Abstract

This study measured the AITs of n-butanol + n-decane system from ignition delay time (time lag) by using ASTM E659 apparatus. The AITs of n-butanol and n-decane which constituted binary system were $340^{\circ}C$ and $212^{\circ}C$, respectively. The experimental AITs of n-butanol + n-decane system were a good agreement with the calculated AITs by the proposed equations with a few A.A.D. (average absolute deviation).

본 연구에서는 ASTM E659 장치를 이용하여 가연성 혼합물인 n-butanol + n-decane 계의 발화지연시간과 AIT관계를 측정하였다. 2성분계를 구성하는 순수물질인 n-butanol과 n-decane의 측정된 최소자연발화 온도는 각 각 $340^{\circ}C$, $211^{\circ}C$였다. 그리고 n-butanol + n-decane계에서 측정된 발화지연시간은 제시된 식에 의한 예측된 발화지연시간과 적은 평균절대오차에서 일치하였다.
