    Absorption Spectroscopy a renown and established measurement technique

    Absorption spectroscopy measures the absorption of radiation (e.g. photons) at specific wavelengths. The absorption intensity varies as a function of frequency causing absorption spectrums.Absorption spectroscopy is employed as an analytical chemistry tool to determine the presence of a particular substance in a sample and to quantify the amount of the substance present. Infrared and ultraviolet-visible spectroscopy are common in analytical applications. Absorption spectroscopy is also employed in studies of molecular and atomic physics, astronomical spectroscopy and remote sensing.

    Combustion optimization strategiesMinimizing excess air increases efficiency + reduces NOx

    Measuring and homogenizing the combustion process avoids local emission & temperature peaks. This gives room for the optimization of the excess air level - beneficial for both the NOx emissions and the efficiency!

    Is the boiler operated in the comfort zone or in the optimum zone?
