Abstract

1281613 Revaporizing liquefied gases SYSTEMS CAPITAL CORP 17 Feb 1970 [26 March 1969] 7507/70 Heading F4P Revaporization of liquid nitrogen stored in a tank 11 is effected by passing the gas into a chamber 12 containing preheated alumina pellets 14. The pellets 14 are heated prior to the supply of liquid by hot gas forced through the chamber 12 by a pump 41, the gas being heated over a burner in duct 19 of an exchanger 15. Vaporized N 2 is passed from chamber 12 via outlet 45, line 47 and valve 17 to the delivery coupling 49. Liquid N 2 may be supplied to chamber 12 by a pump, (Fig. 1, not shown), or by the vapour pressure within tank 11 which is increased by vaporizing same N 2 in coils 87 and 93 and returning the vapour to tank 11. Tank 11 is filled via a union 65 and valve 67 gases within the tank being vented; when the filling cycle is completed the venting valves are shut and the . pellets 14 heated until a predetermined temperature is reached whereupon heating ceases and liquid N 2 is supplied to the chamber 12. The hot high pressure gas generated may be delivered to the intake duct of an aircraft turbine engine for starting the engine. In an alternative embodiment, (Fig. 2, not shown), the revaporization unit is mounted in an aircraft, hot gas for heating the pellets being provided by the exhaust of a small turbine.
