [1. The inner end of the duct Hi is formed with an extending or overhanging shield I8 which is flared slightly outward as shown in Figure 3. The duct extends inward through the front wall l3 of a furnace and a wall !9 may be positioned in front of the open end of the duct wherein the burning gases heat the surface of the wall, and then the heat from the wall assists combustion by convection. Additional air may be supplied to the combustion area through an opening 20 in the floor 2| of the furnace.

The oil burner of this invention may be made of any suitable size and is adapted for use in various types of furnaces. The burner is installed in the lower part of the front wall of a furnace with the ducts thereof sloping slightly downward as shown in Figure 1 and oil is supplied through the tube l 2 which is provided with a control valve 22. As heat is generated in the furnace air will be drawn downward through the outwardl flared nipple l6 and the oxygen thereof will be liberated wherein combustion takes place with the greatest eiiiciency', and with the highest possible heatl The oil burner is illustrated and describeda'inr the preferred form, however, it willbeunderstood.

that changes may be made in the design and arrangement of the parts wiflwut'cdepamtm fmm the spirit of the invention.

The burner is illustrated as applied to awe sidence or domestic heating plant, however, it may be made-of 'any'size and maybe used'in industrial or power plants-;- as may be desiredyand for some uses-the upper surfaee'ofthe' burner in the furnace *may-ioe insulated by aE-sheet'or coating 25 of asbestosor the' like'svhlchmaybeheld by ribs 26- and 21 the sides onthe "burner-as shown in Figure 2.
