Abstract
In a temperature measurement method for determining the adiabatic temperature of a flame, in particular in the combustion chamber of a gas turbine, the chemiluminescence radiation from the flame, emitted by OH radicals and CH radicals, is detected using a spectrograph via an optical sensor fiber. The spectrally resolved raw signal of the chemiluminescence radiation is then corrected and compared with a multiplicity of theoretically determined emission spectra, until a theoretical emission spectrum coincides with the chemiluminescence spectrum. The Boltzmann temperature associated with this coinciding emission spectrum is then assigned to the chemiluminescence spectrum, the adiabatic flame temperature being derived from the Boltzmann temperature by correlation.
