Zusammenfassung:The present invention provides a combustion characteristics estimation method of a blast furnace pulverized coal using a Raman spectrum. The combustion characteristics estimation method of a blast furnace pulverized coal using a Raman spectrum comprises the following steps of: measuring Raman spectrums of a plurality of estimation-targeted pulverized coals; calculating spectrum excitation coefficients from the Raman spectrums; measuring a combustion start temperature and a combustion finish temperature of each of the estimated-targeted pulverized coals; obtaining a first correlation between the spectrum excitation coefficients and the combustion start temperatures of the estimation-targeted pulverized coals; and obtaining a second correlation between the spectrum excitation coefficients and the combustion finish temperature of the estimation-targeted pulverized coals. According to the present invention, combustion characteristics of the pulverized coals can be estimated rapidly. 본 발명은, 라만 스펙트럼을 이용한 고로 미분탄의 연소특성 평가방법을 제공한다. 상기 라만 스펙트럼을 이용한 고로 미분탄의 연소특성 평가방법은, 복수의 평가대상 미분탄들의 라만 스팩트럼들을 측정하는 단계; 상기 라만 스팩트럼들로부터 스펙트럼 들뜸 계수들을 산출하는 단계; 상기 평가대상 미분탄들 각각의 연소 시작 온도와 연소 종료 온도를 측정하는 단계; 상기 스펙트럼 들뜸 계수들과 상기 평가대상 미분탄들의 연소 시작 온도의 제1 상관관계를 취득하는 단계; 및 상기 스펙트럼 들뜸 계수들과 상기 평가대상 미분탄들의 연소 종료 온도의 제2 상관관계를 취득하는 단계;를 포함한다.
