摘要

Low-temperature SCR denitration in new style PC kiln was conducted using TiO_2 catalyst. First, the theoretical quantity of ammonia consumption was calculated and applied in this experiment. Maintain the volume of exhaust gas flow and ammonia consumption quantity, concentration of NO_x reduced from initial 503 mg/Nm~3 of 120°C to 57.5 mg/Nm~3 of 170°C after catalytic reaction. When excess ammonia was injected into SCR reactor, efficiency of the denigration increased linearly too with temperature increasing and achieving the maximum of 89.45% under conditions of 170°C, ammonia flow rate of 4.00 SL/min. After 20h continuous operating, efficiency of the denigration fluctuated ± 1% only. Pore of TiO_2 catalyst have not blocked by exhaust smoke, that is to say: Low-temperature SCR TiO_2 catalyst can be long-term used in new style PC kiln.
