the loss of an on-site electrostatic precipitator expert. This has created a void in which precipitator troubleshooting, operation and optimization may not be fully understood. Problems such as increased emissions, back corona and ineffective rapping (to name a few) may go undiagnosed which may lead to de-rates, upsets or shutdowns

For instance, electrostatic precipitator design requirements for fly-ash control from 1000-MW coal-fired power boilers differ from those for a chemical process operation. In the discussion that follows, priority is given to control technology for the CPI as opposed to the somewhat special needs of other industries

The collection of low resistive particles from diesel engine emission is difficult by the conventional electrostatic precipitators (ESPs). The low resistive diesel engine particles are detached from the collection plate, which causes the dust reentrainment, resulting in poor collection efficiency. The new electrohydrodynamically (EHD) assisted ESP (EHD ESP) was developed to minimize reentrainment
