  • 307 Pilot Scale Boiler NO_x Control Using Indirect Plasma and Chemical Hybrid Process

抄録

The pilot-scale NO_x removal from boiler emission was performed using indirect plasma and a chemical hybrid process. The flue gas flow rate was in the range of 460〜1,430m^3_N/hr, and the gas temperature of 335℃, and NO_x concentration of approximately 50ppm for city gas firing. The NO_2 oxidized by the indirect plasma was further reduced by a Na_2SO_3 solution chemical scrubber to N_2. The NO_x removal efficiency exceeded 90%.
