To provide a method for predicting whitening of sintering main exhaust gas, that can accurately predict whitening.SOLUTION: Provided is a method for predicting whitening of sintering main exhaust gas, comprising performing a measurement step S1 in which an aerosol concentration in sintering main exhaust gas is measured by conducting sintering experiment under an operating condition scheduled to be applied to actual machine, and a predicting step S2 in which, based on the correspondence relation between an aerosol concentration in sintering main exhaust gas and a whitening of sintering main exhaust gas, the level of whitening of sintering main exhaust gas when a sintering operation is performed under the operating condition scheduled to be applied to actual machine is predicted.SELECTED DRAWING: Figure 1 【課題】白色化を精度よく予測できる焼結主排ガスの白色化予測方法を提供すること。【解決手段】実機に適用予定の操業条件で焼結実験を行って焼結主排ガス中のエアロゾル濃度を測定する測定工程Ｓ１と、焼結主排ガス中のエアロゾル濃度と焼結主排ガスの白色化の対応関係に基づいて、実機に適用予定の前記操業条件で焼結操業を行う際の焼結主排ガスの白色化の程度を予測する予測工程Ｓ２と、を実施することを特徴とする焼結主排ガスの白色化予測方法。【選択図】図１
