Abstract
This invention relates to a method of monitoring a burner (2) and/or a burning behavior of a burner (2) by means of a measured ionization signal. The invention consists in that the ionization signal is measured between an ionization electrode (4, 4′) and a counter-electrode (3) spaced apart from a burner surface (2′) of the burner (2). Furthermore, the invention relates to a burner assembly.
Claims4
A method of monitoring a burner and/or a burning behavior of a burner, the method comprising:
- measuring ionization signals,
- wherein the measured ionization signals are used for monitoring the burner and/or the burning behavior of the burner,
- wherein the ionization signals are respectively measured by the ionization electrode by using the burner surface and the heat exchanger as a common counter-electrode,
- wherein for a calibration and/or for a determination of parameters used when monitoring the burner, the ionization signals are measured during a hyperstoichiometric combustion, and
- that a local extremum of the ionization signals is determined during the hyperstoichiometric combustion in dependence on a lambda-value of an air-fuel mixture supplied to the burner and is used for the calibration and determination.
2 more elements
A burner assembly comprising:
- a burner, a heat exchanger, at least one ionization electrode, an air-fuel mixture supply unit for the burner, and a control device,
- wherein the control device is connected to the at least one ionization electrode,
- wherein, based on ionization signals measured by the at least one ionization electrode, the control device monitors the burner and/or a burning behavior of the burner,
- wherein for monitoring the burner and/or a burning behavior of the burner
- the control device uses ionization signals measured by the ionization electrode by using the burner surface and the heat exchanger as a common counter-electrode, respectively,
- wherein for a calibration and/or for a determination of parameters used when monitoring the burner, the control device leans the air-fuel mixture supplied to the burner via the air-fuel mixture supply unit, and evaluates ionization signals measured by the leaned air-fuel mixture, and
- that for the calibration or the determination of the parameters the control device determines a local extremum of the ionization signals by the leaned air-fuel mixture.
