The present invention relates to a method for measuring an unburned carbon content in coal ash, which includes the steps of: transmitting a signal with a predetermined frequency to the coal ash; receiving the signal passing through the coal ash; measuring a phase angle of the received signal; and calculating the unburned carbon content included in the coal ash, thereby quickly analyzing the unburned carbon content in the coal ash by using a frequency phase angle in the measurement and analysis of the unburned carbon content in the coal ash. 본 발명은 석탄회 미연탄소함량 측정 방법에 관한 것으로 소정의 주파수를 가지는 신호를 석탄회에 송신하는 단계, 상기 석탄회를 통과한 신호를 수신하는 단계, 상기 수신한 신호의 위상각을 측정하는 단계, 및 상기 측정된 위상각을 이용하여 상기 석탄회에 포함된 석탄회 미연탄소 함량을 산출하는 단계를 포함함으로써, 석탄회 미연탄소함량을 측정 분석함에 있어서, 주파수 위상각을 이용함으로써 빠른 시간 내에 분석이 가능하다.
