To investigate principal aspects of flue gas cleaning by pulsed corona energization process. To find design rules to reduce energy consumption and increase removal efficiency up to 70% for NOx and 80% for SO2 for this combined DeNOx/DeSOx method.
The principal tasks can be summarised as follows:
1) In situ investigations of pulsed corona discharge characteristics with a laboratory scale set-up: measurements of total light emission as a function of pulse parameters to determine the discharge mode; fast electrical measurements for calculation of the energy input; Schlieren photography and optical emission measurements to determine the radial and axial distribution of the streamer channels; spectroscopic investigations for the determination of electron energy and radical production.
2) Pulse generator scheme design: review of pulse generator philosophy; review of the state of the art in high power switch technology; detailed design of a pulse generator.
3) Pulse generator construction and testing: construction of a pulse generator; test of its reliability and global efficiency.
4) Review of the standards for radiated electromagnetic interference.
5) Review of the EMC design considerations.
6) Electrode structure: comparison of NOx and SO2 removal efficiency with different electrode structures.
7) Ammonia injection: comparison of the removal efficiency obtained by injecting gaseous ammonia and hydrated ammonia.
8) Size distribution of produced ammonia salts: measurement of the ammonia salts size distribution in the range of 0.01 to 0.5 microns by cyclone and diffusion battery techniques.
