Zusammenfassung:	To reduce an amount of discharged NOx in sintering exhaust gas.SOLUTION: A method for reducing NOx in a sintering exhaust gas is intended to reduce an amount of discharged NOx in a sintering exhaust gas discharged when sintered ore is manufacturing using a blended raw material including a plurality of brands of iron ores. The method includes monitoring an NOx concentration in the sintering exhaust gas, and decreasing an average crystal water content of all the iron ores included in the blended raw material by changing a blending ratio of the plurality of brands of iron ores when the NOx concentration in a monitoring sintering exhaust gas exceeds a predetermined threshold value.SELECTED DRAWING: Figure 1 【課題】焼結排ガス中のＮＯｘ排出量を低減する。【解決手段】複数の銘柄の鉄鉱石を含む配合原料を用いて焼結鉱を製造する際に排出される焼結排ガス中のＮＯｘ排出量を低減する焼結排ガスのＮＯｘ低減方法において、焼結排ガス中のＮＯｘ濃度を監視し、監視する焼結排ガス中のＮＯｘ濃度が所定の閾値を超えた際に、複数の銘柄の鉄鉱石の配合割合を変更して、配合原料に含まれる全鉄鉱石の平均結晶水含有量を低くする。【選択図】図１
