Abstract

In a flue gas desulfurization equipment according to a seawater method, any lowering of decarbonation performance at the operation of decarbonation of used diluted seawater is prevented or suppressed by promoting the mixing/dilution between used seawater and diluent seawater. In flue gas desulfurization equipment (1) structured so that used seawater after desulfurization falls in diluent seawater flowing through water channel (9) and that used diluted seawater having been diluted by the mixing with diluent seawater, during its flow through the water channel (9), is decarbonated, turbulence generator (20) capable of promoting the mixing of used seawater with diluent seawater is disposed in the water channel (9).
