Particle Characterization Laboratory
Particulate characterization is one of our specialties. Our particle
characterization laboratory is located in Palatine, Illinois and
performs flyash resistivity and particle size distribution analysis.
A combination of laboratory data and computer modeling is used to
optimize the flyash collection efficiency of electrostatic precipitators
(ESP) and to predict the ESP performance over a wide range of flue
gas conditions, such as varying temperatures and SO3 concentrations.
The laboratory routinely performs the following:
- Coal-switching studies that evaluate the resistivity of select
coals and blends to predict ESP collection performance
- Studies of the effect of flue gas conditioning to improve ESP
collection
- Increasing
the generating output of units derated due to opacity
- ESP

Computer Model ESP Performance Predictions
Particle collection performance of an electrostatic precipitator
is predicted using customer-supplied precipitator mechanical and
electrical data as well as coal and fly ash compositional data. The model
is described in EPA-600/7-84-069 a&b and is commonly
referred to as the EPA/SRI computer model. In addition to modeling
the existing precipitator performance, the effects of various changes (such
as coal switching and gas conditioning) can be predicted. Priced according
to scope and complexity.
