Fly ash bin is one of electrostatic precipitator parts. Steam boiler use electrostatic precipitator for filter flue gas, so pollutant can be eliminated. Dust particles screening result from electrostatic precipitator (ESP) unit will be accommodated on the fly ash bin. The air from compressor pipe goes into fly ash bin will be thrown back into atmosphere with the help of fan. So the air inside fly ash remains vacuum. Installation of fly ash bin is equipped with double screw ash conveyor as shown in Figure 1 to throw dust particles into transport vehicle.
