For a gas from the B / P gas group, the regulated characteristic point lies above the limit characteristic curve 19.

The time limit of the detection of a wrong set characteristic is advantageous, because it prevents false detection because of extreme environmental influences. Such extreme environmental influences are, for example, a cover of the exhaust path during the life of the burner device.
  • the limit characteristic curve 19 can move into the bands 17 and / or 18. This case is in FIG. 5 shown.

Above the boundary characteristic 21 one surely has E gas as fuel gas 6. Below the limit characteristic 21 one has Fuel gas 6 either E-gas or B / P gas.

If the position of the fuel valve 5 is adjusted so that it is above the limit characteristic curve 21, then the setpoint value of the ionization current over the entire power range is preset via the predetermined nominal value characteristic curve 15. This is possible because it is ensured above the limit characteristic curve 21 that only E gas is present as fuel gas 6 in the supply line. If the limit characteristic curve 21 is undershot, B / P gas could also be present as fuel gas 6 in the supply line. In this case, a setpoint characteristic 23 is specified, which adjusts the device to a larger A value.
