Title:
VAPOR TURBINE COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/110322
Kind Code:
A1
Abstract:
Vapor turbines (120, 130, 140) are provided with: a cooling vapor passage (69Ba) which passes through a casing (62 (outer casing 62A and inner casing 62B)) along a superheated vapor supply pipe (69A) to reach a gap (65B); and a cooling vapor supply section (70) which extends through the cooling vapor passage (69Ba) along the superheated vapor supply pipe (69A) and reaches the gap (65B), the cooling vapor supply section (70) supplying cooling vapor (C) having higher pressure and lower temperature than superheated vapor (G) supplied by the superheated vapor supply pipe (69A). As a result of this configuration, cooling efficiency is improved.
