Definitions

  • the invention relates to a control method for gas burners according to the preamble of Claim 1.
  • Control methods for gas burners serve to provide a gas / air mixture, that is, supplying a gas flow and a combustion air flow to a burner.
  • the ratio between the gas flow and the combustion air flow and the gas pressure and the combustion air pressure is called the gear ratio.
  • the quality of the gas supplied by the gas supply - the quality of Gas is defined by a so-called Wobbe index - fluctuates, must to Ensuring optimum and complete combustion of the gas / air mixture in Depending on the quality of the gas can be varied accordingly.
  • the present invention is based on the problem, a to provide improved control method for gas burners. According to the invention the problem by a control method with the features of claim 1 solved.
  • the control method for gas burners involves the provision of a gas / air mixture for a burner.
  • the burner is a gas stream and a Supplied combustion air flow.
  • the ratio between gas flow and Combustion air flow or the ratio between gas pressure and Combustion air pressure is called the gear ratio.
  • the ionization signal is exclusively in an area in the vicinity of a burner full load operation for setting the transmission ratio in Dependence of gas quality used.
  • This range is preferably between 70% and 100% of the burner full load, but can also be between 60% and 100% of the Brennerstollast Stahls lie.
  • This feature of the invention is the idea on the basis that only during this working state or operating state of the burner Ionization signal provides a reliable statement about the combustion process.
  • the gas / air mixture is dependent on the previously determined translation ratio.

Claims (2)

  1. Procédé de régulation pour brûleurs à gaz, pour fournir un mélange gaz/air, c'est-à-dire pour amener un courant de gaz et un courant d'air de combustion dans un brûleur, selon lequel on utilise un signal d'ionisation d'un capteur pour adapter le mélange gaz/air à différentes qualités de gaz, caractérisé en ce que
    a) le signal d'ionisation est utilisé pour régler un rapport de transformation uniquement dans une zone proche d'un fonctionnement à pleine charge du brûleur,
    b) en dehors de cette zone du fonctionnement à pleine charge du brûleur, le mélange gaz/air est régulé en fonction de ce rapport de transformation,
    c) la zone de la phase de procédé a) est située entre 60 % et 100 % du fonctionnement à pleine charge du brûleur.
  2. Procédé de régulation pour brûleurs à gaz selon la revendication 1, caractérisé en ce que le signal d'ionisation est utilisé dans une zone de 70 % à 100 % du fonctionnement à pleine charge du brûleur pour régler un rapport de transformation.
