Comparison of deluge and water mist systems from a performance and practical point of view
Fixed fire fighting systems (FFFS) are a relatively new technology in tunnels that has been researched intensively in the recent years. European approaches have strongly focused to water mist systems, but especially Asian and American approaches have traditionally focused to deluge systems, often also called as "sprinkler" systems. There has been lots of full scale fire test data available about how water mist systems perform with tunnel fires, but deluge systems have undergone only very few full scale tests. This paper will show full scale fire test experiments with both systems. This unique test series is the first one in the world where deluge and mist systems are compared in tunnels with full scale HGV fire scenarios. The tests were carried out in 2011 with a Class A HGV fire load. The paper summarises the differences and similarities of deluge and water mist FFFS in theory and practice. Both systems have important parameters like nozzle type, droplet distribution, flow rate and lay-out to determine that are greatly affecting to the performance.
