| 摘要 |
A method for flue gas desulfurization in which sulfur oxides in the flue gas are converted into powdery ammonium compound, including providing an aqueous ammonia spraying device configured to atomize aqueous ammonia into droplets, cooling flue gas containing sulfur oxides down to a temperature between a saturation temperature of water and 80° C., adjusting the aqueous ammonia spraying device such that the aqueous ammonia is atomized into droplets having a Sauter mean diameter of 0.5 mum to 30 mum, and spraying the aqueous ammonia into the flue gas which has been cooled in the cooling step.
