Abstract
5219. Akt.-Ges. Brown, Boveri, et Cie. Oct. 25, 1909, [Convention date]. Axial-flow type; balancing moving parts; reversing.-In combined ahead and astern turbines of the kind in which the two turbines are arranged on the same shaft with their exhaust ends adjacent and separated by a partition, the ahead turbine is provided with an impulse stage at its steam inlet followed by a reaction stage, the exhaust end of which carries a dummy piston, of the kind described in Specification 6435/04, subjected to the pressure of the steam delivered from the impulse stage, so that the propeller thrust is balanced. Ahead and astern turbines A, B are mounted on a common shaft, and their adjacent exhaust ends are separated by a partition a, which carries a packing b connected through chambers k to passages in the partition communicating with a lower pressure stage of another turbine, or with the atmosphere, or with the condenser. The ahead turbine A comprises impulse stages d and reaction stages f. Steam from the impulse stages is conducted through openings n to act on a dummy piston g, the areas of which are so arranged that the propeller thrust is balanced. Packing m is provided between the partition a and the exhaust end of the reaction stages.
