Apparatus for discharging fire extinguishing agent to environment of e.g. tunnel during firefighting, has axial flow jet fans that are connected to extinguishing agent source through supply conduits for jet flow of extinguishing agent

摘要

The discharging apparatus has several axial flow jet fans (3-5) which are fixedly mounted to wall and ceiling in tunnel/building (1). The axial flow jet fans are connected to extinguishing agent source (7) through supply conduits (10-12) for jet flow of the fire extinguishing agent. An injection apparatus is provided for injecting the fire extinguishing agent to axial flow jet fan in axial and radial directions. An independent claim is included for a system for supporting firefighting in tunnel and building.
