Abstract (en)
[origin: EP0819889A1] The measuring device uses several optical measuring sensors (7) which are positioned directly adjacent the flame front (8) within a pre-mixing zone (3) for a burner (1). Each sensor is aligned parallel or coaxial with the fuel feed flow direction (5). Each sensor may have an associated optical fibre, and the fibres are combined to provide an optical fibre bundle for supplying the sensor signals to a spectrometer, for evaluation of the flame temperature via spectral analysis.
