Description

G. RUGGIERO Dec. 4, 1934.
BURNER Filed Sept. 28, 1953 INVENTOR.
ATTORNEY.
Patented Dec. 4, 1934 UNITED STATES PATENT OFFICE 2 Claims.
This invention relates to a gaseous fuel burner and has for its principal object to secure more nearly complete combustion of the fuel and a higher temperature relative to the amount of fuel consumed. A further object is to return from i further object is to prevent or greatly reduce the amount of incompletely burned or unburned fuel escaping into the atmosphere of the room in which the device operates.
With these and other more limited objects in view, as will become apparent, the invention consists in the construction and arrangement of parts hereinafter described and pointed out in the appended claims. While the device is susceptible of use in other relations, such as domestic furnaces and the like, it is described in particular relation to cooking ranges and is so illustrated in the accompanying drawing in which Fig. 1 is a plan view of a burner embodying my invention; Fig. 2 is a central longitudinal section therethrough and Fig. 3 is a fragmentary section corresponding substantially to the line 3-3 of Fig. 2.
Referring now to the drawing, numeral 10 indicates a burner of usual construction to the interior 11 of which is suplied a combustible mixture through a tubular portion 12, the interior 13 of which may be termed a mixing chamber. Extending into the mixing chamber 13 is a fuel supply tube 14 which may be connected to a source of natural gas or the like and which will produce an injector action tending to cause a flow of gaseous material from the passage 15 around the curved portion 16 into the mixing chamber 13.
The passage 15;, communicates with the interior of a manifold portion 17 which is provided region of the burner and terminating a short distance thereabove, as is clearly indicated in the drawing.
The burner portion 10 willcarry a plurality of flames extending upwardly therefrom and the tubes 18 will be positioned at such height above the upper surface of the burner that the suction downwardly therethrough will cause an optimum mixture of unburned and partially burned fuel, productsof combustion and air to be supplied to the mixing chamber 13. It is to be understood that the number and location of these tubes, as shown, is illustrative merely and that a larger or smaller number may be provided and may be located in any desired positions relative to the burner parts. For example, these tubes may be placed in the angle between the arms of the burner as shown and, if desired, one may extend upwardly through the central opening 19. The height of the tubes 18 may be adjusted for optiwith upstanding tubes 18 passing upwardly in the mum results according to their relative position with respect to the burner, the kind of fuel employed and the character of the flame carried by the burner.
It will be observed that the ring shaped passage 20 is closely adjacent the bottom of the burner while the elongated passage 15 is closely adjacent the mixing chamber 13, being separated therefrom respectively by a comparatively thin metal wall. The fuel passing through the mixing chamber and burner will thus be heated by conduction as Well as by admixture with the heated gases from the region of the flame.
In operation, a mixture of unburned fuel, products of combustion and fresh air are carried downwardly through the tubes 18 and mixed with fuelsupplied through the injector tube 14, in the mixing chamber 13, and burned above the openings in the burner. By supplying the heated gaseous mixture instead of ordinary cold primary air, I am able to secure a hotter flame, use a leaner mixture and obtain a higher efficiency than is possible with burners of ordinary construction.
While I have shown and described the preferred embodiment of my invention I wish it understood that I am not limited to the details thereof but only in accordance with the spirit and scope of the appended claims.
Having thus described my invention, what I claim is:
1. In a device of the character described, a burner, a mixing chamber communicating therewith, an injector tube adapted to supply fuel to said mixing chamber, and means for supplying to said mixing chamber a mixture of air and other gases from the vicinity of the flame, said means including a plurality of tubes terminating adjacent the flame carried by said burner and communicating with a ring passage below said burner and said ring passage communicating with said mixing chamber through an elongated passage, said passages being closely adjacent to said burner and mixing chamber whereby to heat fuel in the latter.
2. In a device of the character described, a burner, a mixing chamber communicating therewith, an injector tube adapted to supply fuel to said mixing chamber, and means for supplying to said mixing chamber a mixture of air and other gases from the vicinity of the flame, said last means including a plurality of tubes terminating adjacent the flame and having their interiors in communication with a passage below said burner and said passage communicating with said mixing chamber through an elongated passage, said passages being closely adjacent to said burner and mixing chamber whereby to heat fuel in the latter.
