The use of electrostatic precipitator on glass furnaces
is a novel, technological breakthrough; in fact, theChicago Heights precipitator is the only one of its kindin operation in the United States; and2.
The efficiency of the precipitator with higher volumes
of air can be calculated, but actual emission testingwould provide the best basis for determining the actualemission rates.
The present variance requ...
