Abstract
660,969. Turbines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 4, 1949 [Nov. 2, 1948], No. 25452/49. Class 110(iii) A steam turbine provided with impulse blading at its high-pressure end comprises a circular arrangement of nozzle boxes 10 having nozzle blocks 20 and vanes 25, 25a provided with nozzle passages 11, 11a and means, such as a bolted bridging structure 22, connecting each block to its box so that the discharge of steam therefrom is restricted to the passages 11, 11a, wherein the vane 25a separating the end nozzle passage 11a of one block from the adjacent passage 11 of a second block comprises components 27, 28'which are respectively carried by the adjacent blocks and separated by a clearance space 29 which extends generally in the same direction as the nozzle passages and opens through a convex face of the composite vane 25a at the downstream side of the nozzle passage 11c bounded by said face and the box connecting means comprises adjacent wall elements 31, 32 which are connected, e.g. welded, to the components 27, 28 respectively and separated by a clearance space 33. The opposed lips 40, 41 of the components 27, 28 are in a plane normal to the turbine axis. The blading comprises blades 12, 14 of a rotor 15 and a stator blade 16.
