Definitions

  • the invention relates to a device for monitoring the operation of the burner plate of a surface burner, in particular a radiation burner, penetrated by mixture outlet openings, by means of at least one electrode measuring ionization in the flame area of the burner.
  • a surface burner in particular a radiation burner
  • the mixture of fuel gas and combustion air which is premixed in optimal proportions, is already within the mixture of ceramic material, steel wool or the like.
  • existing burner plate ignited and burns with very short flames, which have a very short reaction time. These flames can be so short that they cannot be seen, but only a glow from the burner plate can be observed.
  • the invention provides according to its most important feature that the electrode measuring the ionization is assigned a limited area of the burner plate is in which the burner flames are dimensioned with a greater length than in the remaining area of the burner plate.
  • the mixture outlet openings in the area assigned to the electrode can be dimensioned with a smaller cross section than the mixture outlet openings passing through the remaining area of the burner plate, so that the mixture flows through these smaller openings more quickly and forms longer burner flames.
  • the proportion of air in the mixture supplied to the burner plate in the area assigned to the electrode can also be deliberately made smaller than in the remaining area of the burner plate. This also increases the length of the burner flames locally.
  • a ceramic burner plate 1 fed from its underside with a gas-air mixture is penetrated by mixture outlet openings 2 and is monitored by two cooperating electrodes 3 measuring the ionization in the distance area, which are located above the burner plate 1 via a Extend surface area 4 of this plate, in which the mixture outlet openings have an approximately half smaller diameter than the mixture outlet openings 2 in the remaining region of the burner plate 1.
  • this region 4 which has the smaller mixture outlet openings 5 can be formed by an insertable part 6 of the top of the burner plate .
  • burner flames are formed in the area 4 in such a way that the two electrodes 3 connected to a current source 7 are able to measure and signal ionization.
  • the burner plate 1 consists of a conductive material, for example steel, steel wool or the like, and is connected to the current source 7 together with the electrode 3.
  • the burner plate 1 is again supplied with a gas-air mixture from below via a mixture guide 8.
  • the combustion air flows to this mixture guide 8 via a combustion air guide 9, in which there is a nozzle head 11 which is formed with radial gas nozzles 10 and is fed with fuel gas via a gas supply line 12.
  • a branch line 13 of this gas supply line 12 opens into a separate mixture guide 14, which supplies only that portion 4 of the burner plate 1 with mixture above which the electrode 3 is located.
  • the proportion of air in this mixture supplied to sub-area 4 is to be dimensioned by dimensioning the branch line 13 and the separate mixture guide 14 in such a way that it is higher in the mixture flowing into the mixture guide 8 than in the separate mixture guide 14.
  • the flames that form at the mixture outlet openings 5 inevitably become longer than those that start at the mixture outlet openings 2.
  • the longer flames enable the electrode 3 to measure the ionization and to display the burner operation.
