摘要
采用碎纸、棉绳和聚氨酯塑料试验火,在地铁站台进行初期火灾实体试验。模拟车站各种空调通风工况,研究分析点型火灾探测器在地铁车站镂空格栅吊顶上、下不同位置安装时的响应性,以及线型红外光束感烟探测器对不同类型火源的响应性,为地铁车站镂空格栅吊顶处火灾探测器的选型和设置提供了数据支持和设计依据。
This paper discusses initial-stage fire entity experiment in the subway station with test fire by lighting shredded paper, cotton rope and polyurethane plastic. Simulation of air conditioning and ventilation condition in the subway station is conducted to study and analyze the responsivity of point-type fire detectors when they are installed in different upper and lower positions in a hollow grille ceiling type subway station, and the responsivity of linear infrared beam smoke detectors to different types of fire sources so as to provide data support and design basis for the selection and set-up of fire detectors in a hollow grille ceiling type subway station.
