摘要：
A process is disclosed for enhanced removal of SO.sub.2 and fly ash from flue gas by directing the flue gas and an SO.sub.2 sorbent through an electrostatic charger and then through a bag filter where electrostatically improved flue gas/sorbent contact occurs and where the suspended fly ash and sodium sulfate are removed and the gas stream is discharged.
