Experimental Study on Fire Suppression and Smoke Control with Fine Water Mist in Confined Spaces
Abstract
To address the issue of horizontal spread of smoke during underground chamber fires, this paper proposes a method of fire prevention and smoke control using water mist. Experiments were conducted considering the nozzle positions, operating pressures, and ventilation
areas on the fire extinguishing effectiveness of the water mist. The experimental results indicate that when the nozzle is located at the top center, the fire extinguishing efficiency is the highest, with a fire extinguishing time of 7.5 seconds. The higher the operating pressure, the shorter
the fire extinguishing time for the water mist; the larger the ventilation area, the greater the impact on the fire extinguishing efficiency, and the
longer the fire extinguishing time. The experiments provide insights for the design of underground chambers and are significant for fire rescue
and evacuation of people.
