Definitions

  • the invention relates to a control method for gas burners according to the preamble of claim 1.
  • Control procedures for gas burners must undergo calibration at certain times, eg after installation of the control, restart or reset of the burner, see for example EP.962703 A .
  • the procedure so far is that a calibration is only carried out when the burner has been operated following the predetermined time for a predetermined period of time under stable operating conditions.
  • This so-called waiting time is required in order to ensure a reliable or stable calibration of the control. If the burner leaves the stable operating conditions during the calibration or during the specified period of time, the calibration is aborted according to the prior art and regulated according to the old setting or old calibration. This can be a considerable disadvantage, since the old calibration, for example due to a change in gas quality can no longer be true and then only a poor control can be performed.
  • the present invention is based on the problem to provide an improved control method for gas burners. According to the invention, the problem is solved by a control method having the features of patent claim 1.
  • the invention relates to a control method for gas burners for providing a gas / air mixture, namely for supplying a gas flow and a combustion air flow to a burner.
  • a calibration of the control is performed.
  • the calibration procedure is such that when, after the predetermined time, the burner has been operated for a predetermined period of time under stable operating conditions, the calibration is performed and the new stable calibration replaces the previous stable calibration.
  • the desired calibration point is immediately controlled, not the old stable calibration, as in the prior art.
  • a preliminary calibration is performed on the basis of the last operating conditions. This preliminary calibration then replaces the previous stable calibration.
  • the control can perform a stable calibration based on stable operating conditions, the provisional calibration is replaced by a new stable calibration.
  • the invention is therefore based on the idea that even a preliminary calibration for which the burners could not be operated for the entire predetermined period of time under stable operating conditions still represents a better setting for the control than the old stable calibration.

Claims (2)

  1. Procédé de régulation pour brûleur à gaz pour fournir un mélange gaz/air, à savoir pour acheminer un flux de gaz et un flux d'air comburant à un brûleur, un étalonnage de la régulation étant effectué à des instants prédéterminés et l'étalonnage étant alors effectué lorsque le brûleur, suite aux instants prédéterminés ou à chaque instant prédéterminé, a fonctionné pendant un intervalle de temps prédéterminé dans des conditions de fonctionnement stables,
    caractérisé en ce que
    a) lorsque le brûleur, suite aux instants prédéterminés ou à chaque instant prédéterminé, a fonctionné pendant un intervalle de temps prédéterminé dans des conditions de fonctionnement stables, l'étalonnage est effectué et le nouvel étalonnage stable remplace l'étalonnage stable précédent,
    b) lorsque le brûleur, suite aux instants prédéterminés ou à chaque instant prédéterminé, n'a pas fonctionné pendant un intervalle de temps prédéterminé dans des conditions de fonctionnement stables, un étalonnage provisoire est effectué sur la base des dernières conditions de fonctionnement présentes et la régulation s'effectue alors sur la base de l'étalonnage provisoire.
  2. Procédé de régulation selon la revendication 1,
    caractérisé en ce que
    lorsqu'un étalonnage provisoire a été effectué, l'opération d'étalonnage est répétée jusqu'à ce qu'un étalonnage ait lieu sur la base de conditions de fonctionnement stables conformément à la mesure a).
