Title:
SEAL STRUCTURE OF GAS TURBINE FLANGE SEALING FACE
Document Type and Number:
Japanese Patent JP3310907
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas turbine flange sealing face of improved seal property by elaborating the flange sealing face constitution.
SOLUTION: This highly reliable gas turbine is obtained by improving seal property of a flange sealing face 7 of the gas turbine including a steam cooling structure conjointly with labyrinth effect and high bearing obtainable by reducing the flange sealing face 7 area by means of composing a seal structure on the gas turbine flange sealing face 7 by providing a groove 8 of plurality of labyrinthine stripes on at least side of the flange sealing face 7.
