Extinguishment of Cooking Oil Fires by Water Mist Fire Suppression Systems   总被引:2,自引:0,他引:2  
A series of full-scale experiments were conducted in a mock-up commercial cooking area to study extinguishing mechanisms and effectiveness of water mist against cooking oil fires. The impact of water mist characteristics, such as spray angle, droplet size, flow rate, discharge pressure and type of nozzle, on the effectiveness of water mist against cooking oil fires was investigated. A series of oil splash experiments were also conducted to determine if the oil was splashed by water mist. In addition, the change in oil composition during heating and fire suppression was determined using Fourier Transform Infrared (FTIR) technique.The study showed that cooking oil fires were very difficult to extinguish, because they burned at high temperature and re-ignited easily due to changes in oil composition during heating and fire suppression. The water mist systems developed in the present work effectively extinguished cooking oil fires and prevented them from re-ignition. The spray angle, discharge pressure, and water flow rate were important factors to determine the effectiveness of water mist in extinguishing cooking oil fires.  相似文献

Water mist fire suppression systems are being seriously considered as replacements for Halon 1301 total flooding systems in machinery space applications. A total flooding water mist system is designed to discharge mist uniformly throughout the entire enclosure/compartment. The tests conducted to date form a substantial database for water mist systems installed in machinery spaces with volumes from 100 m3 to 1,000 m3 and varying degrees of ventilation. These tests have also identified the strengths and limitations of water mist in these applications. This report describes the capabilities of total flooding water mist fire suppression systems in machinery space applications.  相似文献

Due to the intense R&D activity in the field of water mist fire suppression during the past decade, the qualitative and quantitative understanding on the performance of water mist has increased significantly. This development has led to a point in which quantitative theoretical models describing large-scale water mist fire suppression systems begin to emerge. This paper describes the composition and validation of one such model, designed for total flooding water mist applications, especially against flammable liquid hazards in enclosures. The basic construction of the model is first described, followed by an example on the validation of the model using full-scale experimental data. The model is then used to investigate the limitations to the maximum possible mist concentration in the protected space. The potential of the model as an engineering tool is illustrated by making predictions on the scaling laws associated with water mist systems in the framework of IMO MSC/Circ.668/728 as the enclosure volumes and ventilation conditions are varied. The predictions are found to be in agreement with what is indicated by the recent US Coast Guard test series in very large machinery spaces.  相似文献
