Definitions

  • the invention relates to a flame monitoring device with a voltage generating and measuring arrangement according to the preamble of claim 1 and a method for monitoring a burner by means of a flame monitoring device according to the preamble of claim 10.
  • a flame monitoring device is known with a voltage generating and measuring arrangement in which an air-gas ratio of a burner flame is controlled via an ionization electrode.
  • Ionization electrodes are often used to monitor a gas flame and use the rectifying property of the gas flame. For this purpose, an alternating voltage is applied to the ionization electrode and an ionization current is measured at the ionization electrode. If there is no flame or the flame is extinguished, the ionization current stops, allowing the flow of gas to be shut off to prevent the risk of unburned, escaping gas. While such a safety monitoring requires only a binary output signal is in the DE 100 25 769 A1 proposed to use a dynamic feedback of the ionization electrode for controlling the flame characteristics, in particular for controlling the air / fuel ratio.

Furthermore, the flame monitoring device comprises a control unit for controlling the voltage generating unit and for evaluating the measured values of the measuring unit.
  • control unit is designed to detect at least one dynamic feedback of the voltage generating and measuring arrangement and to evaluate it for detecting a malfunction of an element of the voltage generating and measuring arrangement.
  • Safety-relevant components or assemblies of the voltage generating and measuring arrangement should be referred to as elements of the voltage generating and measuring arrangement.
  • the voltage generating unit, the ionization electrode, the ignition device and the measuring unit come into consideration as elements to be monitored.
  • the dynamic feedback of the voltage generating and measuring arrangement is used for monitoring the same, so that a reliability of a burner with a generic flame monitoring device can be significantly increased.
  • dynamic feedback is to be understood as meaning, in particular, a time-dependent signal having a continuous or quasi-continuous value range which is a parameter for a voltage or a current in the voltage generation and power supply Measuring arrangement forms.
  • the control unit which forms from the dynamic feedback a parameter for an actually applied ignition voltage, or that the dynamic feedback is such a parameter.
  • the dynamic feedback may be directly proportional to the actual applied ignition voltage or may be a digital signal that encodes a measured ignition voltage.
  • a technically simple evaluation of the dynamic feedback can be made possible if the dynamic feedback is a pulse-width-modulated signal in which a duty cycle codes the actually applied ignition voltage.
  • the actual applied ignition voltage can be tapped by means of a voltage measuring arrangement on an ignition coil of the ignition device.
  • the dynamic feedback forms a parameter for an actually applied ionization voltage.
  • the ionization voltage can be monitored and measuring errors of the measuring unit, which are caused by an incorrectly determined ionization voltage, can be avoided.
  • the voltage generating unit comprises a variable voltage source for generating both the ignition voltage and the ionization voltage
  • the voltage generating unit comprises a variable voltage source for generating both the ignition voltage and the ionization voltage

  • control unit is designed to receive and process the dynamic feedback in the form of a pulse-width-modulated signal, the evaluation can be carried out by means of a simple low-pass filter and information loss during transmission can be largely avoided.
  • Quiet continuous operation can be achieved by a current regulator for generating a stable ionization voltage can be achieved.
  • control unit is designed to detect at least a first dynamic feedback of the voltage generating unit and a second dynamic feedback of the measuring unit and to use for detecting a malfunction of the voltage generating unit or the measuring unit.
  • the invention relates to a method for monitoring a burner by means of a flame monitoring device, wherein the flame is monitored by means of a Ionisationsstrom generated by an ionization electrode.
  • a dynamic response of the flame monitoring device is detected and a malfunction of at least one element of the flame monitoring device is detected as a function of the dynamic feedback.
  • FIG. 1 schematically shows a flame monitoring device for monitoring a burner 22 with a voltage generating and measuring arrangement 10.
  • the voltage generating and measuring arrangement 10 comprises a voltage generating unit 12 for generating an ignition voltage, which can be used to operate an ignition device 14 with a firing mass.
