abstract = "Non-intrusive and fast measurements of the gas temperature, NO and other gas concentrations at elevated temperatures in boilers, engines and flames are of the great interest. The optical properties of the gases must be known in a spectral range and temperature level of interest. High-resolution IR- and UV-absorption spectra of the NO have been measured with a hot gas cell operated from the ambient up to 1400 – 1500 °C. Similarly, high-resolution infrared absorption spectra of the H2O have been measured. Measurements are compared with simulated spectra using the HITRAN-2006 and HITEMP-1996 databases, and good agreement has been found for NO (e.g. deviations of 1-5% for NO at 1200 °C). Practical highresolution measurements at the AVV2 boiler are analysed, and detection limits for the NO are discussed. The developed tools and results will be used in the future projects, e.g. fast measurements of the gas composition in the near-burner field with co-firing of biomass and coal, and NO measurements in a large diesel engine.
