Definitions

  • the invention relates to a method for fuel gas-air adjustment for a fuel gas burner.
  • the fuel gas to air ratio of a fuel gas burner can be adjusted by measuring the ionization voltage or the ionization current at a monitoring electrode.
  • the EP 770 824 B1 describes a method in which, starting from a superstoichiometric burner operation, the excess air is reduced until there is a slight substoichiometric combustion.
  • the ionization voltage is measured between an ionization electrode and the burner.
  • ⁇ 1.0
  • the ionization voltage is maximal. Consequently, the ionization voltage, starting from superstoichiometric combustion, initially increases in the reduction of the excess air to reach a maximum under stoichiometric combustion.
  • Embodiments of this control method are also known from DE 40 27 090 C2 .
  • US 5,971,745 A discloses a method for adjusting the fuel gas-air mixture by means of ionization current monitoring. Characteristic of this method is that starting from an operating point with excess air, the fuel gas-air mixture is first enriched. As soon as an extreme value (maximum) is found, the enrichment is ended. This can be determined, for example, by measuring a drop again after an increase in the ionization current. Alternatively, this "peak", ie extreme value / maximum can be determined if the gradient of the signal is zero. When the maximum is found, the mixture is emaciated again.
  • DE 20 2004 017 850 U1 shows a gas burner, in which by means of a thermocouple, the flame temperature is measured.
  • the temperature behaves analogous to the ionization according to EP 770 824 B1 ,
  • the mixture is enriched and the flame temperature is measured. If a maximum is measured, then the mixture is defined as emaciated.
  • US 4 118 172 A discloses a calibration method that uses a temperature measurement to detect a maximum at stoichiometry.
  • a disadvantage of such a method is that always a stoichiometric or slightly substoichiometric combustion must be started. This results in substantial amounts of carbon monoxide and nitrogen oxide emissions.
  • EP 1 176 364 A1 It is known that processes with maximum at stoichiometry have the disadvantage that temporarily the burner is operated with high pollutant emissions.
  • the ionization signal is measured at startup, then changed the fuel gas quantity and again measured the ionization signal. From the evaluation of the signal difference, the composition of the fuel gas is inferred and the fuel gas throttle adjusted accordingly.
  • the invention has for its object to provide a method for controlling the fuel gas-air mixture in gas-powered burners by Ionisationsstromunk, which avoids polluting combustion conditions.
  • the object is achieved in that during the operation of the burner, the fuel gas-air mixture is emaciated and in this case the ionization signal is measured continuously. From the ionization signal a gradient is formed during the change. If the gradient exceeds a certain gradient or if the gradient rises disproportionately in comparison to the previous course, then the emaciation is terminated and the fuel gas-air mixture is enriched in a defined manner.
  • the measurement signal is highly dependent on deposits on the electrode as well as the position of the electrode. Therefore, it is not appropriate to use exceeding or falling below a certain absolute value as a relevant event.
  • the sharp increase in the gradient is a sure sign that the flame will soon lift off as the proportion of air increases further.
  • the gradient can be determined by dividing the difference signal of the ionization electrode with the differential speed of the fan motor.
  • a division of the difference signal of the ionization with the difference position of the actuator of a gas valve or a differential time unit can be done.
  • the signal of the ionization electrode can be detected by serially connecting a constant voltage source to the flame of the burner and a resistor, and measuring the voltage drop across the resistor.
  • FIG. 1 shows a burner 1 with blower 8 with blower motor 9 in an air inlet 12.
  • air inlet 12 opens a gas line 13, in which a gas valve 10 with actuator 11 is located.
  • the blower motor 9 and the actuator 11 are connected to a controller 7.
  • the burner 1 is a flame 2, in which an ionization electrode 3 protrudes.
  • the ionization electrode 3 is connected to a voltage source 4. This is connected to its second electrode with a resistor 5, which in turn is connected to the burner 1. Parallel to the resistor 5, a voltmeter 6 is connected, which is connected to the controller 7.
  • the fan 8 sucks in combustion air via the air inlet 12.
  • the speed n of the fan 8 can be adjusted continuously.
  • the gas valve 10 the amount of fuel gas supplied, which flows in via the gas line 13, can be changed continuously; In this case, the number of steps n s of the actuator 11 is detected.
  • fuel gas and air are mixed with each other and ignited at the outlet of the burner 1, so that a flame 2 is formed. Since the ions of the flame 2 are electrically conductive, a current can flow between the ionization electrode 3 and the burner 1. It follows that an electrical voltage U Flame is applied. The flow of ions through the flame 2 ensures that the electrical circuit (burner 1, ionization electrode 3, voltage source 4, resistor 5) is closed.
  • FIG. 2 shows the course of the measured at the resistor 5 voltage U on the air ratio ⁇ and the fan speed n.
  • the burner 1 first runs with a previously unknown excess of air.
  • the speed n of the blower 8 is increased.
  • the air ratio ⁇ increases.
  • the voltage drop U across the resistor 5 is measured continuously over the time t and passed on to the controller 7.
  • the gradient ⁇ U / ⁇ n is calculated, where n is the speed of the fan 8. If the gradient ⁇ U / ⁇ n increases excessively after a certain point, this is an indication that soon the flame will lift off and thus break off.
  • the air ratio ⁇ is then about 1.6. Starting from this point, the rotational speed n of the fan is now deliberately reduced in such a way that an air ratio ⁇ 1.25 is established.
  • a gradient of differential voltage ⁇ U to differential setting position of the actuator ⁇ n S can also be formed if a reduction in the fuel gas quantity is undertaken instead of an increase in the fan speed.
  • a gradient of the time can also be formed with constant emaciation ( ⁇ U ⁇ ) .
  • the operating state where liftoff is imminent may be determined by comparing the current gradient to at least one previous gradient, and in the event the current gradient exceeds the compare value (s) by a certain percentage, the expected state is present. For example, the lowest measured gradient can be used as comparison value. Alternatively, an absolute value can be specified.
  • the time difference or speed difference In order to eliminate the influence of signal noise (fluctuation of the measuring signal by a trend line), the time difference or speed difference must not be selected too small.
  • the voltage of the flame U flame can also be measured directly. In this case, however, the ionization voltage at stoichiometric combustion is maximum and the ionization voltage signal drops as the air ratio is increased.
  • a constant voltage U 0 and a constant current source with a constant current I 0 can be connected to the series circuit of the resistor 5 with the flame. 2 Depending on the flame resistance, a certain voltage sets.
