Definitions

  • a burner plate which comprises depressions on the radiating side and combustion passages arranged parallel to each other for conveying the fuel-air mixture from the mixture side to the radiating side of the plate, in which at least one of the combustion passages is coaxially arranged at the bottom of the respective pertaining depression whereas the other combustion passages are distributed over the sides of the depressions and the plate surface between the sides of the depressions, the combustion passages being distributed over the de' pressions and the radiating surface in such a way that the flames being generated will so uniformly act upon the lateral surface of the depressions and the radiating surface of the plate therebetween that the temperature being generated in the depressions .will substantially equal the temperature generated at the radiating surface between the lateral surfaces of the depressions.
  • the present invention relates to a burner plate for infrared radiators having depressions on the radiating side and having combustion passages for conveying the fuel-air mixture from the mixing side of the plate to the radiating side, the combustion passages being arranged parallel to each other while at least one of the combustion passages is coaxially arranged at the bottom of a depression whereas the other combustion passages are distributed over the sides of the depressionsand over the surfaces between the depressions.
  • the depressions have an inwardly directed inclination and are deeper than their width, the lateral surfaces being designed with an appropriate curvature and having bevel surfaces inclided toward each other.
  • the combustion passages are arranged in three different planes and, more specifically, one of the combustion passages each is located at the bottom of the depressions while thereabove in the bevel surfaces, i.e., the lateral surfaces within the depressions, there is circularly arranged a plurality of combustion passages. Additional combustion passages are distributed over the surfaces between the depressions.
  • FIG. 1 illustrates a top view of a burner plate according to the invention.
  • FIG. 2 represents a section taken along the line II II of FIG. 1.
  • FIG. 3, 3a and 3b respectively illustrate three different cross sections of depressions in burner plates according to the invention.
  • FIG. 4 is a diagrammatic illustration of the distribution of the radiation in a semi-body.
  • FIG. 5 shows a vertical section through a burner plate according to the invention but on a larger scale than that of FIGS. 1 and 2.
  • the burner plate according to the invention is characterized primarily in that the combustion passages are distributed over the depressions and the webs of material therebetween in such a way that theflames which form will act so uniformly upon the lateral surfaces of the depressions on the one hand and on the webs therebetween on the other hand that the temperature obtained in the depressions will approximately equal the temperature obtained at the surface of the webs.
  • the depressions are formed by cylinders which may taper to that side which faces away from the radiating side while at the bottom of each cylinder there is provided at least one cylindrical combustion passage.
  • the device is furthermore characterized in that centrally about the center of the bottom of each depression further cylindrical'combustion passages are so arranged that their center points are intersected by the circular circumferential line of the cylindrical part of the depressions and that the mouths of each combustion passage is divided into two parts located in different planes.
  • the inner part is located in the bottom or the conical portion and-is confined by that circular intersecting edge of the cylindrical part of the depression which faces away from the radiating side or by the bottom of the depression, whereas the other part is located thereabove on the radiating surface of the burner plate.
  • the depression consists of acylinder which to that side which faces away fromthe radiating side merges with a hollow cone standing on its tip.
  • the semicircular mouths of the combustion passages I at the upper edge of the depressions and located one adjacent the other together form an extension of the cylindrical depression in the shape of a collar or flange.
  • the passages located in the webs will be surrounded on all sides by strongly heated walls whereby a further heating up will occur in addition to the heating up due to the combustion taking place therein.
  • the highly heated inner walls of the depressions radiate the absorbed heat back to the oppositely located walls whereby an additional heating up will take place.
  • all of the generated heat is taken advantage of for heating up the ceramic surfaces so that an intensely heated up glowing radiating surface is obtained which consists not only of the webs located between the depressions but also comprises the bottoms of the depressions, all of the surfaces of the inner walls formed by the semi-cylinders, and also the webs of material located between the depressions.
  • the radiation is directed inwardly into the hollow chamber of the depressions and not into the ceramic material.
  • turbulence is supposed to result which would furnish a more favorable combustion due to an increased intake of air.
  • the radiating surface consists merely of the webs of material located between the depressions.
  • six passages are uniformly distributed around the combustion passage provided in the tip of the cone, whereas between the individual depressions precisely in the center point between each three triangularly arranged depressions there is provided a further'passage of the same diameter.
  • FIG. 1 shows three rows of depressions 2 at the radiating side of the burner plate 1, the depressions of one row being offset with regard to the depressions of the adjacent row.
  • a combustion passage 3 Centrally arranged at the bottom ofeach depression is a combustion passage 3 which according to one specific embodiment of the invention has a diameter of 1.3
  • the combustion passages 4 which have the same diameter as the combustion passages 3 are arranged 4 are located in a plane which passes through the axis of the passage 3.
  • the combustion passage 7 leads to the surface of the burner plate, in other words to the surface of the web portion 8 of the plate.
  • the depressions 2 have the specific shape shown in FIG. 3 according to which the conical portion has an inclination of approximately while the depression itself has a depth of approximately 3 mm.
  • the combustion passages 4 have a diameter of approximately 1.3 mm.
  • FIGS. 3a and 3b diagrammatically illustrate other possible, configurations of depressions 2a and 2b.
  • FIG. 4 illustrates the experimentally ascertained distribution of the heat rays 10 emanating from the ceramic plate according to'the invention and directed onto an imaginary surface of half a chamber.
  • FIG. 5 illustrates on an enlarged scale a vertical section through a depression 2. According to this showing, the course of the front of the flame .is indicated by heavy lines 9.
  • F IG. 5 due to the combustion occurring in the passages shortly ahead of the mouths thereof, thereis formed a heating zone which envelops the depression 2 and the web 8 and re-' passages passing therethrough from the mixture side to the radiating side to convey a fuel-air mixture for combustion on the radiating side of said plate, said radiating side of said plate being substantially flat with cylindrical depressions formed therein, each surrounded by said flat surface and having a peripheral side extending below said surface with the bottom of the depression converging to a central point of greatest depth, each depression having a passage ending in its central point of greatestdepth and a plurality of other passages surrounding said central passage and intersecting its side to form semi-cylinders in the depressions, and further a plurality of said passages extending through said flat surface between said depressions, said combustion passages being distributed over said depressions and said flat
  • a burner plate according to claim 1 in which adjacent depressions are separated by a flat surface of less width than the diameter of a depression, the bottoms and sides with semi-cylinders formed by said depressions with intersecting passages forming layer radiating surfaces at different levels than the radiating surface of the flat surface.
  • a burner plate in combination according to claim sions the arrangement being such that each of said groups having the axes of its combustion passages located along an imaginary cylinder wall coaxial with the pertaining depression while the mouth of each of said other combustion passages is located in different planes, one of said planes being within the region of the bottom of the respective recess, and the other plane substantially coinciding with said radiating side.
