Definitions

  • the invention relates to a method for operating a heater, a computer program, a control and control device and a heater.
  • Gas-operated heaters often have a control of the combustion air ratio, also referred to as the air ratio lambda ( ⁇ ), based on a signal from a sensor that is arranged in a burner or in the vicinity of a flame or the burner of the heater and a conclusion about the Air ratio ( ⁇ ) allows.
  • ⁇ the air ratio lambda
  • the DE 10 2020 126 992 A1 proposes a method for operating a burner with a fuel gas containing more than 95% by volume of hydrogen, in which a temperature signal from the flame is included.
  • the temperature signal can be set up to check at least one mass flow sensor of the combustion air or fuel gas to be supplied. If a mass flow sensor fails, the burner can continue to operate by increasing the air supply for 1 to 10 seconds and, if the flame temperature increases, concluding that the ratio of combustion air to fuel gas is too low.
  • the disadvantage of this method requires the use of at least two mass flow sensors in order to achieve precise control of the combustion. Operating the burner by means of the proposed temporary increase in air supply and recording the temperature signal can only enable very imprecise combustion control.
  • a method for checking a gas mixture sensor in which a signal from an ionization sensor of the flame is detected and assigned to a signal from the gas mixture sensor.
  • the gas mixture to be burned can be changed and the resulting changes in the signals from the gas mixture sensor and ionization sensor can be recorded and evaluated.
  • This process is also complex and requires the use of a gas mixture sensor. In addition, the process is not suitable for use with a hydrogen-containing fuel gas.
  • a predetermined air mass flow can be set and a corresponding gas mass flow can be determined for the temperature T Max .
  • a determined sensor value can depend on both the air ratio and the mass flow of the combustion mixture of fuel gas and combustion air supplied to the burner. Therefore, the mass flow or volume flow of the combustion mixture is usually determined by a corresponding sensor and included in the control system.
  • the output of a conveyor device is usually used, for example a speed of a conveyor device designed as a fan.
  • the performance of the conveying device can often only allow a very inaccurate conclusion to be drawn about the mass flow of the combustion mixture; for example, an obstruction to the flow path of the combustion mixture or exhaust gas flow can lead to significant deviations. One reason for this could be an at least partially blocked exhaust system. A resulting inaccurate control of the air ratio can lead to unclean and inefficient combustion.
  • a simple and cost-effective method for operating a heater with control of the combustion air ratio, including a temperature signal from the flame is to be specified, which enables long-term precise control.
  • the method should be suitable for being carried out at least partially automatically. It should also be possible to ensure that the process can be used reliably for different fuels.
  • Steps a), b) and c) can be carried out at least once in the specified order during a regular operational procedure.
  • the implementation of steps a) to c) can be repeated several times, in particular permanently.
  • the method serves in particular for the long-term safe operation of a heater with a sensor-based control of the combustion air mixture, in particular a heater in which direct detection of a mass or volume flow of fuel gas and combustion air to be fed to a burner of the heater is not possible.
  • the heater can include at least one heat generator, in particular a gas condensing boiler, which releases heat energy by burning a fuel and can transfer it to a heating circuit via at least one heat exchanger, whereby consumers of the heating circuit can be connected to the heater via a heating flow and a heating return.
  • the exhaust gases produced during combustion can be fed to an exhaust system via an exhaust duct of the heater.
  • a circulation pump can be set up in the heating circuit to circulate a heat transfer medium (heating water), with heat transfer medium heated via a heating flow being supplied to consumers, such as convectors or surface heaters, and being returned to the heat generator or the at least one heat exchanger via a heating return.
  • the heater can have a conveying device, in particular a fan, which supplies a combustion mixture of combustion air and fuel gas, for example fossil gas or hydrogen, to a burner of the heater.
  • the heater can have a sensory control of the air ratio ( ⁇ ).
  • the heater can have at least two flame sensors, which allow conclusions to be drawn about the combustion air ratio.
  • the at least two flame sensors can have different characteristics in relation to the (currently measured) power of the heater and/or the air ratio. In particular, based on a first signal from a first flame sensor and a second signal from a second sensor based on which different characteristics in terms of power and / or air ratio are determined accordingly.
  • the term "different characteristics with regard to a power/and/or an air ratio” here refers to the fact that a first connection between the first sensor signal and the air ratio and/or the power is (clearly) different from a second connection between the second sensor signal and the air ratio and/or or the performance of the heater differ from each other in such a way that an intersection can be determined as clearly as possible.
  • the relationships themselves or their gradients can differ significantly from one another.
  • the different characteristics can be recognized, for example, by the fact that the same burner situation leads to (significantly) different measurement results or signals.
  • a different signal is generated by the two flame sensors at the same time or in the same period of time, and it is precisely from this different characteristic that statements about the actual air ratio and/or performance of the burner can be derived, in particular by comparing both signals and/or or a joint assessment.
  • the mass flow ( ⁇ ) of the combustion mixture can be a measure of the performance of the heater. It is also possible for a volume flow of the combustion mixture to be used as a measure of the performance of the heater, which can be converted into a mass flow knowing the density of the combustion mixture.
  • the first flame sensor or the second flame sensor can in particular be an ionization electrode, a temperature sensor, a lambda probe or an optical sensor, in particular a UV sensor.
