摘      要：NH 3 activated electrode is placed in front of the electrode system of pulse corona discharge plasma. There are nozzles on the electrode. Positive DC high\|voltage is applied on the nozzle\|plate gap. NH\-3 is injected into the reactor through nozzles, at the same time, activated and treated. These nozzles were proposed in order to make the additional gas pass through corona discharge regions near the tip of nozzles and increase the mount of radicals. The aim is to improve the De\|SO\-2 efficiency by pulse discharge plasma in flue gas. The following topics are investigated and discussed in the paper: De\|SO\-2 effect of single NH\-3\|activated electrode, De\|SO\-2 effect of activated NH\-3, the relationship between stoichiometric ratio of NH\-3 to SO\-2 and De\|SO\-2 effect of activated NH\-3, mechanism of activated NH\-3 De\|SO\-2 effect. The experimental result indicates that the De\|SO\-2 efficiency can be increased 5%—10% by activated NH\-3 on the original base of De\|SO\-2 efficiency.
