Abstract

618,133. Axial-flow pumps; elastic-fluid turbines; stuffing-boxes. AKTIEBOLAGET COTAVERKEN. Oct. 24, 1946, No. 31612. Convention date, Jan. 25. [Classes 110 (i), 110 (iii) and 122 (v)] An arrangement in compressors driven by turbines particularly for power plants in which the turbine is driven by exhaust steam from a multi-stage reciprocating steam engine and in which the compressor is used for compressing the steam between some of the expansion stages of the steam engine, is characterised in the provision of means for supplying leaking steam from at least one of the shaft packings of the compressor as sealing steam to one or more packings of the turbine and if desired to the steam inlet of the turbine. Conduits 9, 11 supply steam leaking from the packings 6, 7 of the compressor 1 to the packing 8 of the turbine 2 via conduit 12. An automatically adjustable valve 10 which is controlled by the steam pressure in the conduits 9, 11 and 12 admits steam to the inlet 2 of the turbine via conduit 20 if the pressure is too high and allows live steam to be admitted via conduit 19 if the pressure is too low. Live steam may also be admitted to the ejector 22 to draw off any excess of steam from the outer ends of packings 6, 8.
