# Tomographic temperature measurement on water vapor absorption in a pulverized solid fuel combuster under Oxy-fuel conditions

The swirled Oxy-fuel combustor studied here is described in [1,2]. For details on the measurement method please refer to the publication linked 
in an updated version of this dataset or contact the authors. 
The provided CSV-files contain measurement results in cylinder coordinates of the burner. The uncertainty values describe standard deviations 
calculated from a nonlinear uncertainty propagation of the spectroscopic regression.

Each file corresponds to ones operating point (RAIR, ROXY33, ROXY33P, RCAIR, RCOXY33, RCOXY33P).


IMPORTANT: Due to tomographic distortions the uncertainty in the inner region (r<25mm) is assumed to be 220 K, even if the uncertainty supplied 
by the uncertainty propagation (in the CSV-files) is lower.