  • the voltage generating unit 12 serves to generate a Ionization voltage of an ionization electrode 16 for monitoring a flame 18 of the burner 22.
  • the voltage generating and measuring arrangement 10 comprises a measuring unit 20 for measuring an ionization current generated by the ionization voltage.
  • the ionization voltage is an AC voltage that drops across the flame 18 of the burner 22.
  • the flame 18 is a gas flame and has a rectifying property, since there are 18 carriers of different polarities in the flame, the mobility of which differs greatly.
  • the ionization current from or to the ionization electrode 16 flows predominantly during a half period of the ionization voltage, while the latter has a certain sign.
  • the ionization current also comes to a standstill, which can be measured by the measuring unit 20. If this happens, appropriate safety measures can be taken, for example, the gas supply can be switched off.
  • the evaluation of the signals of the measuring unit 20 and the control of the voltage generating unit 12 takes place in a control unit 24 of the flame monitoring device.
  • the control unit 24 controls the voltage generation unit 12 by means of a first, pulse-width-modulated control signal 26a, which is transmitted via a first signal line 28a from the control unit 24 to the voltage generation unit 12.
  • the control unit 24 transmits a second, pulse-width-modulated control signal 26b to the measuring unit 20 via a second signal line 28b.
  • the second control signal 26b is primarily used to specify a measuring frequency, but can also be used to control operating parameters of the measuring unit 20.
  • the control unit 24 receives a first dynamic feedback 30a from the voltage generating unit 12 of the voltage generating and measuring arrangement 10.
  • the control unit 24 receives a second dynamic feedback 30b from the measuring unit 20.
  • the first dynamic feedback 30a and the second dynamic feedback 30b are each pulse width modulated signals, wherein a duty cycle of the first dynamic feedback 30a and the second dynamic feedback 30b has a continuous range of values and is time-dependent.
  • the value of the duty cycle encodes an actually generated voltage in the voltage generation unit 12 or a voltage measured by the measurement unit 20 or an ionization current measured by the measurement unit 20, as described in greater detail below.
  • the control unit 24 is designed to recognize a malfunction of an element or component of the voltage generating and measuring arrangement 10 from the first dynamic feedback 30a and the second dynamic feedback 30b and to evaluate the first dynamic feedback 30a and the second dynamic feedback 30b.
  • the duty cycle of the first dynamic feedback 30a is a characteristic for an actual applied ignition voltage
  • the duty cycle of the second dynamic response 30b or of the second pulse width modulated signal is a parameter for an ionization voltage actually applied or for an actually flowing ionization current.
  • FIG. 2 shows a circuit diagram of the voltage generating unit 12 from FIG. 1 in a more detailed presentation.
  • the first pulse width modulated control signal 26a of the control unit 24 is applied, which has a carrier frequency of 22 kHz in a preferred embodiment.
  • a second terminal 32b is connected to the third signal line 28a so that the control unit 24 receives the first dynamic feedback 30a via the second terminal 32b.
  • the height of an output voltage at a transformer 34 can be set via the first pulse-width-modulated control signal 26a.
  • the controller 24 may increase the positive duty cycle of the first pulse width modulated control signal 26a to increase the output voltage and power at the transmitter 34. Increasing the duty cycle, the voltage at the transformer 34 increases.
  • the voltage generating unit 12 includes a current regulator 36, which ensures a stable output voltage at the operating point.
  • FIG. 3 shows a circuit diagram of the measuring unit 20 of the voltage generating and measuring arrangement 10 from FIG. 1 in a more detailed view.
  • a first contact point 38a is connected to the ionization electrode 16 such that an ionization current at the contact point 38a generates a pulse width modulated signal forming the second dynamic feedback 30b at two outputs.
  • the size of the duty cycle of the pulse-width-modulated signal generated at the two outputs is a parameter for the ionization current.
  • the voltage generated at the transformer 34 then leads to ignition of the ignition device 14 when it exceeds an ignition voltage.
