Definitions

  • the invention relates to a method for controlling the air ratio one with a fan and with a gas control valve provided at least partially premixing, preferably fully premixing Gas burner, with ionization signals in the flame area measured with the help of an ionization electrode the fan speed is recorded from the current Ionization signal representative of the current air ratio first signal derived and this with a predetermined Setpoint is compared, the fan speed at the derivation of the first signal and / or the selection the target value is taken into account and from the comparison a control signal for the gas control valve is derived.
  • the air ratio control of gas burners is becoming increasingly important in practice. With the help of the air ratio control it is possible to operate gas burners in the optimal working range, in which the pollutant emissions, in particular the CO and NO X emissions, are low, the thermal load on the gas burner is very even and both the combustion behavior and the efficiency of the gas burner are optimal. It has been found that the optimal working range for an air ratio is between 1.15 and 1.3. An air ratio control can also reduce the susceptibility of the gas burner to malfunctions and ensure safe and quiet operation of the burner.
  • Air ratio control instead of a one-time air number setting, there is one Air ratio control required because the composition of the fuel gas supplied by the supply network fluctuate greatly can.
  • the gas quality fluctuates accordingly, especially the Wobbe index of the fuel gas. If the gas quality of the fuel gas changes, it takes effect the air ratio control and changes the gas supply with the help of the gas control valve such that the gas burner continues works at the desired air ratio.
  • the air ratio can be adjusted using the various measured variables can be determined. However, it has proven, the air ratio over that with the help of an ionization electrode to determine the detected ionization signal (cf. DE 196 27 857 C2).
  • the ionization electrode provides one stable, easy to maintain and at the same time inexpensive Air number sensor, which is also extremely low Effort can be installed, provided that it is not already available Flame monitoring is already in place. Also allowed the ionization signal is a very reliable and accurate determination the air ratio.
  • the fan speed Since the fan speed is known, it can be derived from the ionization signal then the current air ratio is determined and with a characteristic of the respective fan speed Characteristic curve can be regulated.
  • a signal representative of the current air ratio be in a certain performance range essentially independent of the burner output is. This has the advantage that the air ratio over this performance range can be regulated with a single characteristic can.
  • the object of the invention is therefore in the aforementioned Procedure for checking the operating status of the To allow gas burner.
  • This object is achieved in that a second signal representative of the current power is detected and compared with a predetermined value , from which comparison information about the Operating state of the gas burner can be derived.
  • the invention is based on the knowledge that if Changes to the supply air or exhaust air system of the gas burner occur, the burner output set via the fan speed no longer corresponds to the actual burner output. In this case, the missing correlation between Fan speed and burner output recorded and be compensated for that another for current performance representative signal is detected. Does that make way for them current performance representative second signal from that for from the set performance, the Gas burner does not have the desired performance.
  • the deviation is one a predetermined maintenance threshold to be activated.
  • a particularly large deviation also engage a shutdown mechanism that the gas burner automatically switches off.
  • the fan speed be varied until the current one Performance representative second signal the specified value corresponds.
  • the gas burner then taking into account the changed correlation between Fan speed and burner output continue to operate become. This way a gas burner can last for a long time Period operated safely and with the desired performance become.
  • a further development of the invention is characterized in that that for comparison with the second signal first signal is used as a predetermined value.
  • Power consumption is advantageously used as the second signal of the fan or the temperature level of the Boiler or the air mass flow through the fan is detected.
  • a particularly preferred alternative embodiment is characterized in that the second signal is off a current ionization signal is derived, the second signal for both the current power and for the current air ratio is representative.
  • This embodiment is based on the knowledge that the ionization signal even used to check current performance can be. Since the ionization signal depends on the power is the current operating performance according to customer needs checked in a very wide performance range become. If the derived from the ionization signal for the current air ratio and the current performance representative second signal from that for this air ratio and the gas burner produces this value not the desired performance. It can then do the necessary Steps are initiated.
