Two light-scattering particle size analyzers have been tested at ANL in the process development unit (PDU) fluidized-bed combustion system. The analyzers are (1) a single-particle analyzer developed by Spectron Development Laboratory and (2) a multiparticle analyzer developed by Leeds and Northrup. Particle size distributions and mass loadings determined at different flue gas duct locations with the two instruments have been compared with those obtained with (1) an Andersen cascade impactor, (2) a Coulter counter, and (3) positive filters. These comparisons were used to evaluate the two instruments at their present state of development. |
