Formation Characteristics of Aerosol Particle in Wet Ammonia Desulfurization Process

摘要

1. A large amount of aerosol particles produced during WFGD processes. NH_3·H_2O > (NH_4)2SO_3 > (NH_4)2SO_4rn2. The aerosol particles are mostly in submicron size range and the main components were (NH_4)2SO_3, NH_4HSO_3, (NH_4)2SO_4 and NH_4HSO_4, etc.rn3. The optimum operating conditions were as follows: T_L=50℃, the mass concentration of desulfurizing agent 10%, L/G=10～15L/Nm~3, pH value of 11, 7.0 and 8.0 for NH_3·H_2O, (NH_4)_2SO_4 and (NH_4)2SO_3, respectively.
