Dry electrostatic precipitator: This precipitator is used to collect pollutants like ash or cement in a dry state It consists of electrodes through which the ionized particles are made to flow through and a hopper through which the collected particles are extracted out...
There are, however, adjustments in the details that make the electrostatic precipitator work more effectively in different situations For example, there are precipitators that are scaled up to be more effective for low-sulfur coal, which produces more ash and therefore needs more energy to trap the high amounts of smoke...
It is important to note that the drift velocities shown below are highly dependent upon not only the upstream process but the configuration and design of the precipitator as well For example two identical processes each with their own precipitator made by a different manufacturer will often have different apparent drift velociti...