  • An ionization electrode is a device for measuring an ionization current of a flame on the burner of the heater. By applying a voltage to an ionization electrode, an ionization current flowing, for example via a burner body, can be measured, which enables conclusions to be drawn about performance and/or air ratio.
  • the ionization electrode can advantageously be a hot surface igniter, which is also set up to serve as an ignition device for the burner. A hot surface igniter can thus enable the detection of a flame temperature and an ionization current of the flame, as well as serve as an ignition device.
  • first and second flame sensors are provided by a single sensor (flame sensor system), which is set up to receive a first and second signal, which have different characteristics in relation to the power and/or the air ratio ( ⁇ ) of the heater , can be realized.
  • a single sensor flame sensor system
  • An example of this can be a hot surface igniter described above.
  • the temperature sensor can in particular be arranged in such a way that a flame temperature of the heater can be detected.
  • the temperature sensor can be arranged in the combustion chamber of the heater, in particular in an area of the combustion chamber in which a flame forms during regular use.
  • the temperature sensor When the burner is in operation, the temperature sensor can be arranged in the area of the flame core, in the area of the flame base or the flame tip. Alternatively, an arrangement at a distance from the flame is also possible.
  • the flame temperature sensor could be attached or arranged on the burner itself or on a burner door; advantageously, such a design can be easily integrated into existing assembly processes.
  • the temperatures to be measured by the flame temperature sensor can, for example, be in a range between 100 °C (degrees Celsius) and 1,500 °C.
  • the temperature sensor can be any temperature sensor, which in particular can deliver or provide an electrical signal as a measure of its temperature.
  • the signal can, for example, consist of a measurable electrical resistance, for example a measuring resistor, such as a platinum or silicon measuring resistor, a thermistor (NTC) or a thermistor (PTC) as a flame temperature sensor.
  • the flame temperature sensor can also be a semiconductor temperature sensor, which can provide a directly processable electrical signal representative of the temperature.
  • temperature sensors comprising a quartz oscillator, a thermocouple, pyroelectric materials and/or a fiber-optic temperature sensor can also be provided as the flame temperature sensor.
  • the flame temperature sensor can also be a hot surface igniter, i.e.
  • the complexity of a heater to be proposed here can be reduced, since the ignition device and temperature sensor and a device for heating the temperature sensor can be implemented using just one component.
  • the temperature sensor can be a silicon nitride or a silicon carbide hot surface igniter.
  • a lambda sensor can be a known lambda sensor designed to determine an oxygen content in the exhaust gas flow of the heater. Based on this information, a conclusion can be drawn about the combustion air ratio of the combustion mixture. By including a second flame sensor, which enables a conclusion to be drawn about the mass flow of the combustion mixture, the mass flow and/or the air ratio can also be determined using a lambda sensor using a method proposed here.
  • An optical sensor can be set up to detect electromagnetic radiation emitted by a flame of the heater.
  • the radiation to be detected can (for humans) visible light, infrared radiation (IR) and/or ultraviolet radiation (UV).
  • signals from the first and second flame sensors can be detected in step a), the first and second flame sensors being different flame sensors.
  • Flame sensors can advantageously be selected which themselves or due to the sensor have significant or clear differences in the characteristics with regard to the performance and/or the air ratio of a heater.
  • signals from the first and second flame sensors can be detected in step a), the first and second flame sensors being arranged at different positions in relation to the burner of the heater or to a flame occurring on the burner.
  • the first and second flame sensors can in particular have a (significantly) different distance from the burner or the flame.
  • step b) the air ratio ( ⁇ ) and/or the mass flow (m) can be determined using multidimensional (mathematical) functions.
  • a first and a second flame sensor can also advantageously be provided, which themselves or due to the sensor have significant or special differences in the characteristics with regard to the performance and / or the air ratio of a heater.
  • a change in a signal from such a flame sensor can usually be due to a change in the air ratio and/or a change in the output of the heater, combined with a change in the mass or volume flow of the combustion mixture.
  • a signal change that indicates an increase in flame temperature can be due to an increase in power or a change in air ratio.
  • mass flows of the combustion mixture for various incoming sensor signals can be understood as a three-dimensional function and two three-dimensional functions can be formed which represent the (first or second) signal of the (first or second) flame sensor as a function of mass flow and air ratio.
  • a two-dimensional function can now be formed that represents the mass flow as a function of the air ratio or the air ratio as a function of the mass flow.
  • a sensor value for example a flame sensor voltage of 1.43 V
  • two two-dimensional functions can be determined, the intersection of which can indicate an operating point.
  • a three-dimensional function can be determined for the first and second signals, wherein a first function can represent the mass flow depending on the first and second signals and a second function can represent the air ratio depending on the first and second signals. This makes it possible to directly determine the mass flow and air ratio.
  • a three-dimensional function described above, representing all possible combinations of air ratio and mass flow of the combustion mixture (or power of the heater) for various incoming sensor signals, can be determined, for example, by means of a reference heater with a correspondingly arranged first and second flame sensor, whereby the air ratio and power of the reference heater are known and so a connection between the sensor signal (from the first and second flame sensor) and an air ratio and a performance of the heater can be determined, for example, based on map recordings of the heater.
  • further operating parameters of the heater can be included in carrying out step b). Including additional operating parameters of the heater can enable a more precise determination of the air ratio and performance of the heater.
  • the further operating parameters can be an ambient temperature, a temperature in the supply of combustion air, a power of a conveyor device of the heater and/or a temperature in a flow and/or a return of the heater.
