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, NO_x and O₂ gases are monitored. The results show that up to 85% of NO_x and 98% of SO_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
