fly ash handling system & ash handling techniques

for extraction of dry fly ash collected at Air Pre-Heater / Duct / Electrostatic Precipitator hoppers of PF type boilers. Vacuum System is generally adopted when the extraction distance is less, numbers of ESP hoppers are more and plant layout demands two-stage conveying. Vacuum System includes conveying of fly ash from various fly ash hoppers up to the intermediate / buffer / surge hopper (ISH) located near

basic electrostatic precipitator (esp) operation

A dry electrostatic precipitator (ESP) electrically charges the ash particles and imparts a strong electric field in the flue gas to collect and remove them. An ESP is comprised of a series of parallel, vertical metallic plates (collecting electrodes) forming lanes through which the flue gas passes
