Performance Testing of Electrostatic Precipitator Applicable for Clean Combustion Devices for Producer Gas Application

Electrostatic precipitators (ESPs) are well known particle separation devices used widely in several industries. It is found that applications of ESPs for gasification based power plants are not reported and there is no clarity on its performance in this environment. The gas output from the biomass gasifiers contains particulates, dust & tar (P&T) at a fairly low concentration levels of the order of a few PPM and still can be objectionable to applications and devices where the gas is used over a period of time. The current practice of having finer fabric filters work with a demand for higher O&M operations. In this context it is essential to bring the P&T to as lower level as possible so that the equipments using this in the downstream do not get affected.
