The World Speaks on Precipitator Power Supplies in Hot Topic Hour Yesterday

There were four speakers in the Precipitator Power Supplies Hot Topic Hour. We certainly proved that the webinar format allows instant worldwide communication. Only one of the four was speaking from the U.S., David Seitz of NWL.

Scandinavia accounted for 50 percent of the roster with Martin Kirsten of Alstom speaking from Sweden and Arne Haaland of Applied Plasma Physics speaking from Norway. Luke Wilkinson of Indigo Agglomerator must be a night owl because this is the second Hot Topic Hour in which he has recently participated from Australia, where it was 1:30 in the morning when he actually started speaking.

Three of the speakers discussed their versions of switch mode power suppliers (SMPS). NWL is selling them to 15 different ESP suppliers. Alstom on the other hand is manufacturing substantial quantities for use on their own precipitators. Applied Plasma Physics has manufactured over 200 SMPS for their own small precipitators and is gearing up to offer very large SMPS units using a modular concept.

The most experience to date has been gained on low resistivity dusts where efficiency improvements of up to 30 percent are typical. But the SMPS promises even greater efficiency gains on high resistivity coals.

Martin (Alstom) says that, in his opinion, it will be just a matter of time before SMPS completely supplants standard TR systems.

Indigo Agglomerator is enjoying success with pre-charging. There are a number of plants which have substantially reduced emissions and opacity by installing these pre-chargers. Questions relative to problems on one of them were asked of Luke. The Dynegy Havana station has been having build-up problems. It is a hot side precipitator with sticky dust. Sonic horns did not work; however, a United Technologies detonative cleaning device has solved the problem.
