요약

대량의 비활성가스를 발생시키는 Inert Gas Generator(IGG)를 소화설비로 사용하기 위해 본 연구에서는 가스터빈을 채용한 IGG에서 발생되는 배기가스의 소화성능을 검토하였다. IGG에서 발생하는 가스는 조성을 동일하게 만든 모사 혼합가스를 이용하였으며, Cup Burner시험방법으로 소화농도를 측정하였다. 얻어진 소화농도를 NFPA 2001에서 권장하는 방법에 적용하여 소화설계 농도 및 소화공간 크기를 산정하였다. 또한, $2m imes2m imes2m$ 크기의 공간에서 화재진압 실험을 수행하여 실제 소화성능을 확인하였다.

Abstract

A study of the utilization of inert gas generator(IGG) that generates a large amount of inert gas for the fire extinguishing equipment was performed. In this study, the fire extinction performance of gas generated from a 1GG which is implemented to a gas turbine was investigated. A simulated mixture gas of which composition is the same as that of the gas generated from ICG was used in all experiments. First, the extinction concentration was measured using a cup burner method. The extinction design concentration and the volume of extinction space was calculated by applying the obtained extinction concentration to a method recommended by NFPA 2001. In practical respects, the fire extinction performance of IGG-generated gas was confirmed through the fire suppression experiment within a $2m imes2m imes2m$ room.
