Assistant Examiner-Larry l. Schwartz Attorne Agent, or Firm-Merriam, Marshall, Shapiro & Klose [5 7] ABSTRACT The invention relates to an atomizing burner, particularly intended for incinerating liquid garbage, and consisting of a supply pipe for the garbage, having circumferentially disposed exits, and being enclosed by an inner jacket through which pressurized atomization medium is supplied, and an outer jacket for supply of air for the combustion, in which burner a number of slots are provided, corresponding to the number of exits for the garbage, and being so designed and positioned adjacent the said exits as to force the pressurized medium from each slot over the adjacent exit for the garbage.
4 Claims, 1 Drawing Figure ATOMIZING an The invention relates to an atomizing burner, particularly for use in combusting liquid combustible waste, said burner consisting of an inlet pipe having radially disposed outlets and being surrounded by an inner jacket, through which a gaseous medium is supplied under pressure in order to atomize the waste, and an outer jacket for the supply of air for the combustion.
This kind of burner is well suited for combustion of liquid waste with a content or more or less solid particles and sludge, in as much as the outlets may have fairly big dimensions.
in known atomizing burners, the jacket through which the atomizing medium is supplied, terminates in an annular slot adjacent the outlets for the combustible material. In order to get a satisfying function, a pressure of 78 atmospheres of the atomizing medium is needed as well as a relatively large surplus of the medium as compared with that required for atomizing in the known burner designs.
The object of the invention is to provide a burner of the said kind for liquid waste, in which the required atomizing can be obtained at a substantially reduced pressure in, and consumption of the atomizing medium, which preferably is air, but may also, for instance, be steam.
According to the invention this is attained by the inner jacket having a number of outlet slots for the atomizing medium, corresponding to the number of outlets for the liquid combustible waste, the said slots being of a length corresponding to the diameter or width of the outlets for the waste, and being thus placed adjacent the latter outlets that the atomizing medium for each of the said slots passes over one of the outlets for the waste.
This design results in all of the supplied atomizing medium being concentrated at the places where it is most effective, namely where the conbustible waste leaves the outlets in the supply pipe, while atomizing medium is not directly supplied to the spaces between the said outlets. This means that the supplied amount of the medium is substantially reduced, and that at the same time the pressure may be correspondingly reduced while maintaining the same velocity of outflow and thus the same degree of atomizing.
The slots for supplying the atomizing medium can thus be placed flush with the outlets for the waste in the axial direction of the supply pipe, but according to an embodiment of the subject of the invention, they can also be in a displaced position relative to the waste outlets, but being so designed that the atomizing medium is guided over the latter. This results in the atomized waste being forced into a rotating movement favouring its mixture with the air of combustion.
The latter is supplied through the outer shell of the atomizing burner, whereby the latter in a manner known per se may be provided with guide blades imparting a rotary movement to the air of combustion to ensure a good admixture with the atomized waste.
An embodiment of an atomizing burner according to the invention is illustrated in the accompanying drawing showing the burner in part section.
The burner ll consists of an inlet pipe 2 for liquid combustible waste. The pipe 2 is closed at the front, and adjacent to the latter it has a series of circular openings 3, through which the waste can leave the pipe.
The supply pipe is surrounded by an inner jacket 4, to which an atomizing medium can be supplied through a conduct 5.
Corresponding to each of the openings 3, and flush with the latter, narrow slots 6 are present where the jacket 4 is connected with the inlet pipe 2, the length of said slots being equal to the diameter of the openings 3, and the slots being placed so as to be flush with said openings in the axial direction of the inlet pipe.
The jacket 4 is enclosed by an outer jacket 7, being open at the front end, and serving for supplying air of combustion, said outer jacket having oblique guide blades 8 serving to impart a rotary movement to the air of combustion.
I claim:
1. An atomizing burner for combusting liquid waste, which comprises:
a. a pipe to which the waste is supplied, having a closed front end and circumferentially disposed outlets for the waste adjacent the front end,
b. surrounding said pipe an inner jacket having a number of outlet slots being placed adjacent to and corresponding to the number of outlets for the waste,
c. means for supplying a gaseous. medium under pressure to the inner jacket,
(1. an outer jacket surrounding the inner jacket and being open at the front end, and
e. means for supplying air of combustion to the outer jacket.
2. An atomizing burner according to claim 1, in which the outlet slots for the pressurized gaseous medium are axially on line with the outlets for the liquid waste.
3. An atomizing burner according to claim 1, in which the outlet slots for the pressurized gaseous medium are axially displaced in relation to the outlets for the liquid waste, and so designed as to guide the pressurized gaseous medium over the waste outlets.
4-. An atomizing burner according to claim 1, in which oblique guide blades are provided in the space between the outer and inner jackets.

An atomizing burner for combusting liquid waste, which comprises: a. a pipe to which the waste is supplied, having a closed front end and circumferentially disposed outlets for the waste adjacent the front end, b. surrounding said pipe an inner jacket having a number of outlet slots being placed adjacent to and corresponding to the number of outlets for the waste, c. means for supplying a gaseous medium under pressure to the inner jacket, d. an outer jacket surrounding the inner jacket and being open at the front end, and e. means for supplying air of combustion to the outer jacket.
2. An atomizing burner according to claim 1, in which the outlet slots for the pressurized gaseous medium are axially on line with the outlets for the liquid waste.
3. An atomizing burner according to claim 1, in which the outlet slots for the pressurized gaseous medium are axially displaced in relation to the outlets for the liquid waste, and so designed as to guide the pressurized gaseous medium over the waste outlets.
4. An atomizing burner according to claim 1, in which oblique guide blades are provided in the space between the outer and inner jackets.
