Abstract
The present invention provides a plasma injector wherein a reducing agent injected from an injection port (19) at the distal end portion of an injection nozzle (18) is at least partially converted into a plasma; an exhaust gas purifying system; and a method for injecting a reducing agent. Using the plasma injector, the exhaust gas purifying system, and the method for injecting a reducing gas of the present invention, it is possible to vaporize a reducing agent supplied in an injection manner and/or to provide a highly reactive reducing agent from the reducing agent.
Claims14
A plasma injector for injecting a reducing agent,
- wherein said plasma injector comprises a injection nozzle and a plasma generator which generates a plasma in the vicinity of a injection port at the distal end portion of said injection nozzle;
- wherein said plasma injector injects a reducing agent in a liquid droplet state, and at least partially converts the reducing agent injected in a liquid droplet state into a plasma to vaporize the reducing agent;
- and
- wherein said plasma generator is located on the distal end portion of said injecting nozzle.
