Nov. 29, 1966 A. VAN DE ROER GAS BURNER Filed May 21, 1964 I I i 12 13 INVENTOR FkAucisKvs A. VAN de Rome BY y-.
ATTORNEYS United States Patent 3,288,377 GAS BURNER F ranciskus A. van de Roer, Statensingel 98A, Rotterdam, Netherlands Filed May 21, 1964, Ser. No. 369,261 Claims priority, application Netherlands, May 24, 1963, 293,171 7 Claims. (Cl. 239-433) The present invention relates to a gas burner comprising an air-gas mixing device and one or more burner tubes provided with burner ports.
The known gas burners of this kind comprise burner tubes in which the burner ports have been provided during the casting of the burner tubes or have been provided by means of a cutting operation. It is an object of the invention to provide a gas burner of this kind having several advantages in view of the known burners. According to the invention said burner ports form a part of separate burner heads mounted on said burner tubes said ports being bounded by parallel flat surfaces extending over a certain height, the ends of said ports of the same burner head or of adjacent burner heads being arranged in close proximity to each other. Owing to the fact that the burner heads form separate units it is possible to use a special material for these burner heads, whereas the remaining part of the burner can be made of an other material which with reference to the resistance against high temperatures needs to meet less high requirements. Further the separate burner heads make it possible that the burner slits have a certain height such that a flashing back of the flame is prevented. Moreover the flames can be supplied with plenty of air.
According to the invention the free edges of said parallel surfaces at least partially have the shape of an arc and the ports of adjacent burner heads in a top view are lying parallel to each other and overlap each other such that in a projection normal to said parallel surfaces said ports intersect each other. In such an embodiment upon the lighting of the burner the flames pass from the one port to the next one even if the burner is in the position for small flames.
In a preferable embodiment according to the invention said slit like shaped burner ports of the same burner head intersect each other and at the point of intersection of the parts of said slits a small pin is arranged such that said pin contacts the ends of the parallel surfaces of said slit parts. In such an embodiment the risk of flashing back of the flames due to the smaller wall surface at the point where the slit parts meet, is eliminated whereas the passing of the flame from the one part of the slit to the other remains possible. Further by means of the small pin the rigidity of the flat walls of the slits is increased,
According to the invention each burner head can have a slit with at both sides one or more slits directed normally to said first slit, said first slit extending into close proximity to the corresponding slits of the adjacent burner heads of the same burner tube, the transverse slits extending into close proximity to the corresponding transverse slits of a burner head of an adjacent burner tube. In such an embodiment it is possible to arrange a, very large burner capacity inside a small space whereas it remains possible to supply the flames with suflicient air.
For the sake of completeness it is remarked that it is known per se to construct a burner out of small separate burner units. In such a case however each burner unit comprises an own air-gas mixing device; The construction of such a unit is far more complicated than that of the burner heads according to the invention. Further such an embodiment of the burner has the disadvantage that under certain conditions the flame can flash back along 3,288,377 Patented Nov. 29, 1966 ice the outer side of the burner unit to the outlet orifice of the injector.
The burner according to the invention can be executed as a burner for standard gas.
The invention will be elucidated in the following description of some embodiments shown in the drawing.
In the drawing:
FIG. 1 is a burner head comprising one single slit;
FIG. 2 is a burner head comprising two slits intersecting each other;
FIG. 3 is a burner head comprising a slit with at both sides two transverse slits;
FIG. 4 is a top view of a gas burner consisting of a plurality of burner tubes provided with burner heads according to FIG. 3; and
FIG. 5 is an end view of the burner taken on line VV of FIG. 4.
The burner head according to FIG, 1 shows one single burner slit 1 which over a certain height is bounded by flat surfaces 2. The burner head can for example have the shape of a flattened funnel. At its lower end the burner head comprises a circular connecting piece 3 for the attachment 0f the burner head in the burner tube.
The burner head according to FIG. 2 shows two slits 4 and 5 which intersect each other and are also bounded by flat surfaces. At the point where the slit parts meet a small pin 6 has been arranged, said pin 6 contacting the edges of the flat walls bounding said slit parts. The burner head according to FIG. 2 also comprises a circular connecting piece 7.
The burner head according to FIG. 3 shows a slit 8 with at both sides transverse slits 9 and 10. Also these slits are bounded by parallel flat surfaces. At its lower end this burner head comprises a connecting piece 11 by means of which it is attached to one of the burner tubes 12 through an orifice 13. These tubes are schematically indicated in FIGS. 4 and 5. Each burner tube 12 has been provided with a gas injector 14 and a mixing section 15 At the point of intersection of the slit parts 8, 9 and 10 small pins 16 have been arranged.
In a top view the slit parts 8 of the burner heads attached to the same burner tube 12 are lying parallel to each other and overlap each other. The transverse slits 9 and 10 of the burner heads which are attached to adjacent burner tubes are also lying parallel to each other and also overlap each other. In such an embodiment it is possible to give the burner a very large burner capacity whereas the burner occupies only a small space. Between the flat walls bounding the burner slits there is ample space for secondary air flowing to the flames. Owing to the curved upper edges of the slit parts, these parts are intersecting each other in a side view at the point of overlapping. This gives the security that also in the case of an incorrect mounting of the burner heads the flames will pass easily from the one burner head to the adjacent burner head.
What I claim is:
1. A gas burner comprising an air-gas mixing device, a burner tube, and a plurality of burner heads mounted on said tube, said heads each including a hollow body terminating in a plurality of burner ports, each of said ports being a slit bounded by parallel fiat surfaces, each burner head having a first slit intersected by at least one transverse slit, said first slit lying substantially parallel and extending into close and overlapping proximity to the corresponding first slit of an adjacent burner head.
2. A gas burner according to claim 1 wherein is provided a plurality of burner tubes each having a plurality of said burner heads, said transverse slit of a burner head on one burner tube also lying parallel and extending into close and overlapping proximity to the corresponding transverse slit of an adjacent burner head on another burner tube.
3. A gas burner according to claim 1, wherein the free edges of said parallel surfaces bounding said slits are at least slightly curved so that in a projection normal to said parallel surfaces said corresponding slits intersect each other.
4. A gas burner according to claim 1, in which a small pin is inserted in the point of intersection of the intersecting slit-like shaped burner ports in the same burner head, said pin contacting the parallel surfaces bounding said slit-like burner ports to define a wall dividing the slits into separate portions.
5. A gas burner according to claim 1 wherein each of said burner heads is provided with two transverse slits intersecting said first slit one on each side of the center of the first slit.
6. A gas burner according to claim 1 wherein said first slit of each burner head lies at a slight angle to the axis of the burner tube as viewed from above the burner ports.
7. A gas burner according to claim 1 wherein the hollow body of each of said burner heads increases in size with distance from the burner tube and toward said ports so as to considerably elongate said parallel fiat surfaces forming said slits.
