In this study, the finite element strength analysis [23, 24] and lightweight optimization design of the main structure of the large electrostatic precipitator
were carried out using advanced design technologies such as finite element method, optimization design, and virtual prototype.

, Journal of Electrostatics 57(3-4): 407-415.
The study was focused on novel CFB OSA, the well-studied PF OSA from electrostatic precipitators
was used for comparison.

The results of numerical analysis confirmed that there is unsatisfactory uniformity of flow field inside considered actual electrostatic precipitator
and the certain flow corrections have to be made.
* Growing demand for electrostatic precipitator
The content of indissoluble residue (mainly quartz) increases along the ash separation system in both CFBC and PF ashes, being lower in bottom ashes and several times higher in electrostatic precipitator
CBC, a Brazilian subsidiary of Mitsubishi Heavy Industries, supplied the new equipment, which includes an electrostatic precipitator
for removal of particulate material.
Gaseous contaminants can be removed with an activated carbon filter, an oxidizing filter - carbon plus potassium permanganate - or an electrostatic precipitator
. Oxidizing filters chemically alter gaseous contaminants so that their odor or effects are eliminated; whereas activated carbon adsorbs and retains contaminants until the adsorptive capacity is reached.
"We found that [fly ash] is indeed a very strong catalyst,' says Karasek, "which causes dioxins to form from almost anything.' That process seems to occur most readily after the fly ash has cooled to about 300|C, often in a pollution control device such as an electrostatic precipitator
. The chief culprits are the heavy metals present in the fly ash particles.
We also prepared a preliminary economic analysis, which indicated that leaching and ion-exchange were the more attractive alternatives for treating ash collected from the electrostatic precipitator
