- In Argentina December 12, 1938 I The present invention relates to a of burner for liquid fuels.

In the' burning of fuels of a liquid natureV diiculties are experienced in avoiding lthe presence of carboniferous residues and the formation of monoxides which will interfere with the It is thereforean simple manner all such difficulties by admitting the fuel at the middle partkof the burner, in a continuous manner or, inthe 'case of liquid fuels,V

to cause the'liquid to ow down directly along the walls, of the burner.

novel type 1 claim. (ci. 15s- 4) walls of the burner, this view clearly showing all the lpartsof the unit. Fig. 2 represents the disc providedwith deflec'- Y tor blades which serves as a covering member for I the upper frusto-conical member.

'Ihe upperpo'rtion of the unit is formed of an inverted frusto-conical member l having-a cover in the shape of `a disc 2 formed with cuts t whereby it'acquires the shape of deector blades.

The frusto-conical member I is connected at its Vsmaller end to a frusta-conical member 9 Y Y thereby forming a seating 3^ formed with a groove In order to improve conditions of draft inthe system use is made of a baille or partitionV at the Y rear portionA between the burner element and the support of the unit so that the natural draft created within'tlle burner cooperates in the gasication of the liquid fuel. Y

The aforementioned problems are solved in a simple and efficient manner by providing an in- 4 which directly receives the liquid fuel from a tank 6 by means of a duct 5. Upon'the seat 3 is seatedan annular'member Y 'l also conical at its inner portion and which, in

combination with the lower level of seat 3', 'forms a groove 8 along which the fuel flows.,

The frusto-conical member 9 `is a continuation of the member l and is joined thereto with its smaller end, A'and'is supportedk onv a block of material' Il, preferably of refractory material, at its cavity VIl), whereby a certain clearance is provided between the edge I3 and the cavity.

Thus the liquidgcontained in the tank` 6 ows down fromthe groove 8 ontheinternal surface i of the 'lrlelrlbery 9, which Lduring operation is in In orderk to permit of the escape of the combustion gases, and to Vcreate a natural draft, the base is made of concave shape, so that the gaseous products of combustion escape along the curved surfaces thereof.

A feature of the presentV invention is the provision of 'means for the gradual admission of fuel in accordance with the requirements; A further feature 0f the invention pertains to the provision of means that will facilitate the discharge or escape of the combustion gases, and, simula heated condition-.and the liquid is completely gasifled. v Y l v 'I'he air of combustion is admitted through the disc 2 whereby it is forced to effect a whirlingV motion, this facilitating a perfect mixture of the;` fuel with the oxygenv from the air. l j

lIt is obvious that any kind of rmodifications orl amendments may be made without exceeding the scope of the present invention, as clearly Y defined in the appended claim.V

A stillfurther feature of the invention is the provision of air defiecting means by which the air receives a Ywhirling motion,l whereby the airV is brought into intimate contact withlthe fuel' it being possible thus to secure maximum output.

Other features and advantages will appear from an inspection of the drawing wherein are shownby rwayof example an embodiment of Vthe invention, and to which reference willA be had below, the following being a detailed description of the invention* V; Y
