中文摘要	To study the influences of methane on selective non-catalytic reduction (SNCR), the condition of flue gas composition was simulated on a drop tube furnace test rig, and the influences of a few of methane on SNCR temperature window, NO/sub x/ reduction efficiency and ammonia slip from 650 degrees C to 1150 degrees C were investigated, as well as reactivity of methane. Experimental results indicate that a few of methane additive to SNCR reaction could depress and widen the reaction temperature window, and increase DeNO/sub x/ efficiency at lower temperature. At the same time, ammonia reactivity is promoted and ammonia utility is improved which causes reduction of ammonia slip. Further more, the reaction speed would be fastened, and the residence time to complete reaction is shortened. However the maximal NO/sub x/ reduction efficiency decreases a little. Increase of ammonia could widen the temperature window and enhance NO/sub x/ reduction efficiency. Methane injected into SNCR reaction would be depleted at 950 degrees C bringing no second pollution.
