Definitions

  • the invention relates to a ceramic burner head with slit-shaped flow channels for fuel and oxidizing agent which are guided parallel to one another to the burner mouth and which are arranged adjacent to one another and have partition walls made of porous material permeable to the fuel between them in the region of the burner mouth.
  • the invention is based on a burner head as described in EP-A-17 156. This document falls under EPC Art. 54 (3).
  • Ceramic burner heads of this type are intended for use in industrial furnaces as well as for heat units. They are suitable for gaseous but also liquid fuels.
  • liquid fuels When using liquid fuels, the fuel is evaporated before it exits the burner mouth by preheating the oxidizing agent and corresponding heat exchange between the oxidizing agent and the liquid fuel in the flow channels in the ceramic burner head.
  • the liquid fuel penetrates the porous partition walls between the flow channels in the area of the burner mouth and is taken up by the preheated combustion air. Due to the evaporation of the liquid fuel on the surface of the porous walls, an undesirable overheating of the fuel, which leads to cracking, is prevented.
  • fuel and combustion air are mixed together and led to the burner mouth as an ignitable mixture.
  • the object of the invention is to simplify the design of the burner head with porous partition walls between the flow channels for oxidizing agent and fuel in the area of the burner mouth.
  • a mouthpiece is inserted on the burner mouth that forms the partitions and for this purpose consists of porous material which is permeable to the fuel.
  • the mouthpiece is embedded in outer walls which run in the direction of flow of the oxidizing agent and are not permeable to the oxidizing agent.
  • the mouthpiece can advantageously be formed independently of the configuration of the flow channels carrying the oxidizing agent and fuel and can be adapted to the desired shape of the mouths of the flow channels, which shape is appropriate for the particular purpose of the burner head.
  • the mouthpiece is arranged in the burner head at a distance from the downstream end of the flow channels for the oxidizing agent.
  • the burner head has slot-shaped flow channels 1, 2 for fuel and oxidizing agent which are guided parallel to one another.
  • preheated combustion air is conducted in flow channel 1 and fuel is conducted in flow channel 2.
  • Gaseous or liquid fuels can be used.
  • the flow channels 2 for the fuel are closed at the burner mouth 3 with end pieces 4.
  • a mouthpiece 5 is used on the burner mouth, which consists of porous material which is permeable to the fuel.
  • the mouthpiece is embedded in outer walls 6, 7, 8, 9.
  • the outer walls extend parallel to the direction of flow of the oxidizing agent and consist of a material that is impermeable to the oxidizing agent.
  • the direction of flow of the oxidizing agent is indicated in Fig. 2 by an arrow drawn with dashed lines.
  • a recess 10 is provided in the outer wall 9, through which the fuel which is guided in a channel 11 in the ceiling part 12 of the ceramic burner head can flow into the flow channels 2 of the mouthpiece 5.
  • Combustion air is supplied to the ceramic burner head as an oxidizing agent through flow channels 1 '.
  • the flow channels 1 ' form the part of a countercurrent heat exchanger in which the combustion air is preheated.
  • Exhaust gas is advantageously used for preheating, which is guided in the counterflow heat exchanger in exhaust gas channels which run parallel to the flow channels 1 'and are not shown in the drawing.
  • the exhaust gas is introduced in the counterflow heat exchanger at the inlet 13.
  • the mouthpiece 5 is arranged at a distance 14 from the downstream end of the flow channels 1 'in the ceramic burner head.
  • the distance is a multiple of the slot width of the flow channels 1 'in order to even out the flow of the combustion air to the burner mouth in the space 15 thus created between the end of the flow channels 1' and the adjoining mouthpiece 5.
  • the fuel channels 2 in the mouthpiece 5 are closed towards the space 15 by end pieces 16.
  • the fuel flowing into the flow channels 2 passes through the porous walls of the mouthpiece 5 into the flow channels 1 and mixes with the preheated combustion air flowing there to form an ignitable mixture, which leads to the burner mouth 3 and is ignited in the combustion chamber.
  • the mouthpiece is inserted in the outer walls 6, 7, 8, 9 with slip mass.
  • the ceramic burner head is re-fired for a gas-tight connection of the mouthpiece to the outer walls.