  • a further development of the invention is characterized in that that also as the first signal for both the current Performance as well as representative for the current air ratio Signal is used, the first and the second Signal a different dependency on the air ratio and / or the performance.
  • the ionization signals themselves first and / or second signal can be used.
  • the method according to the invention is particularly simple by realizing that the current ionization signal, from which the first signal is derived with the help a first supply voltage is measured, and the current one Ionization signal from which the second signal is derived is measured using a second supply voltage.
  • the ionization signals are thereby advantageously measured that an AC voltage, preferably of 230V, is applied to the ionization electrode.
  • the polarity effect the flame causes only one half-wave at a time an ionization current flows. This allows a direct component of the tapped voltage, the ionization signal deduce.
  • An ionization signal measured in this way can be evaluated particularly reliably and precisely.
  • the signal is usually used for evaluation first applied to a low pass filter.
  • the ionization signals can be measured in this way be that a delta voltage or a square wave voltage is applied to the ionization electrode.
  • the ionization signal to determine the representative of the current air ratio Signal using an AC voltage and the ionization signal to determine the current Air ratio and representative of the current performance Signal using a triangular voltage or a square wave voltage be measured or vice versa.
  • the ionization signals are preferably alternated to derive the first signal and to derive the second Signals used.
  • the gas burner can operate in the long term in the optimal operating range be kept that the second signal in regular Intervals, e.g. B. once per minute becomes.
  • the Start of operation of the gas burner Reference measurements carried out be where reference signals for different powers and recorded different air numbers and these as a predetermined Value saved for comparison with the second signal become. If the second signal from a current Ionization signal is derived at the start of operation of the gas burner preferably reference measurements performed where reference ionization signals for different Fan speeds and various air numbers recorded and this as a given value for comparison with the second value.
  • Fig. 1 shows a diagram in which the voltage of a Measurement signal is plotted against the air ratio ⁇ .
  • There are six different measurement signal curves are shown. With those with Signal-designated measurement signal curves are the signals representative of the current air ratio. This were measured from an AC voltage of 230V Ionization signal and the fan speed using a special evaluation circuit derived. The signals are shown for different services. As can be seen, the curves are almost completely on top of each other, i. H. this Signals are actually independent of performance.
  • the measurement signal curves labeled Signal2 are concerned it is for the current air ratio and the current Performance representative signals.
  • the voltage differences between the measurement signal curves are at a given air ratio in the lower Performance range particularly large.
  • a very large one Power range of the gas burner reliably monitored be that the air ratio control in normal operation with With the help of the superimposed signal characteristics and to check the performance the AC voltage of 230V applied to the ionization electrode and the special one Evaluation circuit is bypassed.
  • FIG. 2 shows two diagrams in which the ionization signal is plotted against the fan speed for a second exemplary embodiment of the invention.
  • the measured values shown were recorded at a constant air ratio ⁇ of 1.3.
  • the ionization signals are shown with a supply voltage of 50V and 230V for the ionization electrode.
  • the upper diagram illustrates the normal operating status of the boiler.
  • the set gas supply results in a speed of 2000min. -1 an ionization signal at a supply voltage of 50V of 109. This is the setpoint for regulating the air ratio of 1.3.
  • the supply voltage of the ionization electrode is switched to the control voltage of 230V at regular intervals.
  • the ionization signal is only approximately 102.
  • the difference between the two signals is therefore approximately 7.
  • the difference between these two determined ionization signal values is in the range of 7, the operation of the gas burner is in the optimal working range secured.
  • the ionization signal by applying a Voltage of any shape to the ionization electrode be recorded.
  • the ionization signal can be used in the same way a DC voltage can be measured.
  • For sampling the ionization signal from the ionization electrode can be used to discharge representative of the current air ratio Signal and des for the current air ratio and the current Performance of representative signals of the same sensor be used.
  • two sensors can be used be assigned to the ionization electrode or in Flame area of the gas burner even two separate ionization electrodes to be ordered. After all, they can Reference measurements instead of before starting operation be carried out by the manufacturer.
