Abstract

Swirl injectors have been widely used in gas turbines to form the swirling flames, and thus increase the combustion efficiency. The temperature distribution of the swirling flame reflects the combustion efficiency to a large extent. In this paper, the tunable diode laser absorption spectroscopy (TDLAS)-based tomography system was developed to reconstruct the two-dimensional temperature distribution over the cross section of interest in the swirling flame. In lean-premixed combustion status, the system was demonstrated that it was capable of reconstructing the temperature distribution in situ and in real time. The measurement results were used to detect the processing vortex core located in the swirling flames and understand the flame stability in lean-premixed combustion.
