Abstract
A method of regulating a burner which is supplied with an air-fuel mixture includes: determining a regulating variable based on an ionization signal, the air-fuel mixture being set depending on the regulating variable and a setpoint value; obtaining a spectrum from the ionization signal, from which a measure for a surface area is determined; and adjusting the setpoint value depending on the measure for the surface area. Also described is a burner arrangement including a burner.
Claims10
A burner arrangement, comprising:
- a burner;
- a heat exchanger;
- an ionization electrode configured to measure an ionization signal;
- an air-fuel-mixture supply configured to supply an air-fuel mixture to the burner;
- and
- a control device configured to:
- determine a regulating variable based on the ionization signal;
- act on the air-fuel-mixture supply to set the air-fuel mixture for the burner depending on the regulating variable and at least one setpoint value;
- obtain, by a Fourier transformation, a spectrum from the ionization signal;
- determine a value of an area under the spectrum or under at least one frequency range of the spectrum;
- and
- adjust the at least one setpoint value depending on the value of the area.
