Definitions

  • ABSTRACT A radiant burner comprises a mixing chamber for a combustible gaseous mixture delimited by an emission plate through which the mixture passes and on the outer surface of which the mixture is ignited, the plate being surmounted by an anti-convection screen.
  • An auxiliary emission plate is provided between the emission plate and the screen, spaced from both emission plate and screen and provided with passages by which the spaces on either face of the axuiliary emission plate are placed in communication.
  • This invention relates to a radiant burner designed to burn a combustible gaseous mixture, the basic fuel being either a gas or a sprayed liquid. More particularly, but not exclusively the invention concerns a burner which is able to reach high temperatures and especially temperatures exceeding l,200C.
  • Burners in the first group consisting of radiant tubes inside which combustion occurs, do not allow a homogeneous temperature distribution and are difficult to use, their operating flexibility being low. by operating flexibility we mean the possibility of using the burner in optimum conditions in terms of a given range of temperatures. Thus, in the case of this group of burners, the optimum operating condition can only be reached within a narrow temperature range.
  • the second group of burners consists of so-called impact burners in which the flame strikes a refractory element which radiates the heat. These burners have the same faults as those in the first group.
  • Burners in the third group consist of those in which the flame is situated at the outlet of a ceramic plate which may be surmounted by a front metal grill. These burners which have a better flexibility of operation than the burners mentioned above, are not however capable of exceeding temperatures of from 980 to Burners in the fourth group consist of those having a gas outlet element in metal which is fixed underneath a metal grill. This type of burner enables temperatures of over l,0OOC to be reached,.but here again, flexibility of operation is relatively low.
  • a radiant burner for a combustible gaseous mixture comprising mixing chamber for gaseous mixture and delimited by an emission plate adapted to permit passage of the gaseous mixture. therethrough, said mixture being, in use, ignited on the outer surface of said emission plate, said emission plate being surmounted by an anti-convection screen spaced from the said emission plate, wherein an auxiliary emission means is provided between the emission plate and the screen and spaced from both the plate and the screen, said auxiliary emission means comprising a plate of refractory material covering substantially the whole of the burner surface and having a large number of channels therethrough connecting the space between the emission plate and the auxiliary emission plate with the space betweenthe latter and the screen.
  • the auxiliary emission element is advantageously made of a plate of refractory material provided with communicating channels joining the space between the emission plate and the auxiliary emission plate with the space between the latter and the screen and enabling the products of combustion to be expelled.
  • the refractory material may advantageously be a suitable metal.
  • the screen is advantageously formed by a grill, for example of woven refractory metal wire and the emission plate is a ceramic plate through which are drilled holes enabling gases to pass from the mixing chamber to the outer surface of the emission plate.
  • the ceramic plate may have grooved outer surface for increasing radiation.
  • FIG. 1 is a perspective view of a burner according to the invention, with partial removal of some parts for clarity;
  • FIG. 2 is a section along line IIII in FIG. 1;
  • FIG. 3 is a section along line III-III in FIG. 1;
  • FIGS. 4 to 6 are graphs showing the results of tests on burners according to the present invention.
  • the burner shown in the drawings consists of a hollow box 1 providing a mixing chamber 2 for smoothing out the combustion process.
  • This box 1 has an inlet or sleeve 3 fixed to its base by which the combustible mixture enters box 1.
  • the sleeve is connected to a supply installation (not shown).
  • Sleeve 3 is also provided with a flange 4 enabling the burner to be fixed to a support (not shown).
  • the box 1 is flared in a direction away from sleeve 3 and at its larger end has a downwardly extending peripheral skirt 5 on which a first frame 6 is mounted, the frame 6 retaining in position an emission plate 7 which, in the example shown, is made up of an assembly of ceramic plates through which are drilled passages 8, only a few of which are shown.
  • Frame 6 has an upper edge 9 resting on the periphery of plate 7 and on which in turn rests a flange 10 of a second perimetrical frame 11 on which an anticonvection grill 12 is supported.
  • the grill 12 is made of woven refractory metal wire. It may alternatively be made of punched or pierced expanded metal. The lateral ends of the wires in this grill are turned over at 13 to restrict the movement of the grill on its frame 1 1.
  • a third frame 14 encloses all the elements described above and is fixed to the first frame 6 and to the skirt 5.
