Electrostatic Precipitation Lab

Since 1997, researchers and students in the Russ College’s Electrostatic Precipitation (ESP) Lab have specialized in discovering new and creative ESP designs that more efficiently remove particulates from coal-fired power plant emissions. Performing research from bench-scale up to pilot-scale, we examine almost every aspect controlling the electrostatic precipitator to reduce particulate emissions and develop new methods for particulate capture.

Facilities and Equipment

At 3,000 square feet, our ESP lab is one of only a few facilities in the world fully equipped with all the tools required to simulate, test, and analyze emission collection efficiency.

The laboratory has the capability to simulate full-scale conditions of typical emission capture situations with a pilot-scale ESP. This ESP has a testing space of 96” long by 83” tall–by 48” wide. The electric field is created by an NWL PowerPlus unit, rated at 70kV and 400mA. The gas flow is produced by a variable frequency drive fan, able to provide up to 10,000 cfm. Wide ranges of dust concentrations can be achieved, from 10mg/m3 ~ 100mg/mand up to 7.5g/m3 (concentrations based on 7,200 cubic feet per minute). Tests can also be carried out at elevated gas temperatures.

The laboratory has many methods of collecting and analyzing test data, including the Method 5 EPA standard for emission capture analysis, which is used in industry to determine the particulate levels being released into the atmosphere. By using isokinetic sampling, concentrations of particulate can be determined. This is a very trusted and reliable source of testing. Particulate concentrations are also determined using light scattering technology from the Thermo Scientific ADR 1500. The laboratory uses two units to provide real-time aerosol concentrations at the inlet and the outlet of the ESP.   

The laboratory will be installing SO2 storage systems as well as an SO2 to SO3 conversion and delivery system to the ESP testing facility. During that time, there will also be steam lines installed to increase the humidity up to 100% in the testing space.
