Abstract (en)

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.

Abstract (de)

Bei einer Temperaturmessvorrichtung, insbesondere für die Flammentemperaturmessung in einer Gasturbinenbrennkammer, sind eine Anzahl optischer Messensoren (7) unmittelbar stromaufwärts einer Flammenfront (8) in einer Vormischzone (3) eines Brenners (1) angeordnet. Jeder optische Messensor 7 ist im wesentlichen parallel und/oder koaxial zu einer in die Gasturbinenbrennkammer geführten Brennstoffströmung (5) ausgerichtet ist. <IMAGE>