  • the frames 6, 11 and 14 are assembled in air-tight fashion so as to be sealed against the entry of any secondary air.
  • auxiliary emission panel 15 consisting of a sheet of refractory metal, through which a large number of holes 16 are drilled, is placed between grill 12 and emission plate 7. This panel is so supported on lugs 17 and 18 fast with frame 11 that it is free to expand relative to frame 11. A space 19 is provided between panel 15 and emission plate 7 and a space 20 is provided between panel 15 and grill 1'2.
  • the distance between plate 7 and panel 15 is approximately double that between panel 15 and grill 12.
  • both may advantageously be made convex, the convexity of panel and grill being outwardly directed.
  • the passages 8 provided in the ceramic plate 7 advantageously have a diameter of between 0,40 and 0,70mm and may open into grooves 8' (see FIG. 2), which may be 1,5 to 2,5mm wide and from I to 3mm deep, on the outer face of plate 7.
  • Such an arrangement has the advantage of preventing any flash-back in the combustion chamber and of localising the flames in grooves 8 over a wide operating range of the burner.
  • the heat transfer between the flame and the ceramic body is thus increased, as is the emissive power of the latter which tends to create an artificial black body because of the length to diameter ratio of each of the orifices.
  • Holes 16 in panel 15 allow the products of combustion to pass through the panel and the ratio between the solid and hollow parts is such that the panel provides a very small heat loss when compared with the emission plate 7.
  • Grill 12 as well as panel 15 are not positively fixed in place so that they can expand freely and frame 1 1 is advantageously made of refractory metal insulated from plate 7 by a band of insulating material (not shown).
  • the radiant anti-convection grill 12 limits heat losses by convection from panel 15 to the outside, it enables the temperature of equilibrium of the latter, both faces of which can reach a temperature of equilibrium extremely close to that of ceramic plate 7, to be raised.
  • the very low thermal inertia of the burner which enables normal operating temperature to be reached in a few minutes, added to the flexibility of operation permitted by the combination of plate 7, panel 15 and grill l2, enables this burner to be adapted to groups of industrial processes requiring modulated or continuous emission of thermal energy.
  • the emission plate 7 is approximately 200mm long by 135mm wide and the auxiliary emission plate 15 is 190mm by 125mm and 4mm thick; the holes drilled in plate 15 are 6mm diameter, evenly distributed in such a way that the solid/hollow ratio is approximately 2.
  • the distance of auxiliary emission plate 15 from emission plate 7 is approximately 13mm round the periphery of emission plate 15 and approximately 20mm in the centre, and the distance between grill 12 and auxiliary emission plate 15 is approximately 8mm. Naturally these dimensions could be modified depending on various factors. Thus, the distances separating the auxiliary emission plate 15 from the emission plate 7 on the one hand and from the grill on the other hand could vary within a margin of: 10 percent.
  • FIG. 4 Solid/hollow ratio A A 3.31 B B 1.98 C C 1.20 D D 0.73
  • auxiliary emission plate is located between two superimposed chambers inside which constant thermal exchanges take place between:
  • auxiliary emission plate As the auxiliary emission plate is not in direct contact with ambient air, both its sides are at practically the same temperature and there is thus a negligeable loss of heat in relation to the lost heat from the emission plate.
  • the burner may be operated with various types of combustion gas and liquid mixture and is easy to use industrially, eg. in ovens, drying machines, etc.
  • a box having an inlet for said gaseous mixture and constituting a mixing chamber
  • said emission plate opposite to said inlet and delimiting said mixing chamber, said emission plate being constituted by ceramic solid plates drilled of passages having a diameter of between 0.40 to 0.70 mm., said passage being adapted to permit flowing of the gaseous mixture therethrough;
  • an auxiliary emission means made of a refractory metal drilled with holes of a larger diameter than the passages in said emission plate, said auxiliary emission means surmounting said emission plate and being spaced from the latter by a peripheral frame supported by said box;
  • a burner according to claim 1 wherein said peripheral frame supporting said auxiliary emission means has an internal seating structure on which is freely seated said auxiliary emission plate so as to allow dilatation of the latter.
  • a burner according to claim 1 wherein on the surface of the ceramic solid plate facing said auxiliary emission means are provided grooves, said passages in said ceramic plates opening in said grooves.
