摘要：

Diagnostic tools for real time and direct gas analysis have been developed. The simultaneous measurements of gas and particle temperatures (280-330 degreesC) and gas concentrations (CO, CO2, HCl, H2O) are demonstrated in a hot particle-laden flue gas with a fibre-optic probe connected to a Fourier transform infrared spectrometer. The gas temperature is found from the thermal radiation at the 2350 cm(-1) CO2 fundamental band, whereas the gas concentrations are determined by comparing the measured transmittance spectra with a spectroscopic database and validation measurements using the Hotgas facility at Riso. Measurement uncertainties Lire discussed. The measured local gas temperatures and concentrations are in good agreement with measurements made with conventional equipment.
