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 is based on the object of a measuring device for a flame to provide the type mentioned above, which is more accurate and improved Signal evaluation enabled.
  • the essence of the invention is therefore that the alternating component influenced by the flame signal exceeds the first means can be separated from the DC voltage component and the separated AC component with the separated DC voltage component is comparable by a second means generate pulse width modulated signal.
  • Fig. 1 shows schematically the principle of operation of the circuit according to the invention.
  • the flame 14 shown in FIG. 2 with the ionization electrode 15 is represented by a diode 1a and a resistor 1b.
  • An AC voltage of, for example, 230V is applied via L and N. If a flame is present, a larger current flows through the block capacitor 3 in the positive half-wave than in the negative half-wave due to the flame diode la. This forms a positive DC voltage U B at the block capacitor 3 between L and a resistor 2 attached for the purpose of protection against contact.
  • a decoupling resistor 4 therefore flows a direct current from N to the block capacitor 3. The level of the direct current depends on U B and thus directly on the flame resistance 1b.
  • the flame resistor 1b also influences the alternating current through the decoupling resistor 4, but to a different degree compared to the direct current.
  • a direct current and an alternating current thus flow through the resistor 4 as described above.
  • the resistor 4 is now followed by a high pass 5 and a low pass 6.
  • the high-pass filter 5 filters out the alternating current and blocks the direct-current component.
  • the low-pass filter filters out the DC component, which is dependent on the flame resistance 1b, and essentially blocks the AC current.
  • the alternating current flowing from the high pass 5 is amplified in an amplifier 7 and a reference voltage U Ref is added.
  • the direct current flowing out of the high pass 6 is amplified with possibly small alternating current components and a reference voltage U Ref is added.
  • the retriggerable monoflop 11 thus forms a "missing pulse detector" which is the dynamic on - / off signal converted into a static on / off signal.
  • Both signals, the PWM signal and the flame signal can now be processed separately are or can be linked by an OR gate 12.
  • the pulse duty factor of which is a measure for the flame resistance is 1b. If there is no flame, the output of the OR gate is permanent at 1.
  • the PWM signal can be via an optocoupler, not shown be transferred to a protective separation between the network side and the To reach the protective extra-low voltage side.
  • Figure 2 shows the actual structure of the diode shown in Figure 1 as an equivalent circuit 1 1a and the resistor 1b, as is also known for example from DE 196 32 983 A1.
  • a flame 14 can be generated by a burner 13.
  • Ionization electrode 15 which detects the ionization current. This depends on Flame resistance and thus the electrode temperature.
  • the electrode temperature in turn depends on the lambda value and thus the excess air of the one to be burned Mix off.
  • the ratio of air to gas can be set using the lambda value become.
  • the lambda value between 1.15 and 1.3 is chosen to be a to achieve super-stoichiometric ratio of air to gas
