Definitions

  • the present invention relates to a wafer with a honeycombed radiant face for a radiant burner.
  • the cells formed leave a number of holes between them which do not thus participate in the increase in the radiating power of the wafer.
  • the object of the invention is to remedy the aforementioned drawbacks, and others, of known embodiments, by means of a plate with a dimpled front face for a radiant burner, formed of a ceramic material, comprising rows of holes. passage of oxidant-fuel mixture, and in which it is possible to provide cells regularly distributed in rows and involving all the holes existing in the wafer.
  • the invention relates to a plate for a radiant burner, as defined in claim 1.
  • Figure 1 there is shown, in plan view, part of a plate for radiant burner having several rows of holes designated by T and we have highlighted the geometric processes which allow to obtain the patterns of regular distribution cells in the radiating face of the wafer according to the present invention.
  • the cells to be provided in the wafer are defined by their theoretical base, that is to say their geometric base, and their depth profile.
  • the actual shape of the cells is then determined from the theoretical profile, taking into account the conditions of implementation, such as the technological conditions of machining, molding and other shaping.
  • the distribution pattern corresponding to point 0 1 is not unique. Indeed, from point A 1 , we can draw a parallel vector, of the same length and in the same direction as the vector on the left, which gives the vector
  • FIG. 2 the patterns of distribution of cells which can be obtained are shown, for a distribution of holes corresponding to an equilateral quinconcing in which cells are obtained in the form of a regular hexagon.
  • AV1 to AV 7 we designated by AV1 to AV 7 , and by solid lines, the cells of the type obtained from the right vector and by AV ' i to AV' 4 , and by dashed lines, the cells of the patterns obtained. from the vector on the left.
  • the form milling process was adopted and, to allow the cutter to pass, the solution consisting of angularly shifting the basic hexagons of the cells was adopted.
  • FIGS. 7A to 7E some examples of depth profiles have been indicated which it is possible to adopt for the cells, in particular a hemispherical profile, a truncated conical profile, a stepped cylindrical profile and a simple cylindrical profile. It is possible to envisage other profiles, for example profiles of surfaces of revolution such as paraboloids or composite profiles such as cylindro-conical.
  • the angle at the top of the bottom of the cell, starting from the center of the central hole of said cell is between approximately 30 and 180 °.
  • the depth of the cells should preferably be between 0.5 mm and 3/5 of the thickness of the insert.
  • the orifices provided in the wafer are preferably cylindrical and have a diameter of between approximately 0.4 and 5 mm.
  • the equivalent diameter of the theoretical cell base is defined by the sum of the diameters of two neighboring holes and the thickness of material between these two holes.

Platte für Strahlungsbrenner aus einem keramischen Werkstoff mit die Platte durchsetzenden Leitungen korrespondierenden Durchlassöffnungen für das Sauerstoffträger-Brennstoffgemisch, die in der Platte gleichmässig ausgebildet und in absolut homogener Form in parallelen Reihen versetzt angeordnet sind, wobei der Abstand zwischen je zwei Durchlassöffnungen immer der gleiche ist und ein System von regelmassigen, sechseckigen zellen (AV, AV1) entsteht, die in die Brennfläche dieser Platte eingelassen sind, und jede Zelle eine Mitteldurchlassöffnung (T1) und sechs Randdurchlassöffnungen aufweist, von denen jede durch Radiusvektoren
Figure imgb0005
geometrisch mit der Mitteldurchlassöffnung verbunden ist, dadurch gekennzeichnet, dass jede Durchlassöffnung zumindest teilweise innerhalb einer Zelle liegt, und dass die Zellen so verteilt sind, dass jede von ihnen durch Verschieben um einen vektor (l ) aus einer anderen abgeleitet ist, der der geometrischen Summe eines Vektors entspricht, der gleich dem geometrischen Doppel eines Radiusvektors (DA) und des unmittelbar links oder rechts benachbarten Radiusvektors () der anderen Zelle ist, wobei die Zellen um einen bestimmten Winkel um die Mitteldurchlassöffnung mit Bezug auf das Sechseck gedreht sind, das aus der Verbindung der äussersten Punkte dieser Radiusvektoren untereinander entsteht, durch die die Mitteldurchlassöffnung mit den Randdurchlassöffnungen verbunden wird, und jede Randdurchlassöffnung sich beidseitig einer Aussenkante des durch die Zelle gebildeten Sechsecks erstreckt.
2. Platte gemäss Anspruch 1, dadurch gekennzeichnet, dass mindestens eine Durchlassöffnung jeder Zelle verschlossen ist.
3. Platte gemäss Anspruch 1, dadurch gekennzeichnet, dass jede Zelle mindestens auf einem Teil ihres Grundes das Profil einer Rotationsfläche aufweist.
