Definitions

  • the invention relates to a control device for a burner, which burner comprises a arranged in the flame region of the burner ionization electrode, and an actuator, which affects the fuel supply amount or the air supply amount in response to a control signal.
  • Ionization electrodes have long been used for flame monitoring in burners. In general, however, the ratio of the amount of air to the amount of fuel, often called lambda, matched with each power demand either by a controller or by a scheme with sensors on each other. In general, lambda should be slightly above the stoichiometric value 1 for each power demand, for example, 1.3.
  • Air-controlled burners react, unlike controlled burners, to external influences which change the combustion. They therefore have a higher efficiency and thus a higher efficiency and lower pollutant emissions and thus a lower environmental impact.
  • the sensors required for this often gas sensors, in particular oxygen sensors, or temperature sensors, are expensive, unreliable, in need of care and / or have a short service life for this purpose.
  • Rapid changes in fuel supply or air supply typically result from sudden changes in power demand.
  • changes in the air number and thus changes in the gas or air volume flow may be caused by changes in the fuel composition, changes in air pressure, gas pressure changes, temperature changes, soiling and wear of mechanical torch parts, etc.
  • the stored characteristic in the control devices IT 95U000566 and EP-A1-909922 sets at each air pressure of the blower, and thus at each requested power, a control signal, which corresponds to a nearly desired level of the actuator for the gas valve.
  • a control signal which corresponds to a nearly desired level of the actuator for the gas valve.
  • an alternative control device is described, according to which the air volume flow is adapted to the gas volume flow, and the characteristic curve approximately determines the desired fan speed as a function of the manipulated variable of the gas valve.
  • a burner-specific characteristic curve is obtained in that the burner is operated under varying load with changing actuator levels, with additional sensors measuring emission values and efficiency and thus determining the desired manipulated variables.
  • Air-controlled burners have advantages over devices that are controlled by means of characteristic curves. At constant power, changes in temperature, fuel pressure, air pressure, fuel composition, wear and soiling of mechanical parts, etc. drift away from the set operating point.
  • control devices cause IT 95U000566 and EP-A1-909922
  • a control based on the stored characteristic curve compensates for their imperfection by first shifting the last state of the control signal to a new value at a constant distance along the characteristic curve.
  • DE-A-19831648 It shows a method for the functional adaptation of a control electronics of a gas heater on the type-specific properties, which should proceed largely independently.
  • the control electronics With the control electronics, the combustion air volume flow and the fuel gas volume flow can be controlled in dependence on a combustion-dependent ionization signal.
  • the control electronics controls before the actual burner operation firing operations with different air flow rates and stores the resulting characteristics for future burner operation.
  • control device can be constructed in such a way that, on detection of suitable conditions, it itself carries out a setting procedure for the acquisition of new characteristic data.
  • occasional or periodic recalibration occurs to compensate for any creeping changes in the control system, such as wear or fouling of the ionization electrode.
  • control characteristics are automatically determined, even for gases that are not detected by the preset characteristics.
  • the characteristic data can be designed, for example, as the constants in a polynomial winding up to the third order.
  • the function approximately represented by the polynomial winding determines a relationship between an input parameter and the actuating signal.
  • the input parameter for the cams is initially the requested power, 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 or a measured variable that corresponds to the power
  • the control characteristics z.
  • Temperature signals of all kinds such as burner temperature, flow and return temperature, etc. Further examples include a pressure difference reading for determining the gas or air flow, a gas or air flow meter, or directly the drive signal for operating a gas valve or an oil pump.
  • the first and second behaviors of the actuator depend on input parameters that are the same size.
  • the measure of the requested power, or another physical quantity can be supplied to the control unit by means of a single input parameter, such as the manipulated variable of the fan speed, or by input parameters of different types, such as manipulated variable and measured variable of the fan beam.
  • control device has further measured values available during operation, from which it can determine, for example, the current energy content or the current pressure of the supplied fuel directly or indirectly, then the second input parameter can even represent another variable.
  • burners are equipped with a temperature sensor for the boiler temperature.
  • a change in the energy content of the fuel supplied has a change in boiler temperature.
  • the manipulated variable of the fan speed is the first input parameter, and the temporal change of the boiler temperature of the second.
  • characteristics have been stored, which determine a first desired behavior of the actuator with different benefits, but fixed energy content of the fuel and other fixed influences. Also, characteristics have been stored which determine a second behavior with different energy contents and this time fixed power.
  • the controller determines any changes in the actual energy content of the supplied fuel based on boiler temperature changes that do not correspond to the time history of the fan speed and generates a corrected power-dependent control curve using the characteristics for the second behavior and the ionization signal.
  • the control signal will follow the thus corrected control curve, for example at a constant distance.
  • Burners of various designs are possible, for example premixed gas burners or atmospheric burners with and without auxiliary blower.
  • the air flow z. B. via a damper o. ⁇ . are controlled.
  • the controller generates the control signal at least temporarily by processing the control signals and determines the processing at least temporarily as a function of the ionization signal.
  • control unit generates no control signals in a quasi-stable state.
  • the controller then makes a pure control of the ionization signal.
  • the controller switches to the fast-response and accurate control by processing the control signals.
  • the manner in which the control signals are processed has previously been fixed by the ionization signal and remains the same throughout the control period.
  • the control is only replaced by a control when the state has calmed down and the Ionisationssignal has lagged the current state.
  • the control signals are generated permanently, and both the control signals and the ionization signal continuously contribute to the control signal. Mixed variants are also possible.
  • the controller is at least temporarily weighted and added to the control signals and that the controller determines the weighting at least temporarily as a function of the ionization signal.
  • the controller attenuates rapid fluctuations of the ionization signal in comparison to slow fluctuations before the processing of the control signals.
  • the controller is provided with a low-pass filter for the ionization signal or for a processed signal generated by processing, or with an integration unit for the Ionisationss or for a generated by processing sequence signal.
  • the processing of the control signals is adjusted by these measures only with a certain delay and / or smoothing of the ionization, so that the anyway too slow ionization signal course after a sudden change in state does not interfere with the control signal. Only when the situation has calmed down will the ionization signal slowly act on the processing of the control signals to provide a fine tuning.
  • characteristic data for determining a behavior of the ionization signal are stored in the control unit, the control unit generates at least temporarily a setpoint signal and the controller generates the control signal at least temporarily in response to the setpoint signal.
  • the regulator device By means of these measures, the regulator device, or its regulator program, can be designed simply and achieve great reliability.
  • the controller itself occasionally or regularly calibrates these characteristics.
  • the controller is advantageously equipped with a comparison unit which at least at times subtracts the setpoint signal or a sequence signal generated by processing from the ionization signal.
  • the controller may generate the actuating signal in such a way that the ionization signal is regulated to the desired value signal.
  • the first behavior of the actuator during a burner operation has been determined with a first fuel
  • the second behavior of the actuator during a burner operation with a different in energy content second fuel, especially if the specific energy content of a fuel at least 5% higher than that of another Fuel is.
  • the characteristics for determining the two behavior of the actuator have resulted from measurements.
  • the characteristics for the first behavior of the actuator are determined based on measurement results.
  • the characteristics for the second behavior are then calculated from these. This is only possible if a person skilled in the art has suitable knowledge of the behavior of the actuator under the different circumstances.
  • the characteristic data for the second behavior are determined by means of burner-specific measurements based on expert knowledge of the fuel mixtures fed in practice.
  • the setting of a control device to a certain type of burner thus advantageously takes place in that two or more burner-specific characteristics during operation with different fuels, such as gas mixtures in different proportions, are determined.
  • the invention also relates to a method for adjusting an inventive control device.
  • a burner is first equipped with an inventive control device and with additional sensors for determining the quality of the combustion. Then one operates the burner with a first fuel with a certain energy content at different power levels, each with different actuator levels, wherein one determines a desired actuator state from the sensor results for each power value. From the desired actuator levels characteristics are determined to determine the first behavior of the actuator. Thereafter, the burner is operated with a second fuel having a different energy content at different power levels, each with different actuator levels, from the sensor results for each power value determining a desired actuator level, and now determining characteristics from the desired actuator levels to determine the second behavior of the actuator , Optionally, repeat these steps for a third or even more fuel. Finally, the identified characteristic data are stored in one or more control devices. As described above, it brings advantages that the specific energy content of one fuel is at least 5% higher than that of another fuel.

