Abstract :
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 Nm3 /h, and one electron beam generator (500 kV×30 mA) is used with a corona discharge ammonia radical injection system (60 kV×5 mA), SO2, CO, CO2, NH3, NO, NOx and O2 gases are monitored. The results show that up to 85% of NOx and 98% of SOx in flue gases are removed under a corona discharge-electron beam hybrid operations with significant small amount of leaked ammonias from exhaust flue gases
