Paper Abstract

Operation of combustion process in power boilers in such a way that pollution standards are met and corrosion is limited requires continuous measurement of concentration of selected gases in the near wall layer of power boilers. The absorption spectroscopy is one of methods that allow such measurement. Specificity of the medium in which the measurement is to be made (among other things: high temperature, difficulties in installation of sources and detectors) requires utilization of optical fiber technology. Absorption spectra overlapping in the medium infrared range is an additional hindrance which makes application of special measurement algorithms necessary. A concept of structure of optoelectronic analyzer of CO concentration in the near wall layer of power boilers has been presented. The analyzer is based on modified correlation absorption spectroscopy within the range between 1557 nm and 1600 nm. Simulation results have been presented as well.
