Measurement of temperature and gas concentration in a flame using a FTIR imager

Nowadays, determining the temperature of flames is a challenging measurement in industry. The EMPIR project 14IND04 EMPRESS, in its WP4, address these temperature measurements. The Infrared Lab at the Physics Department of Universidad Carlos III of Madrid (UC3M) has developed a technique for measuring the temperature of a standard flame, in collaboration with the Centro Español de Metrología (CEM). An Imaging Fourier Transform Spectrometer (FTIR) has been used to acquire the emitted radiation coming from the flame and establish its temperature through several processing stages. This equipment has been calibrated with standard radiation thermometers and blackbodies at CEM
