Abstract

754,580. Elastic-fluid turbines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO . May 14, 1954 [May 20, 1953], No. 14146/54. Class 110(3) An elastic-fluid turbine comprises inner and outer casings between which are longitudinal passages open to the low-pressure end of the turbine, working fluid inlets extending laterally through the casings adjacent the high-pressure end, and an exhaust outlet formed in the outer casing adjacent, the high-pressure end so that working fluid discharged from the turbine flower over the longitudinal extent of the inner casing for cooling purposes. Steam passes through two sets of inlet pipes 25, 26, 27 which extend through the outer casing 10 and inner casing 11 to two sets of nozzle boxes 33, 34, 35. After passing through impulse blading 13, the steam flows through passages 39 between the nozzle boxes to reaction blading 14, 14a and is exhausted through spaces 22 between the casings to an outlet 23. The steam cools adjacent hot parts as it flows through the passages 39 and spaces 22. Steam is extracted at 45 between the sets of blading 14 and 14a and taken through a connection 46. Steam leaking between packings 17, 18 is taken through pipes 48 to the extraction point 45.
