Definitions

  • the present disclosure relates to control curves, as used in connection with ionization in burner systems, for example in gas burners.
  • the present disclosure relates to the correction of such control curves taking into account the aging and / or drift of a sensor signal.
  • the air ratio during combustion can be determined by means of an ionization current through an ionization electrode.
  • An alternating voltage is first applied to the ionization electrode. Due to the rectifier effect of a flame, an ionization current flows as a direct current in only one direction.
  • the ionization current detected at the ionization electrode is plotted against the speed of the fan of a gas burner.
  • the ionization current is typically measured in microamps.
  • the speed of the fan of a gas burner is typically measured in revolutions per minute.
  • the speed of the fan of a gas burner is also a measure of the air volume flow and the performance of the burner system, that is, for a quantity of heat per time.
  • test points are plotted. First of all, these test points can be included in tests under laboratory conditions. The recorded values are stored and taken into account in an (electronic) control.
  • Ionization electrodes are subject to aging during operation. This aging is caused by deposits and / or deposits during the operation of a burner system. In particular, an oxide layer can form on the surface of an ionization electrode whose thickness changes over the course of the operating hours. As a result of the aging of an ionization electrode, a drift of the ionization current occurs. Consequently, a control curve recorded under laboratory conditions requires a correction from time to time, at the latest after 1000 to 3000 operating hours.
  • a control device with correction of the control curve of an ionization electrode is disclosed in EP2466204B1 ,
  • the correction of the control curve takes place in three steps.
  • the controller performs a regular operation.
  • the control device controls or regulates the actuators of the burner system to a changed feed ratio. In particular, the speed of the fan of a burner system is changed.
  • the control device adjusts an air volume flow of the burner system.
  • the changed feed ratio is above the stoichiometric value of the air ratio of 1.
  • the air ratio is reduced by 0.1 or by 0.06 to values greater than or equal to 1.05. From the detected ionization signal and from stored data, a setpoint value is recalculated in a third step.
  • the correction of the control curve presupposes that the heat generated during the duration of the test can also be dissipated to consumers such as heating or service water. Otherwise, the amount of heat generated during the test is higher than the amount of heat removed. As a result, the temperature in the system rises and the temperature controller of the system switches off the burner. The test on a certain air flow can not be completed in this case.
  • EP2466204B1 is registered on December 16, 2010 and issued on November 13, 2013. EP2466204B1 discloses and claims a control device for a burner system.
  • EP1293727A1 The European patent application EP1293727A1 is registered on September 13, 2001. EP1293727A1 teaches a control device for a burner according to the preamble of claim 1.
  • US5049063A was notified on 26 December 1989 and granted on 17 September 1991.
  • US5049063A discloses an apparatus for controlling the combustion of a burner.
  • the present disclosure is an improved correction of the control curve of an ionization electrode, which at least partially overcomes the aforementioned disadvantages.
  • the present disclosure is based on the finding that burner conditions and thus any corrections to a control curve change slowly during operation.
  • the conditions and, consequently, the due corrections along the control curves generally do not change abruptly. This allows an estimate of how a correction at a test point affects adjacent values.
  • the above finding allows the correction of a control curve during operation of a burner system and at any air flow rates.
  • the cited finding also makes it possible to correct a control curve in a calibration mode or maintenance mode of a burner system.
  • a first step several test points, ie ionization currents relative to blower speeds or air flow rates of the burner system, recorded. This ensures that at least one test point is close to the currently required air volume flow. If a test run is not possible at an existing test point, the correction determined for an adjacent test point is first calculated into the correction of the present test point. Thus, the thus-corrected present test point is equalized to adjacent test points.

  • An ionization electrode (2) detects an ionization current.
  • At the ionization electrode (2) is typically an AC voltage in the range 110 V ... 240 V at.
  • the ionization current detected by the ionization electrode (2) means that a DC voltage applied to the ionization electrode (2) is superposed by a DC voltage. This results in a direct current.
  • This DC increases with increasing ionization of the gas in the flame area.
  • the direct current decreases with increasing excess air of combustion.
  • a low-pass filter For further processing of the signal of the ionization electrode, it is common to use a low-pass filter, so that the ionization current is produced from the filtered ionization signal (4).

  • the flame amplifier (3) also closes the electrical circuit by connecting the flame amplifier (3) to the ground electrode of the burner.
  • the ionization signal (4) processed by the flame amplifier (3) is relayed to an adjusting device (5).

  • the request signal (11) can be imaged directly on the first control signal (8) of the blower (6). Furthermore, the mapping of the request signal (11) to a fuel valve as a first, power-carrying actuator is possible.
  • a second actuator (7) leads via the supply of fuel (13) to the air ratio.
  • the adjusting device (5) forms the predetermined request signal (11), ie the rotational speed feedback signal (9), to a nominal value of the ionization signal (4).
  • the fuel valve (7) regulated. In this way, a change in the ionization signal (4) via a second control signal (10) causes a change in the position of the fuel valve (7). This changes the flow of fuel (13).
  • the control loop is closed by causing a change in the amount of fuel for a given amount of air, a change of the ionization current through the flame (1) and through the ionization electrode (2). Associated with this is a change in the ionization signal (4) until its actual value again equals the predetermined desired value.
