Title: Flue gas conditioning for improved particle collection in electrostatic precipitators. Third topical report, Results of performance testing of additives

Technical Report ·
OSTI ID:48681

The purpose of this research program is to identify, evaluate, and develop cost-effective electrostatic precipitators (ESP) conditioning agents to improve removal of fine particle air toxics from coal-fired combustion flue gas streams. This goal can be met by reduction of reentrainment losses of collected ash and by control of ash resistivity. The project has focused on the development of cohesive agents to overcome reentrainment problems associated with low particle holding force. This effort has encompassed an extensive laboratory screening, followed by bench-scale and pilot-scale tests at the Consol research coal combustion facility. Initial laboratory screening with a variety of agents indicated qualitative improvements in ash layer mechanical characteristics. Further tests at the pilot-scale were inconclusive, in part because it was found to be difficult to develop low resistivity reentrainment conditions in the pilot-scale ESP available to the project. Results of the bench-scale and pilot-scale tests at Consol`s coal combustor are presented in previous project reports.
