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 ionization signal is adjusted over the entire operating range of the burner the gas / air mixture used to different Gasquälticianen.
  • the ionization signal At low Operating loads of the burner, the ionization signal, however, strong external influences dependent and therefore provides no reliable information about the actually in the burner prevailing combustion conditions.
  • the regulatory procedure according to the state of Technology therefore lead to an unstable and therefore insufficient regulation.
  • EP 0 962 703 A2 is a control method disclosed for gas burners. In this regulatory procedure will in an area near the burner full load operation Ionisation signal of a sensor for setting a Translation ratio used. Outside the range of burner full load operation, the gas / air mixture in Dependent on this translation ratio.
  • the present invention is based on the problem, a to provide improved control method for gas burners. According to the invention Problem solved by a control method with the features of claim 1.
  • 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 stage pressure is called the gear ratio.
  • the ionization signal is used exclusively for setting the Gear ratio used depending on the gas quality, if the Burner flame completely covers the ionization signal generating sensor.
  • This inventive feature is based on the idea that only during this Operating state or operating state of the burner, the ionization signal a reliable Statement about the combustion process supplies.
  • the condition as to whether the burner flame is the sensor generating the ionization signal completely swept or not, may e.g. with an additional optical Flame monitoring device to be checked.

  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 des qualités de gaz différentes,
       caractérisé en ce que le signal d'ionisation est utilisé pour régler un rapport de transformation exclusivement quand la flamme du brûleur balaie complètement le capteur qui génère le signal d'ionisation,
       et en dehors de cette plage, c'est-à-dire quand la flamme du brûleur ne balaie pas complètement le capteur qui génère le signal d'ionisation, le mélange gaz/air est réglé en fonction du rapport de transformation défini au préalable.
