Abstract Using additive to improve desulfurization efficiency in spray drying absorption flue gas desulfurization(SDAFGD) has many merits,such as simple operation,low cost and obvious effect.In this paper,the influence of HOOC(CH_2)_4COOH,CaCl_2,MgCl_2,NaCl on SDAFGD had been studied.The mechanism of improving desulfurization efficiency had been analyzed.The result indicated that the SO_2 removal efficiency was improved and the expenditure was reduced when additives were added into Ca(OH)_2 slurry in SDAFGD.
