Optical investigations of the combustion characteristics of a gas turbine pilot burner
Author
Summary, in English
This paper presents the application of several optical measurement techniques for the characterization of the combustion behavior of the pilot burner of a gas turbine combustor developed according to the lean premixed prevaporized (LPP) concept. The vaporization of the kerosene fuel (Jet-A) and its consequent mixing with air has been visualized using combined Laser-Induced Fluorescence (LIF) and Mie scattering measurements. In addition the feasibility of using Laser-Induced Incandescence (LII) for soot characterization has also been investigated. Furthermore, spontaneous flame emission (i.e. chemiluminescence and thermal radiation) have been measured providing information on the overall characteristics of the combustion. The LIF/Mie measurements can also be used to estimate the length and time scales for evaporation and mixing with air of Kerosene (Jet-A) for the LP(P)4 pilot burner.
