Definitions

  • the invention relates to a device for flame monitoring of oil burners, in particular of yellow or blue burning oil burners, comprising a flame sensor detecting the illuminance in the combustion chamber and a monitoring circuit controlling the fuel supply as a function of the detected illuminance with a light threshold for the startup phase of the oil burner, above which an error message takes place, and with a higher than the light threshold dark threshold for the stabilization and operating phase of the oil burner, below which an error message occurs.
  • the European standard EN 230 allows the use of flame sensors (flame sensors) for monitoring oil burners, which have an illuminance of at least 1 lx (lux) in the visible range. Furthermore, the standard requires a "negative switching difference", ie the bright message before fuel-free (extraneous light) must be given at lower illuminance levels than a dark message when the flame goes out during operation (flame failure).
  • the illuminance detected by a flame sensor in the combustion chamber must not exceed the light threshold B max (I), otherwise the fuel supply is stopped.
  • the safety phase II following the start-up phase is the maximum time from when the fuel valves are opened, during which fuel can flow into the combustion chamber without the formation of a flame.
  • the detected illuminance must not fall below the dark threshold B m j_ n (III, IV) (> B max (D) occurring in the event of a flame failure, otherwise the fuel supply is stopped.
  • Yellow-burning oil burners have a high lighting intensity in the visible range.
  • Blue-burning oil burners blue burners
  • the different courses of the illuminance for yellow burners (a) and blue burners (B) are shown in FIG. 2.
  • Another problem can be short-circuits on the conductor tracks of the burner control, short-circuits in the supply lines to the flame monitor or other short-circuits that can occur during operation with a flame. With such a short circuit, it is not possible to register a flame failure.
  • this object is achieved in that the dark threshold during the stabilization phase is higher than the dark threshold during the subsequent operating phase.
  • the higher dark threshold was introduced during the stabilization phase or after the safety phase, so that increased illuminance is required during the stabilization phase. Since a blue burner starts up as a yellow burner and is only driven into the blue area during operation, an increased lighting signal is also available during the stabilization phase. The requirement of increased illuminance during the stabilization phase or after the safety time also reduces the risk of short circuits with contact resistance.
  • the dark threshold during the stabilization phase is chosen to be higher than the illuminance during its operating phase. Low illuminance is required during operation to ensure safe operation for blue burners.
  • the monitoring circuit has, at least for the operating phase, a maximum light threshold above the dark threshold, above which the fuel supply is interrupted.
  • This maximum light threshold is preferably also provided for the stabilization phase and for a safety phase provided between the start-up phase and the stabilization phase.
  • the conventional monitoring process was supplemented by an additional maximum light threshold for short-circuit detection (low-impedance short-circuits).
  • the short-circuit detection can rule out the case of an undetected flame simulation (eg due to a fuel valve, a defective flame monitor lead, etc.).
  • the monitoring circuit according to the invention can be implemented, for example, by means of hardware with different switching thresholds or by means of analog value detection with definition of different switching thresholds via software.
  • the invention also relates to corresponding monitoring methods and automatic firing systems which work or are equipped with such a flame monitoring device.

  • Flame monitoring device with schematically indicated temporal courses of the illuminance of yellow (a) and for blue (b) burning oil burners;
  • Fig. 2 is a monitoring diagram of a conventional monitoring with schematically indicated temporal profiles of the illuminance of yellow (a) and for blue (b) burning oil burners.
  • the evaluation of the flame signal is changed in the monitoring diagram according to FIG. 1.
  • the monitoring diagram shown in FIG. 2 was achieved by an additional maximum light threshold B max for short-circuit detection (low-impedance short circuits) during the safety, stabilization and operating phases II, III, IV and by a higher dark threshold B m -j_ during stabilization phase III.
  • n (III) added for increased illuminance.
  • the short-circuit detection can rule out the case of a flame simulation.
  • an illuminance becomes higher than B m; y_ n (III) required. Since a blue burner starts to ignite as a yellow burner and is only driven into the blue area during operation, an increased lighting signal is also present during stabilization phase III.
  • the dark threshold B mj _ n (IV) is then lowered in order to also permit lower illuminance and thus to ensure safe operation for blue burners.
  • the requirement of an increased illuminance B m -j_ n (III) after the safety time II reduces the risk of short circuits with contact resistance.
  • the monitoring diagram shown in FIG. 1 thus offers the following advantages:
  • Short circuits during the operating times with flame formation i.e. during the stabilization phase III and the operating phase IV, are reliably recognized.
  • a single flame sensor type LDR (light depending resistor) can be used for yellow and blue burners, which increases efficiency.
  • the LDR can instead the commonly used IRD (infrared flicker detector), which is much more expensive than the LDR.

Abstract

L'invention concerne un dispositif pour le contrôle de flamme de brûleurs à mazout, en particulier de brûleurs à flamme jaune ou à flamme bleue, comprenant un détecteur de flamme détectant l'intensité lumineuse dans l'espace de combustion, et une connexion de contrôle commandant l'amenée de combustible en fonction de l'intensité lumineuse détectée, avec un seuil de clarté (Bmax(I)) pour la phase de démarrage (I) du brûleur, au-dessus duquel on a émission d'un signal d'erreur, et avec un seuil sombre (Bmin(III, IV) supérieur au seuil de clarté (Bmax(I)) pour la phase de stabilisation et de fonctionnement (III, IV) du brûleur, au-dessous duquel on a émission d'un signal d'erreur. Le seuil sombre (Bmin(III) pendant la phase de stabilisation (III) est plus élevé que le seuil sombre (Bmin(IV)) pendant la phase e fonctionnement subséquente (IV). On peut ainsi utiliser le même détecteur de flamme pour les brûleurs à flamme jaune et à flamme bleue.
