| Abstract: | In order to investigate mechanism and application advantages about semi-dry desulphurization,a performance study of SO 2 removal and NO X removal is carried out upon a 35 t/h coal burning boiler.Experiences conducted to estimate the contents of the experiment include the effects of discharging flue gas temperature,Ca/S molar ratio and mass recriculating fly-ash on the removal of SO 2 and NO X.Testing results show that desulphurization efficiency is attained as high as 85.1% with Ca/S molar ratio is less than 1.2,and 88.3% of SO 2 removal efficiency when Ca/S molar ratio is 1.4.With desulphurization efficiency of 81.07%,denitrification efficiency of 63.9%,and dedusting efficiency of 97.7% are achieved when mass recirculating fly-ash to lime ratio is 4∶1,and Ca/S molar ratio is 1.15. |
