Gas turbine and corresponding gas or steam turbine plant

摘要

#CMT# #/CMT# The gas turbine has a set of hollow cone-shaped or hollow cylindrical components e.g. vane support (16), arranged coaxially inside one another. One of the components includes elliptical-shaped cross-sectional surface in an idle state. Lengths of major and minor axes of the elliptical-shaped cross-sectional surface are selected in such a manner that the component includes a circular cross-sectional surface by thermal deformation in an operating state. The component includes an upper segment (24) and a lower segment (26). #CMT#USE : #/CMT# Gas turbine for use in a gas turbine system and a steam turbine system (claimed) and for actuation of a generator and a working machine. #CMT#ADVANTAGE : #/CMT# The hollow cone-shaped or hollow cylindrical components are arranged coaxially inside one another, where one of the components includes the elliptical-shaped cross-sectional surface in the idle state, thus achieving a gas turbine with high efficiency, while maintaining high operational safety and service life of the gas turbine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows cross-sectional views of a vane support of a gas turbine in an idle state. 16 : Vane support 24 : Upper segment 26 : Lower segment 28 : Flanges 30 : Connecting joints.
