주방열차내 화재 특성에 관한 수치해석적 연구 - KTX 식당칸

초록

In 2010, a new modeled KTX train will operate kitchen carriage which supplies cooked dish. A kitchen is an easy place to occur a fire because of the characteristic of the cooking oil. But the research is lack about a cooking fire in a new modeled KTX train, still fire prevention manual dose not exist about new modeled kitchen in KTX train. The study is performed to investigate the characteristics of the large cooking fire in KTX kitchen carriage. Through an analysis about the temperature variation of fire plume and heat release rate, we investigate the characteristic of cooking oil fires and performance of the suppression by water mist system. From the result, we find out the improperness of a present automatic sprinkler system and suggest new automatic sprinkler system and detector location
