Which dust collection device is considered the most effective and appropriate for extracting fly ash from flue gases in a thermal power station?

Explanation

Among various dust removal methods, the electrostatic precipitator is the most efficient and widely used equipment for capturing fine fly ash particles from flue gases in thermal power plants. Gravity settling chambers and cyclone separators are less effective for fine particles, while bag filters, though effective, are not as commonly used for large-scale fly ash removal.
