A　new　effervescent　atomized　water　mist　fire　extinguishing　equipment　was　developed　by　combining　the　characters　of　water　mist　and　effervescent　atomization.　A　series　of　wood　crib　and　gasoline　pool　fire　suppression　experiments　were　performed　using　the　equipment.　The　fire　extinguishment　time,　temperature　and　radiation　heat　flux　of　the　flame　were　measured,　and　then　the　process　of　putting　out　different　type　fire　was　analyzed.　A　wood　crib　fire　of　0.6A　can　be　put　out　in　180　seconds　using　water　mist　produced　by　effervescent　atomization　equipment.　Only　38　seconds　was　taken　to　suppress　a　gasoline　fire.　©　(2013)　Trans　Tech　Publications,　Switzerland.
