Experimental Study on Extinguishing Characteristics of Compressed Air - water Mist in Confined Space
Abstract：In order to apply water mist technology on coal combustion in mine, we proposes a new type of Compressed Air - Water Mist technology for mine fire prevention and extinguishing, which contains a two - phase flow atomization device that can produce water mist with compressed air. We built a small scale compartment with compressed air - water mist for restraining coal combustion in a confined space, then investigated the restraining efficiency and related factors. Then the study finds that compressed air - water mist has the potential to reduce the. intensity of coal combustion in confined space, lower the toxic and harmful gas, reduce suspended particulate matter and improve visibility. It can ensure the evacuation and fire rescue operation go with a swing.
