Preliminary pilot plant tests of a corona discharge-electron beam hybrid combustion flue gas cleaning system

Pilot power plant tests of a corona discharge-electron beam hybrid combustion flow gas cleaning system have been conducted. Gas flow rate of the test loop is a heavy oil fired boiler flue gas with 1200 Nm/sup 3//h, and one electron beam generator (500 kV/spl times/30 mA) is used with a corona discharge ammonia radical injection system (60 kV/spl times/5 mA), SO/sub 2/, CO, CO/sub 2/, NH/sub 3/, NO, NO/sub x/ and O/sub 2/ gases are monitored. The results show that up to 85% of NO/sub x/ and 98% of SO/sub x/ in flue gases are removed under a corona discharge-electron beam hybrid operations with significant small amount of leaked ammonias from exhaust flue gases.
