Definitions

  • the invention relates to a control device for a burner, which burner in a Flame region of the burner arranged ionization electrode, and an actuator, which is the fuel supply amount or the air supply amount depending on one Control signal influenced.
  • Ionization electrodes have long been used for flame monitoring in burners used.
  • the ratio of the amount of air to the amount of fuel is often Called lambda, for each power requirement either by a controller or by a Control with sensors coordinated.
  • lambda is intended for everyone Power requirement may be slightly above stoichiometric 1, for example 1.3.
  • Air-controlled burners unlike controlled burners, react to external influences which change the combustion. They therefore have a higher efficiency and therefore one higher efficiency as well as lower pollutant emissions and thus a lower one Ecological damage.
  • Rapid changes in the fuel supply or air supply are typically caused by abrupt changes in the power requirement.
  • control devices according to IT-95U000566 and EP-A1-909922 contribute If rapid changes in performance occur, control is based on the stored Characteristic curve, but compensate for their imperfection in that they show the latest status of the Control signal first at a constant distance along the characteristic to a new value move.
  • EP-A2-806610 developed control devices which also have stored a characteristic curve for the control signal.
  • the characteristic curve serves also basically to pre-control the control signal in the event of rapid changes in power, while the ionization current is still lagging behind the facts.
  • the latter control devices include one downstream of the ionization electrode Ionization evaluator, which generates an ionization signal, a control unit in which characteristic data for determining a first behavior of the actuator, which are at least stored temporarily generates a first control signal, and a controller, which the above Control signal at least temporarily depending on the ionization signal and at least temporarily generated depending on the first control signal.
  • Control unit at least temporarily generates a second control signal and the controller that Control signal generated at least temporarily depending on the second control signal.
  • control device can be constructed in such a way that it itself, when detected suitable conditions, an adjustment procedure for the acquisition of new characteristic data is carried out.
  • an occasional or regular recalibration takes place, for any creeping changes in the control system, such as wear or contamination of the Ionization electrode to compensate.
  • the Control characteristics can be determined automatically, even for gases using the preset Characteristic curves are not recorded.
  • the characteristic data can, for example, be used as the constants in a polynomial development up to third order.
  • the one approximately represented by the polynomial development Function defines a relationship between an input parameter and the control signal.
  • the requested power serves as input parameter for the control curves, either in the form of a manipulated variable or a measured variable that corresponds to the power, for example the fan speed.
  • a manipulated variable for example the fan speed.
  • Control curves are used, e.g. B. temperature signals of all kinds such as burner temperature, Flow and return temperature, etc. Further examples are a pressure difference measured value Determination of gas or air volume flow, a gas or air volume flow meter, or directly the control signal for operating a gas valve or an oil pump.
  • the first and the second behavior of the actuator advantageously depend on input parameters which represent the same size.
  • the level of performance requested, or another physical size, the control unit by means of a single input parameter, such as the manipulated variable of the fan speed, or by means of input parameters of different types, such as The manipulated variable and the measured variable of the fan speed are fed.
  • Burners are often equipped with a temperature sensor for the boiler temperature.
  • a Change in the energy content of the fuel supplied has a change in According to boiler temperature.
  • the manipulated variable is, for example Fan speed the first input parameter, and the temporal change in the boiler temperature the second.
  • Characteristic data have been stored which indicate a first desired behavior of the Actuator with different performances, but fixed energy content of the fuel and determine fixed other influences. Characteristic data have also been saved, which one second behavior with different energy contents and this time determine fixed performance.
  • control device uses boiler temperature changes to determine which do not correspond to the course of the manipulated variable of the fan speed, any Changes in the current energy content of the fuel supplied and generated by means of Characteristic data for the second behavior and considering the ionization signal corrected performance-related control curve.
  • the control signal is in the case of a dynamic Power change the corrected control curve, for example, at a constant distance consequences.
  • Burners of various types are possible as burners, for example premix gas burners or atmospheric burners with and without auxiliary fans.
  • At atmospheric Burners without auxiliary fans can use the air volume flow z. B. via an air flap or the like. to be controlled.
  • the controller at least generates the control signal temporarily by processing the control signals and the controller determines the processing at least temporarily depending on the ionization signal.
  • control unit generates in one quasi-stable state no control signals.
  • the control device then makes a clean one Regulation via the ionization signal. But as soon as a quick change of state occurs, switches the control device to the quickly reacting and precise control by a Processing the control signals around. How the control signals are processed is for example, previously determined by the ionization signal and remains throughout Steering period equal.
  • the control system is only replaced by a control system when the State has calmed down and the ionization signal has lagged behind the current state.
  • the control signals are generated permanently and both carry them the control signals and the ionization signal continuously contribute to the control signal. Mixed variants are also possible.
