Experimental Study on Total Flooding Extinguishing Test by New Ultra-fine Water Mist Fire Extinguisher Extinguishing Combustion of Paper

This paper introduced a new kind of ultra-fine water mist extinguisher, and study on total flooding extinguishing test of ultra-fine water mist extinguishing combustion of paper in confined space with the size of 2.4m×2.4m×3.5m. The results showed that the ultra-fine water mist extinguisher with the mist flux of 500ml/min was effectively in extinguishing combustion of paper in confined space. Therefore, the device can be used to put out fire in archives room.
