Abstract
637,771. Steam turbines. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. June 1, 1948, No. 14795. Convention date, June 2, 1947. [Class 110(iii)] Segmental nozzle boxes 22, Fig. 1. are formed with tubular inlet necks 33 and are each secured to the casing by a conical collar 46 of which one end is welded at 47 to the neck 33 and the other end is welded at 48 to the casing. In the structure of Fig. 1 there are five segments with parallel necks. Two are secured to one casing half and three to the other. The segments in each group have interengaging radial tongues and grooves and are positioned in the casing by circumferential tongues and grooves 50. Fig. 3 shows a structure with six segments carried by an inner casing 58. The tubular necks 33 are secured to the inner casing by collars 46 and have pistonlike ends, fitted with packing rings 74, which lie in bushes 73 in tubular continuations 68 welded in place in the outer casing 56. The nozzle boxes have peripheral tongue and groove connections 50 with'the inner casing and radial connections 53 between the boxes of each set of three. Fig. 6 shows a form of a continuation 68 having a bell skirt 76b welded to the outer casing at 77a. The skirt may be replaced by collar similarly situated and welded to the continuation.
