John Buschmann, Technology Manager at ALSTOM Power Inc., provided an overview of the proposed Utility MACT emission values and discussed the implications for utilities seeking compliance not only under Utility MACT but also under CSAPR and various other existing and anticipated regulations. The solution is not a one-size-fits-all approach but rather a careful balancing of combinations of AQCS technologies that make up an overall compliance plan.

Improving Electrostatic Precipitator Performance (Dry & Wet) - Hot Topic Hour August 25, 2011.
Four speakers with more than 100 years of precipitator experience addressed important issues. In order to address the reality of mass particulate monitoring and the concept of tons per year of emissions (as in Title 5 permits), utilities are going to have to obtain some facts on performance of equipment.

Improving Precipitator Performance by Randy Cook - Alstom Power - Hot Topic Hour August 25, 2011
Randy Cook, Manager of Business Development at Alstom Power, Inc, observed that contrary to popular belief, many of the existing ESPs can be rebuilt to meet the stringent emission requirements of pending regulations. A combination of multiple technologies for mechanical and controls upgrade will have to be used in most installations depending on fuel, existing ESP sizing and configuration. Changing electrode geometry, installation of high frequency power supplies, optimized rapping, advanced controllers with opacity optimization, power down rapping, and off flow rapping can achieve significant PM emission reduction without adding plate area or replacing the ESP by a fabric filter. If upgrade of the ESP alone cannot meet the emission requirement, it may be cost-effective to install a downstream polishing fabric filter.
