Flue gas conditioning for fabric filter performance improvement

The objective of this project is to develop a particulate control technology that can reliably remove particulate matter with particle diameters from 0.01 to 10 micrometers from a flue gas stream, with a removal efficiency of at least 99.9% for all particle sizes, independent of coal type. The method involves injection of conditioning agents ammonia and sulfur trioxide into the flue gas upstream of a baghouse to increase particle collection efficiency and simultaneously reduce baghouse pressure drop. It is the goal of the proposed research to develop this technology to the point where it is ready for field testing at the pilot level or compartment level at a full-scale utility power plant. Accomplishments this quarter included the completion of tests with a powder characteristics tester to evaluate the effect of conditioning on physical ash characteristics.
