Provided are: a wet desulfurization apparatus 13 which removes sulfur oxides in flue gas 12A from a boiler 11; a mist collection/agglomeration apparatus 14 which is provided on a downstream side of the desulfurization apparatus 13 and forms agglomerated SO 3 mist by causing particles of SO 3 mist contained in flue gas 12B from the wet desulfurization apparatus 13 to be bonded together and have bloated particle sizes; a CO 2 recovery apparatus 18 constituted by a CO 2 absorption tower 16 having a CO 2 absorption unit 16A which removes CO 2 contained in flue gas 12D by being brought into contact with a CO 2 absorbent and an absorbent regeneration tower 17 which recovers CO 2 by releasing CO 2 from the CO 2 absorbent having absorbed CO 2 and regenerates the CO 2 absorbent; and a mist collection unit 16C which collects CO 2 absorbent bloated mist bloated by the CO 2 absorbent being absorbed by the agglomerated SO 3 mist in the CO 2 absorption unit 16A.
摘要:
In a charging time period T1, a dry electrostatic precipitator outputs DCON that is a current for charging a collection target object from a high voltage power supply. Subsequently, in a second period of time T2-2 after a first period of time T2-1 passes from a time that a charging pause time period T2 starts, the dry electrostatic precipitator outputs DCBC that is a current that is less than DCON and is greater than a current in the first period of time T2-1, from the high voltage power supply.
