Abstract: 1,059,917. Gaseous seals. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 20, 1964 [Oct. 24, 1963], No. 42026/63. Heading F2B. [Also in Division F1]  In a steam turbine having a sub-atmospheric pressure stage 1 provided with a low pressure steam sealing gland 2, steam supplied to the gland is desuperheated before entering the gland by heat exchange with condensate of steam discharged from the turbine. Superheated steam from the turbine boiler is supplied through pipe 15 to the high pressure sealing gland 14 and to one end of a heat exchange coil 7 connected at its other end by pipe 5 to the low pressure sealing gland 2. Steam from the glands 2 and 14 is discharged to a chamber 8 where it is condensed by a coil 10 through which cooling liquid, e.g. feed water for the turbine boiler, is circulated. The chamber 8 is vented to atmosphere at 9 and the level 11 of the condensate in the chamber is controlled by a ball valve actuating a drain valve 13. Superheated steam passing through the coil 7 is thus desuperheated by heat exchange with the condensate in the chamber before being fed through pipe 5 to the gland 2. Steam from the condensate due to this heat exchange action is again condensed by the coil 10. The vent 9 may be replaced by a pressure release valve or a restricted orifice to maintain the pressure in chamber 8 above atmosphere.