  • controller at least temporarily Control signals weighted and added and that the controller at least temporarily the weighting determined depending on the ionization signal.
  • the controller dampens rapid fluctuations in the Ionization signal compared to slow fluctuations before processing the Control signals.
  • the controller has a low-pass filter for the ionization signal or equipped for a follow-up signal generated by processing, or with a Integrating unit for the ionization signal or for a subsequent signal generated by processing.
  • control unit also contains characteristic data Determination of a behavior of the ionization signal stored, generates the control unit at least temporarily a setpoint signal and the controller generates the control signal at least temporarily depending on the setpoint signal.
  • the controller is advantageous with a Comparison unit equipped, which at least temporarily the setpoint signal or by Processing generated sequence signal subtracted from the ionization signal.
  • the controller can generate the control signal so that the ionization signal is directed to the Setpoint signal is regulated. This difference can be achieved by means of the above-mentioned integration unit be regulated to zero.
  • Another embodiment of the invention relates to the stored characteristic data. That is advantageous first behavior of the actuator during burner operation with a first fuel been determined, and the second behavior of the actuator during burner operation a different second fuel in terms of energy content, especially if the specific energy content of one fuel is at least 5% higher than that of another Is fuel.
  • the characteristic data for determining the two behavior of the Actuator result from measurements. Alternatively, only the characteristic data for the first behavior of the actuator determined based on measurement results. The key data for that second behaviors are then calculated from these. This is only possible if a specialist an appropriate knowledge of the behavior of the actuator among the different ones Circumstances.
  • the characteristic data for the second Behavior instead of using burner-specific measurements based on professional knowledge determined on the fuel mixtures supplied in practice.
  • the invention also relates to a method for setting an inventive control device.
  • a burner with an inventive control device is first and equipped with additional sensors to determine the quality of the combustion. Then one operates the burner with a first fuel with a certain energy content different performance values each with different actuator positions, whereby one from determines the desired actuator status for each performance value from the sensor results. Out The desired actuator levels are used to determine the first behavior of the actuator. Then you run the burner with a second fuel a different energy content with different performance values different actuator levels, taking from the sensor results for each Performance value determines a desired actuator status, and now provides the desired Final control element characteristics to determine the second behavior of the final control element. Optionally, you repeat these steps for a third or even more fuels. Finally, the identified data are stored in one or more control devices saved. As described above, there are advantages to being specific Energy content of one fuel is at least 5% higher than that of another fuel.
  • FIG. 1 schematically shows the functional principle of an ionization evaluator 14 in a control device according to the invention.
  • the flame 1 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 1 is present, a larger current flows in the positive half-wave than in the negative half-wave due to the flame diode 1a through the block capacitor 3. 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 voltage component.
  • the low-pass filter filters out the DC voltage 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 from the high pass 6 is amplified with possibly small alternating current components and the reference voltage U Ref is added.
  • the AC voltage emerging from the amplifier 7 and the DC voltage emerging from the amplifier 8 compared with one another and a pulse width modulated (PWM) signal generated. If the amplitude of the mains voltage changes, see above AC voltage and DC voltage change in the same ratio, the PWM signal does not change.
  • the monoflop 11 is triggered such that the pulse sequence output from the comparator 10 comes faster than the pulse duration of the monoflop. This means that if there is no flame, a 1 constantly appears at the output of the monoflop. If there is a flame, the monoflop is not triggered and a 0 permanently appears at the output.
  • the retriggerable monoflop 11 thus forms a " missing pulse detector", which converts the dynamic on / off signal into a static on / off signal.
  • FIG. 2 shows a block diagram of a control device 15 according to the invention.
  • the ionization electrode 16 projects into the flame 1.

  • the speed corresponds to a power requirement 22.
  • the speed signal 20 is about a filter 21 led to the control unit 23, which as a program part to run in one Microprocessor has been designed.
  • Characteristic data are stored there, which are the characteristic curves define a first and a second control signal 24 and 25.
  • the controller 26 weights and adds the two control signals and thus determines the control signal 18. This processing of the Control signals depend on the ionization signal 13.
  • the ionization signal 13 is first smoothed by the controller 26 by means of a low-pass filter 27 in order to To suppress glitches and flickering.
  • a comparison unit 28 one of the Control unit 23 generates setpoint signal 30, which is guided via a correction unit 29 subtracted.
  • the sequence signal of this processing of the ionization signal is converted by a Proportional controller 31 and a parallel integrating unit 32 determines an internal control value x, which weights the two control signals 24 and 25 and thus finely regulates the control signal 18.
  • the control value x can alternatively be a PID controller or a status controller the following signal are generated.
  • FIG. 3 shows how the control signal 18 depends on a control device 15 according to the invention runs from the speed signal 20.
  • the characteristic curves of the control signals 24 and 25 each relate to one Fuel gas with a fairly low or rather high calorific value.
