In the context of Electrostatic Precipitators (ESPs), a “GD screen test” refers to a Gas Distribution (GD) test, which assesses the uniformity of gas flow across the ESP’s cross-section to ensure effective particulate collection. A uniform gas distribution is crucial for effective particulate collection in an ESP, ensuring that all areas of the ESP are utilized efficiently and that the dust particles are collected effectively.
Benefits
Create a uniform gas flow to the discharge and collecting electrodes.
Slow down gas velocity at the inlet area.
Control gas flow at the outlet area to prevent upstream of gas velocities.
