Abstract |
An electrostatically stimulated fabric filter (ESFF) demonstration lasting almost 4,000 hours took place at Alabama Power Company's Plant Miller. A 5,000 acfm pilot-scale pulse-jet fabric filter (PJFF), or baghouse, took a slip stream from Unit 2's 700 MW boiler. The baghouse was outfitted with a 5 by 5 array of filter bags. A high voltage corona electrode was located in the center of each four-bag bundle, so the PJFF could be operated as an ESFF if the electrodes were energized. A dedicated high voltage transformer-rectifier, controlled by an automatic voltage controller, provided secondary voltages and currents. The ESFF was typically operated at 35 kV and 3 mA, and the current density at the bag surface was 8.8 mA/ft(sup 2) (9.5 nA/cm(sup 2)). Three major tasks were completed under this cooperative agreement. The first was a long-term demonstration of electrostatically stimulated fabric filtration (ESFF). The second comprised preliminary performance testing of a two-stage ESFF using a cooledpipe particle charger and a separate array of collector electrodes. Preparation of a report summarizing the cost and performance of conventional and novel fine particulate matter (PM) control technologies, including ESFF was the third activity. |
