				Semi-dry reactor (S.D.R) system is used to evaluate the effect of spray characteristics for the removal of HCl in the flue gases, and in these experiment, the spray direction was co-current with flue gas and the two-fluid external mixing nozzle was used. And the HCl concentration of the treated flue gas was measured by the combustion gas analyzer (TMS system) on stack.  
In these experiment, we obtained the maximum removal efficiency of HCl in the incineration flue gas was 96% when atomization quantity of lime slurry was 600ℓ/hr and the Ca/Cl ratio was 3.36 and the slurry droplet size proved 24㎛. Also, the temperature of inlet flue gas into semi-dry reactor have to maintain over 300℃ since lower gas temperature can be caused condensing at the next bag filter.
