Definitions

  • the invention relates to a control method for gas burners.
  • Control methods for gas burners serve the provision a gas / air mixture, ie the supply of a gas stream and a combustion air flow to a burner.
  • the gas burner has a properly tuned Gas / air mixture are supplied.
  • the relationship between the gas stream and the combustion air stream or the gas pressure and the combustion air pressure are called as a gear ratio.
  • the quality of the Gas supply of provided gas - quality of gas is defined by a so-called Wobbe index, varies, needs to ensure optimal and complete Combustion of the gas / air mixture depending be varied according to the quality of the gas.
  • From DE 196 18 573 C1 is a method and a device for the operation of a gas burner, in which a Continuous monitoring of the burner performed becomes. For safety reasons is a shutdown of the burner provided that shuts them off as soon as irregularities be detected during operation of the burner. Furthermore, from this document known, the burner or the control circuit of the burner at regular intervals to calibrate to function properly to ensure the device.
  • DE 196 39 487 A1 describes a method and a device for optimizing the operation of a gas burner. According to This document is intended to carry out calibration procedures to ensure the proper operation of the burner. The document shows that at Installation of the burner once or twice a day this or the control should be calibrated. Furthermore, can in case of rarely activated systems, every activation is on be preceded by such calibration. The attachment So should be calibrated regularly when installing the burner and continue to calibrate before each turn on be carried out to ensure proper operation to ensure the burner.
  • EP 0 209 771 A is a control method for gas burners known in which uses a signal of a sensor is the gas / air mixture to different gas qualities adapt. This signal is exclusive to selected times, e.g. during commissioning for adaptation of the gas / air mixture supplied to the burner is used to different gas qualities.
  • the invention is based on the object, a control method to create a gas burner that is optimal Operation of the gas burner even over a longer period guaranteed.
  • the regulation procedure for gas burners is about the Provision of a gas / air mixture for a burner.
  • the burner is a gas stream and a combustion air stream fed.
  • the ratio between gas flow and Combustion air flow or the ratio between gas pressure and combustion air pressure is referred to as a gear ratio.
  • a signal generated by a sensor is the Combustion process monitored in the burner.
  • the sensor it can be e.g. one ionization sensor, another Flame monitoring sensor, a gas quality sensor, a Noise gas sensor, a combustion gas sensor or the like act. From the sensor signal information about the Combustion process and thus the existing gas quality be won.
  • the signal of the sensor is exclusive at selected times to adjust the gas / air mixture used on different gas qualities. This ensures that the regulation through aging processes of the sensor is not adversely affected.
  • the signal of the sensor is in the immediate Following the installation of the sensor in the immediate Connection to a restart of the gas burner and / or immediately after a reset for adjustment of the gas / air mixture to different gas qualities is used, depending on the determined Translation ratio an area with a Upper limit and a lower limit for the transmission ratio of the gas / air mixture, and then, if the determined using the sensor signal transmission ratio leaves this area, the upper limit or the lower limit as the ratio of the Gas / air mixture used.
  • the upper limit or the lower limit becomes the lower limit as a gear ratio used. This can also be done negative influences on the regulation due to aging processes minimize the sensor.
  • control method according to the invention is independent of the type of sensor or system used. It can at conventional systems as described in DE 196 39 487 or so-called electronic gas regulators according to the WO 99/63272 and WO 99/63273 are used.
  • the inventive method also in modulating Gas regulators can be used, where in the immediate Following the installation of the sensor, in the immediate Connection to a restart of the gas burner and / or immediately after a reset only the gas / air mixture to different gas qualities is adjusted, but also the input signal for the modulating Gas regulator is optimized at these times.
  • the gas burner is then always with an optimized Gas / air mixture and an optimized input signal started for the modulating gas regulator. This has the advantage of having a calibration between the input signal and the output of such a modulating one Gas regulator can be omitted.
