Definitions

  • the present disclosure deals with a power determination via a fuel parameter on a burner device.
  • it is about a direct determination of a power as a function of an air supply for a given air ratio ⁇ .
  • the air actuator characteristic and fuel actuator characteristic are determined via the power during the adjustment process. For example, the determination can be made from a low power to a maximum power or vice versa.
  • the air ratio ⁇ is set for each power point.
  • Air supply sensors can also be used to support this. Common air supply sensors are based on speed, mass flow, differential pressure, air volume flow, etc.
  • the absolute power is then determined by measuring the fuel supply at at least one point or at multiple points. With the help of the calorific value H u of the fuel currently fed in, the burner output is assigned to the respective characteristic curve points.
  • the power values of the other characteristic curve points are determined by interpolation, preferably by linear interpolation.
  • the air actuator characteristic and the fuel actuator characteristic are specified.
  • the characteristic curves were determined empirically in the laboratory.
  • the burner output is specified by a fixed function from one of the two characteristic curves.
  • Different characteristic curves and/or sets of characteristic curves, which are also fixed, are used for different fuels.
  • the air actuator characteristic may have to be corrected so that ⁇ remains unchanged.
  • the calorific value is the energy content per amount of fuel.
  • the change in a fuel composition is detected using a ⁇ sensor.
  • a ⁇ sensor For example, this can be an O 2 probe in the exhaust gas, from which ⁇ is calculated directly.
  • an ionization electrode whose signal is evaluated accordingly can also be used.
  • the air supply can be changed or the fuel supply can be corrected until the ⁇ sensor again measures the original value of an air ratio ⁇ . If the at least one air supply signal is adjusted in order to keep the air ratio ⁇ constant, the power at this characteristic curve point almost always changes with the fuel composition. If the fuel supply signal is adjusted in order to keep the air ratio ⁇ constant, the power changes depending on the fuel.
  • a new characteristic curve of the air actuator must be selected or calculated manually or automatically in the event of a performance correction.
  • Common gas types in burner devices are those from the E-Gas group (according to EN 437:2009-09) and gases from the B/P-Gas group (according to EN 437:2009-09). Like almost all gases from the second gas family (according to EN 437:2009-09), gases from the E-Gas group contain methane as the main component. Like all gases from the third gas family (according to EN 437:2009-09), gases from the B/P gas group are based on propane gas. The mixtures based on methane gas or propane gas ultimately represent mixtures from different gas sources with which the burner device can be supplied.
  • Characteristic curves are usually provided for different types of gas, which are selected on site during commissioning according to the existing gas group.
  • the setting is made, for example, by selecting one or more curves stored in the memory of a control unit.
  • Those characteristic curves reflect the course of the amount of fuel supplied to the burner in relation to the amount of air supplied. Instead of the amount of air supplied, the speed of a fan in the air supply of the burner can be plotted.
  • the position and/or the control signal of an air flap can also be used as a measure for the air supply.
  • the characteristic curves can, for example, be stored in tabular form with linear interpolation or also with the help of polynomials as a mathematical function.
  • This form of characteristic allocation is in the European patent EP3299718B1, issued on October 30, 2019 was granted, revealed.
  • a registration EP3299718A1 to the European patent EP3299718B1 was published on 21 September 2016 submitted.
  • the European patent EP3299718B1 takes no priority.
  • An amount of air is suitable as a performance value if the air temperature, air pressure or air humidity change only insignificantly or are recorded by measurement.
  • the influences of air temperature and air pressure are taken into account.
  • the influence of humidity plays a subordinate role, especially at lower temperatures.

  • Those specifications assume the same environmental conditions such as temperature and pressure ahead. Consequently, the actual value P act of the power of the burner device can be set directly via a power controller.
  • the actual air supply V ⁇ List is then adjusted to the target value V ⁇ Lsoll via a measured variable.
  • the fuel supply V ⁇ B follows the air supply V ⁇ L based on the set ⁇ value.
  • Another related objective of the present disclosure is to correct the air ratio ⁇ using the O 2 control loop with the determined correct fuel supply V ⁇ B as the actual value and the target value, which originates from a target value characteristic curve determined via an O 2 control. Rapid performance changes are made based on the stored characteristic curves.
  • the current output is always determined with the aid of the ⁇ value determined by measuring the O 2 value and/or the desired value of ⁇ , even with changing fuels.
