Definitions

  • the present invention relates to a measuring device for a flame according to claim 1.
  • the invention also relates to a control device for a burner with the measuring device for a flame according to claim 1.
  • the present invention has for its object to provide a measuring device for a flame of the type mentioned, which allows a more accurate and improved signal evaluation.
  • the alternating component influenced by the flame signal can be separated from the direct voltage component via first means and the separate alternating component can be compared to the separated direct voltage component via second means in order to generate a pulse-width-modulated signal.
  • adjustable signal range in a wide range, the high sensitivity and the large signal-to-noise ratio whether the flame is on or off and that the analog signal is very accurate and reproducible.
  • the signal transmission via an optocoupler is possible, with both information, flame on and off and PWM signal can be transmitted via only one optocoupler.
  • the ionization electrode can be made touch-proof.
  • Fig. 1 shows schematically the principle of operation of the inventive circuit.
  • the flame 14 with ionization electrode 15 shown in FIG. 2 is represented by a diode 1a and a resistor 1b.
  • an AC voltage of, for example, 230V is applied.
  • U B a positive DC voltage
  • the flame resistance 1b also influences the alternating current through the decoupling resistor 4, but to varying degrees compared to the direct current.
  • the resistor 4 thus flows a direct current and an alternating current as described above.
  • the resistor 4 is now followed by a high pass 5 and a low pass 6.
  • the high-pass 5 the alternating current is filtered out and blocked the DC component. Due to the low-pass filter, the DC component dependent on the flame resistance 1b is filtered out and the alternating current is essentially blocked.
  • the alternating current flowing from the high-pass filter 5 is amplified and a reference voltage U Ref is added.
  • the direct current flowing from the high-pass filter 6 is amplified with possibly small alternating current components and a reference voltage U Ref is added.
  • the DC voltage component U is compared in a comparator 10 with the reference voltage U Ref .
  • Both signals, the PWM signal and the flame signal can now be further processed separately or linked by means of an OR gate 12.
  • an OR gate 12 As an output of the OR gate 12, if there is a flame, a PWM signal is shown whose duty cycle is a measure of the flame resistance 1b. If no flame is present, the output of the OR gate is permanently at 1.
  • the PWM signal can be transmitted via an optocoupler, not shown, in order to achieve a protective separation between the mains side and the protective low voltage side.
  • FIG. 2 shows the actual structure of the diode 1a shown in FIG. 1 as an equivalent circuit 1 and of the resistor 1b, as is also known, for example, from DE 196 32 983 A1.
  • a burner 13 By a burner 13, a flame 14 can be generated. In the flame area 14 protrudes an ionization electrode 15 which detects the ionization current. This depends on the flame resistance and thus the electrode temperature. The electrode temperature in turn depends on the lambda value and thus the excess air of the mixture to be burned. By means of the lambda value, the ratio of air to gas can be adjusted. Typically, the lambda value is chosen between 1.15 and 1.3 to achieve a higher than stoichiometric air to gas ratio
