Definitions

  • the invention relates to a glow plug for a device for firing heavy ceramics, in particular bricks, with a connecting pipe for the intermittent supply of solid fuel by compressed air, a cylindrical pipe end piece with a larger diameter and a baffle plate at the outlet end that forms at least two outlet openings.
  • Such an ignition glow head is already known from DE-PS No. 2441680.
  • the distribution of the ejected solid fuel only in one direction is not given.
  • the danger of the ignition head being destroyed by the explosions occurring is also not completely eliminated and, finally, it is not possible to adapt the fuel distribution to different furnace conditions.
  • the invention has for its object to improve the known ignition glow head in such a way that improved fuel ejection in desired directions and the risk of destruction or damage to the ignition glow head due to the explosions occurring is avoided.
  • the ignition glow head is equipped with non-return chambers means that even strong explosions can be controlled safely.
  • the opposing outlet openings with their steering surfaces and steering chambers ensure a more targeted ejection of the granulated solid fuel.
  • the inserts enable simple and rapid adaptation of the firing process to different firing conditions, e.g. Oven cross sections and the like.
  • the ignition areas for the fuel are considerably enlarged, so that a more effective explosion can be achieved.
  • the ignition glow plug 1 shown in Fig. 1 has a cylindrical connecting pipe 2, via which the ignition glow head can be connected to a supply device which intermittently releases solid fuel, e.g. in the form of ground coal, using compressed air.
  • solid fuel e.g. in the form of ground coal
  • the amount of fuel and compressed air supplied are dimensioned such that an explosion occurs in the ignition glow plug, by means of which the solid fuel particles are thrown out of the ignition glow plug and distributed over the cross section of the furnace.
  • plates 5, 6 protrude toward the outlet end over the lower edge 6 of the pipe end piece 3 and form the transverse baffle plate 10.
  • plates 5, 6 and baffle plate 10 are formed from a one-piece, U-shaped part.
  • baffle plate 10 and the plates 5, 6 together with the pipe end piece 3 form lateral, opposite outlet openings 11, 12.
  • the plates 5, 6 protruding beyond the edge 9 have through openings 13, 14 offset with respect to one another and to the longitudinal center plane.
  • transverse webs 15, 16 which extend transversely to the longitudinal axis of the tube and leave the through openings 13, 14 free.
  • the crossbar ends 17, 18 protrude on both sides preferably equally far over the plates 5, 6 and the equally wide baffle plate 10. They thus form lateral boundaries and steering surfaces to the outlet openings 11, 12.
  • Deflection plates 19, 20 are fastened opposite one another at the lower edge 9 of the pipe end piece 3.
  • the part protruding up to the height of the baffle plate 10 is curved. Staggered longitudinal edges of these deflection plates are welded to the crosspieces 15, 16, while the others end at a distance from the crosspieces 15, 16.
  • the deflection chambers 21, 22 are open downwards and on opposite sides via the outlet openings 23, 24. As a result, the fuel can be distributed over the central area of the furnace. To stand up these deflection chambers 21, 22 with the chambers 8 in connection.
  • the baffle plate 10 has a central opening 25 into which a flat retaining pin 26 of an insert plate 27 or a U-shaped insert 28 can be inserted.
  • the plates or U-shaped inserts 27, 28 fit between the plates 5, 6 and have their ends above the baffle plate te 10 before.
  • By inserting one or more plate-shaped inserts 27, the height of the outlet openings 11, 12, 13 and 14 can be changed. This makes it possible to adapt the fuel distribution to different furnace dimensions or fire conditions.
  • the free passage cross section of the passage openings 13, 14 can be changed by the U-shaped insert 28 by means of the raised edges 29, 30.
  • U-shaped and plate-shaped inserts can also be combined.
  • Glow plug and inserts are made of highly heat-resistant metal, especially steel.
