Application filed November 4,1924. Serial No. 747,736.
This invention relates to burners, and particularly to that form of burner known as the external atomizing type. The burner is particularly useful where a high heat is desired for use in brick kilns and the like, as the burner is exceedingly eflicient and willreadily melt most substances. The invention has for an object to provide a burner which is low in cost of maintenance, simple of construction, which is so formed as to eliminate repairs and the necessity of frequent cleanings and which is totally devoid of complicated parts. A further object is the provi sion of a burner which will use a low gravity residuum and a burner in which dirt, water or other foreign substances in the burnable fluid will not affect the operation of the burner.
A further object is the provision of a burner which will operate equally well with g a gas or fluid such as oil.
A further object is the provision of a burner which gives a steady flame practically without any pulsations, and in which a large flame or a small flame may be had by simple regulation.
lVith the above and other objects in view, the invention consists in the novel and useful provision, formation, construction, association and relative arrangement of parts, members and features, all as shown in certain embodiments in the accompanying drawing, described generally, and more particularly pointed out in the claims.
In the drawing:
Figure l is a perspective view of the improved. burner;
Figure 2 is an enlarged longitudinal cross sectional view of the burner, and taken on the line 2-2 of Fig. 3; and
Figure 3 is an end elevation showing the nozzle end of the burner, the same being on an enlarged scale from the showing of Fig. 1.
Corresponding parts in all the figures are designated by the same reference characters.
Referring with particularity to the drawing, A designates as an entirety and in one embodiment, the complete burner, and of such burner a is the burner housing and b the burner nozzle. The burner housing is formed with two longitudinal bores extending from end to end and designated as 1 and 2.
The wall surrounding a part of the bore 1 as shown at'3 for recep screw-threaded end of a pipe 4.
steady flame, resides in the fact that air isdrawn rapidly inwardly towards the nozzle which disturbs the even and constant flow of the burnable fluid to the nozzle, but with the arrangement just shown the fluid is kept practically out of contact with the indrawn air and a steady flame results. The nozzle 5 is in a plug form, being provided with screw threads as shown at 8 for screw-threaded engagement with the screw threads 6, and said nozzle is provided with one or more bores 9, there being two of such bores shown in Fig. 3. Likewise the nozzle is provided with two spaced wings 10 and 11, the space between such members 10 and 11 being in direct communication with the openings 9. As will be noted the members 10 and 11 extend outwardly from the front face 12 of the nozzle end of the burner.
In operation the burner nozzle is screwthreaded within the bore 2 so that the openings, of which there are two, as shown -in Fig. 3, are inalignment channel 6. Oil is fed from a suitable source of supply through the line 4 into the bore 1, and then flows downwardly toward the openings 9 being guided in its movement by the channel 0. Steam under pressure is conducted to the bore 2 by the pipe 7 and is forced through the openings 9 and the oil upon contact with the steam is thrown outwardly in the form of a thin vapor, and likewise guided in its outward movement by the spaced wings 10 and 11. this type will throw a flame a of feet, according to the steam pressure. The flame practically does not pulsate, due to the fact, as has been stated, that the oil or other fluid is not influenced by air drawn inwardly toward the nozzle due to the high great number surrounding the bore 2 are serewtransversely of the A burner of velocity of: the steam forced through the openings 9. Air of course is drawn inwardl v at the top and bottom'of the burner at the channel portions. This burner will also give a large or small flame simply by regulating the steam pressure; a factor of great importance for the reason that the average burner on the market today will immediatelv go out when the steam pressure is lowered. If it were desired to use-gas as fuel in place of oil the position of the burner shown in Fig; 1 would be inverted; that is to say, the plug would he at the top and the opening 1 at the bottom. Due to the fact that gases risefcombnstion of the gas would take place the sa -me as it oil were used. This burner gives perfect expansion of any gas used as a fuel.
It is obvious that various-changes and modificationsand variations'may he made in practicing the inventiond in departure from the particular showing, without departing fron rthe true spirit of the invention.
Having thus disclosed my invention, I claim and desire to secure by Letters Patent: l. A'device of the character-disclosed, ineluding a burner housing provided with two spaced bores; said burner housing at one end being pro-videdwvith a channel with which such bores comnlnnicate. and a nozzle provided with two spaced wings extending from one of said bores and beyond the burner housing.
2'. A device of the character disclosed including a burner housing providedwith two spaced bores: said burner housing at one end being:- provided with a channel with STEVE BULLUM.
