摘要

We present a novel non intrusive optical system for the on-line characterization of coal fired power plants flue gases. The system carries out both real time particle sizing of solid particles (in the range 0.1 - 10 μm) and concentration measurements of chemical species (as small as few ppm) downstream the electrostatic precipitators. The principle of operation relies on a multi-wavelength extinction technique based on the measurement of the extinction coefficient as a function of the illuminating wavelength.
