Abstract (en)

Controlling a mixing ratio. A method of controlling a mixing ratio of combustion air and a gaseous fuel comprising more than twenty percent of hydrogen gas, wherein the combustion air and the gaseous fuel are combusted together in a combustion chamber (2), the method comprising the steps: a first optical sensor (8) recording a first raw signal directly originating from a flame (1) inside the combustion chamber (2), producing a first sensor signal from the first raw signal, and sending the first sensor signal to a controller (14); the controller (14) determining a first signal strength of the first sensor signal; after recording the first raw signal, changing a supply of combustion air and/or of gaseous fuel to the combustion chamber (2); the at least one first optical sensor (8) recording a second raw signal directly originating from the flame (1) inside the combustion chamber (2).
