Abstract

1343457 Minimising fires in.fuel tanks PARKER-HANNIFIN CORP 23 April 1971 [11 May 1970] 11134/71 Heading ASA An inerting system for an inflammable fluid in a container, e.g. aircraft fuel tank 17, comprises dewar 10 fitted with pressure relief valve 12 and containing a liquid at cryogenic temperature and under its own vapour pressure, e.g. N 2 at -205‹C to -195‹C and 2-5 kg/cm<SP>2</SP>, connected by conduit 15 via control valve 21 to fog nozzle 35 positioned in ullage 16 above fuel 18. Valve 21 is normally closed and is associated with operating device 22 which is automatically actuated by fire detectors 23, 24 and control unit 25, and with operating device 28 which is actuated by manual operation of switch button 29. Unit 25 may include a timer to close valve 21 after a predetermined period. Check valve 33 is provided upstream of nozzle 35 and one-way vent valve 38 prevents overpressurising of tank 17. Ullage 16 contains fuel vapour, oxygen from the atmosphere or released from the fuel, and possibly gaseous N 2 . If the O 2 content exceeds 11% and ignition of the ullage gas occurs, detectors 23, 24 open valve 21. Liquid N 2 is sprayed from nozzle 35 in droplets and on vaporising dilutes and cools the ullage gases to the point where combustion stops. Valve 21 can also be opened by button 29 if manual control is required. Conduit 15 is chosen with diameter and length to ensure that N 2 reaches nozzle 35 at least partly in liquid form.
