Embodiment Construction

[0018] The subject is a turbine 1 comprising at least one rotor assembly 10 and at least one compressor housing 11 . Turbine 1 is a gas turbine. Combustion exhaust gas is the working fluid of the gas turbine 1 for driving the rotor assembly 10 of the turbine 1 .

[0019] The compressor housing comprises at least one inner compressor housing chamber 1112 for arranging the rotor assembly and at least one outer compressor housing chamber 1113 for compressor discharge air extraction. The rotor assembly is located in the inner compressor housing cavity such that the rotor assembly and the compressor housing are arranged coaxially with each other. These elements comprise a common axis of rotation 12 .

[0020] The inner compressor housing chamber 1112 and the outer compressor housing chamber 1113 are separated from each other by a partition housing wall 1101 . The outer compressor casing chamber 1113 includes at least one bounding casing wall 110 . The boundary housing wall 110 ...

Abstract

A gas turbine is provided comprising at least one rotor assembly (10); and at least one compressor casing (11); wherein the compressor casing comprises at least one inner compressor casing chamber (1112) for arranging the rotor assembly and at least one outer compressor casing chamber (1113) for tempering the compressor casing; the inner compressor casing chamber (1112) and the outer compressor casing chamber (1113) are separated from each other by a separating casing wall (1101); the outer compressor casing chamber (1113) comprises at least one boundary casing wall (110); the boundary casing wall (110) and the separating casing wall (1101) are oppositely spaced from each other such that the outer compressor casing chamber is formed; and the boundary casing wall (110) comprises at least one inlet opening (1100) for leading in an inlet tempering gas flow (1115) with tempering gas into the outer compressor casing chamber (1113) such that a tangential material temperature variation of the compressor casing (11) is reduced in comparison to a non tempered compressor casing. Preferably more inlet openings (1100) are distributed alongside an internal surface of the boundary casing wall (110).

Description

technical field [0001] The invention relates to a gas turbine with a compressor housing and to the use of the gas turbine. Background technique [0002] A gas turbine includes a rotor assembly (at least one movable part) and a compressor housing (at least one stationary part). A rotor assembly is driven by working fluid through the gas turbine and is positioned within the compressor housing. [0003] Thermal stratification of the inner chamber (cavity) of the compressor housing is often observed in industrial gas turbines. This phenomenon is often observed shortly after a gas turbine shutdown. In the housing, a temperature difference can be observed. The temperature differential causes the compressor casing to deform laterally relative to the rotor assembly of the turbine. As a result, friction of the rotor assembly on the inner surface of the housing may occur. Contents of the invention [0004] It is an object of the present invention to provide a turbine which redu...