  • the voltage at the transformer 34 becomes lower, it generates an ionization voltage at the ionization electrode 16 and therefore causes a measurable ionization current to flow in the matrix burner burner 22 when the flame 18 is present.
  • the value of the voltage applied to the transformer 34 therefore decides whether the voltage is used as the ignition voltage or as the ionization voltage. Therefore, the transformer 34 of the voltage generating unit 12 forms a variable voltage source for generating both Ignition voltage and the ionization voltage.
  • the variable voltage source is, as discussed above, adjustable by the choice of frequency and / or by the selection of a duty cycle of the first control signal 26a, 26b.
  • control unit 24 compares the measured value encoded in the second dynamic feedback 30b detected by the measuring unit 20 and the value encoded in the first dynamic feedback 30a in different operating modes having different upper thresholds and lower thresholds. If the measurement or value exceeds the respective upper threshold value or is smaller than the lower threshold value, the control unit 24 generates an error signal and optionally initiates an emergency shutdown of the burner 22.
  • the control unit 24 is a programmable arithmetic unit equipped with software that controls a test operation of the flame monitoring device outside normal operation of the burner 22. In the test mode, the control unit 24 generates and measures an ignition voltage or ionization voltage via the first control signal 26.
  • FIG. 4 shows the time course of the first dynamic feedback 30a of the voltage generating and measuring arrangement 10 in test mode, ie when the fuel supply is switched off, in the case of a short circuit of an ignition electrode. If the ignition electrode is short-circuited, no voltage can build up on the transformer 34 despite the controlled AC voltage, so that the dynamic feedback 30a, 30b assumes a constant value.
  • FIG. 5 shows the output voltage at the transformer 34 and the first dynamic feedback 30a, 30b at normal ignition. It can be seen that the amplitude of the voltage applied to the transformer 34 AC voltage periodically increases to discharge in the ignition when it reaches an ignition threshold.
  • the first dynamic feedback 30a is permanently at about 3 volts, varies during normal ignition the ignition voltage encoded in the first dynamic feedback 30a by about 1.5 volts.
  • the control unit 24 detects in the test mode when the fuel supply is switched off a firing repetition or firing sequence period, in order to draw conclusions about a state of wear of the ignition electrode.
  • FIG. 6 shows an example of a firing order in which a firing sequence period is 145 ms.
  • FIG. 7 shows a firing order in which a firing frequency is 156 ms.
  • the connection to the ignition electrode is interrupted or the distance of the ignition electrode to the ignition mass has exceeded a permissible value, this can be detected by an evaluation of the first dynamic feedback signal.
  • the ignition sequence is shortened if there is an interruption or an impermissible distance.
  • FIG. 8 shows a recorded in a test operation of the control unit 24 course of the measurement signals in the event of failure of a defective voltage generating unit 12 and a defective ignition device 14. Although the output voltage at the transformer 34 reaches the required ignition threshold, a firing order is not recognizable.
  • FIG. 9 finally shows a dynamic feedback 30a, 30b of the voltage generating and measuring arrangement 10 in the event of a short circuit of Ionization electrode 16.
  • the output voltage at the transformer 34 does not reach its normal value, which can also be recognized by the first dynamic feedback 30a, 30b.
  • the measurement or the verification of the short circuit of the ionization electrode 16 can be carried out in particular even when the burner 22 is switched on.
  • the control unit 24 compares a value of the ionization voltage detected via the first dynamic feedback 30a, 30b during normal operation with a predetermined, stored value which corresponds to an ionization voltage immediately after the production of the ionization electrode 16 or the flame monitoring device.
  • a gradual deterioration or wear of the ionization electrode 16 can be recognized by a slow drop in the ionization voltage detected via the first dynamic feedback 30a, 30b.
  • a warning signal is generated by the control unit 24 when the ionization voltage detected via the first dynamic feedback 30a, 30b falls below a critical value. The user is prompted by the warning signal to replace the ionization electrode 16. Alternatively, when the same or a second threshold is reached, an emergency shutdown of the burner 22 may occur.
