Noun

sneakage ‎(uncountable)

1. The situation where gases carrying dust bypass the active electrode system of an electrostatic precipitator.
   • 1996, Howard D. Hesketh, Air Pollution Control: Traditional Hazardous Pollutants, ISBN 1566764130:

     Improved performance is obtained by reducing gas flow unevenness, dust flow unevenness, dust reentrainment, and gas sneakage.

   • 2012, Barbara Toole-O'Neil, Dry Scrubbing Technologies for Flue Gas Desulfurization, ISBN 1461549515, page 57:

     Sneakage and poor gas flow distribution adversely affect the collection efficiency. Sneakage occurs when a portion of the gas bypasses the electrified regions of the ESP by flowing through the hopper area and high voltage feed-through areas.

   • 2012, K.R. Parker, Applied Electrostatic Precipitation, ISBN 9400915535, page 137:

     Gases flowing between the very outmost collector plates and the wall of the housing, and gases flowing above and below the electrode systems, carry dust and give rise to sneakage.
