SOremoval equipment for reducing sulfur oxides from flue gas from a boiler, a cooler which is provided on a downstream side of the SOremoval equipment for reducing the sulfur oxides that remain in the flue gas and for decreasing a gas temperature, COrecovery equipment which includes a COabsorber, and an absorption liquid regenerator, and mist generation material reduction equipment for reducing a mist generation material which is a generation source of mist that is generated in the COabsorber of the COrecovery equipment before introducing the flue gas to the COrecovery equipment are included.

Air pollution control system and method

SOremoval equipmentwhich reduces sulfur oxides from flue gasfrom a boiler, a coolerwhich is provided on the downstream side of the SOremoval equipmentso as to reduce the sulfur oxides from the flue gas and decrease a gas temperature, COrecovery equipmentwhich includes an absorber for bringing COin the flue gas into contact with a COabsorption liquid so as to be reduced and a regenerator for causing the COabsorption liquid to emit COso as to recover COand regenerate the COabsorption liquid, and ammonia injection equipmentfor reducing a mist generation material which is a generation source of mist that is generated in the absorber of the COrecovery equipment before introducing the flue gas to the COrecovery equipment, are included.