  • the flame 1 is represented by a diode 1a and a resistor 1b.
  • an AC voltage of, for example, 230V is applied.
  • a flame 1 is present, a larger current flows through the blocking capacitor 3 in the positive half wave than in the negative half wave because of the flame diode 1a.
  • a positive DC voltage U B is formed on the blocking capacitor 3 between L and a resistor 2 mounted for the purpose of contact protection.
  • a direct current flows from N to the blocking capacitor 3.

  • the high-pass 5 the alternating current is filtered out and the DC component blocked.
  • the low-pass filter is used to filter out the dc voltage component which is dependent on the flame resistance 1b and essentially blocks the alternating current.
  • the alternating current flowing from the high-pass filter 5 is amplified and a reference voltage U Ref is added.
  • the direct current flowing from the high-pass filter 6 is amplified with possibly small alternating current components and the reference voltage U Ref is added.
  • the alternating voltage emerging from the amplifier 7 and the DC voltage emerging from the amplifier 8 are compared with one another and a pulse width modulated (PWM) signal is generated. If the amplitude of the mains voltage changes, the AC voltage and the DC voltage change in the same ratio, the PWM signal does not change.
  • the monoflop 11 is triggered so that the pulse train output from the comparator 10 comes faster than the pulse duration of the monoflop. If a flame is present, the monoflop will not be triggered and the output will always show a 0.

  • the gas valve 17 is controlled by the control signal 18 in a direct or indirect manner, for example via a motor. Eventually, a mechanical pressure regulator is interposed.
  • An air blower 19 is driven to a speed which is used here as an input parameter.
  • the speed corresponds to a power demand 22.
  • the speed signal 20 is fed via a filter 21 to the control unit 23, which has been designed as a program part for execution in a microprocessor.
  • characteristic data are stored, which define the characteristics of a first and a second control signal 24 and 25.
  • the controller 26 weights and adds the two control signals and thus determines the actuating signal 18. This processing of the control signals depends on the ionization signal 13.
