Abstract
The purpose of this project was to assess the feasibility of in-stack monitoring of an air-suspended particulate stream by fluorescence or Raman optical interactions. The study explored the feasibility of two approaches: quantitatively monitoring a prescribed constituent, and monitoring the relative concentrations of several constituents simultaneously. The method of approach was to assess the magintude of the Raman and fluorescence interaction, and then calculate the detectability of that material for a typical in-stack system. A few crude experiments were made to detect the fluorescent response of a particulate material suspended in a liquid. It is concluded that both fluorescence and Raman in-stack monitoring systems can yield useful information about the quantity and composition of a particulate stream. Recommendations are made for additional efforts toward achieving an operational in-stack monitoring system. (Modified author abstract)
