Abstract
An experimental study has been carried out to investigate the possibilities of an industrial $N_2$ generator that it replace Halon series as a natural extinguishing system. And this study comparison design standard of gas series extinguishing system with natural extinguishing system. We manufactured simple protected enclosure for analyzing fire-extinguishing performance of the $N_2$ generator. As a $N_2$ gas is exhausted on protected enclosure, a various of Oxygen concentration is measured to analyze fireextinguishing performance experimentally. The results, in case of $100m^3$ protected enclosure and $5m^3$/min $N_2$ flow rate, the Oxygen concentration is decreased below 15% within 3 minutes. And so, the $N_2$ generator make full use of an suffocating extinguishing system.
