SERIES 100 FT-IR EMISSION/TRANSMISSION SPECTROMETER

The Series 100 is currently not being built for sale. Advanced Fuel Research, Inc. does offer an emissometry testing service - please see information on the Series 205 Spectral Emissometer.

 The Series 100 performs on-line and in-situ monitoring of combustion devices including:

bulletgas composition and concentrations
bulletgas temperature
bulletsoot concentration and temperature
bulletparticle size, composition and temperature
bulletemission and transmission tomography

The system performs simultaneous Fourier Transform Infrared (FT-IR) emission and transmission spectroscopy. Tomographic reconstruction of spectra from multiple lines-of-sight can be used to obtain spatially resolved spectra. The spectra are analyzed using automated routines which match observed spectra with library spectra. Measurements of gas concentrations are based on the absorption of radiation transmitted through the sample. Temperatures are obtained from a combination of emission and absorption. Particle size is obtained by examination of the wavelength dependent scattering of radiation by diffraction. These measurements are described in several publications. , , Several of these measurement methods have been successfully employed in commercial industrial plants under harsh conditions. Recent improvements include the use of Hadamard signal encodement of the tomographic data to increase the signal-to-noise (S/N) ratio and simplify the tomographic apparatus.
