Embodiment Construction

[0012] Referring now to the accompanying drawings, figure 1 A rotary machine is shown schematically (only a part is shown in this figure), wherein the rotary machine comprises a rotor 110, eg a turbine rotor, and a housing 120, eg a turbine housing. For example, rotor 110 is typically, but is not limited to, configured as a one-piece rotor or as two or more longitudinally connected rotor sections. The housing 120 is typically configured as an integral housing or as several longitudinally connected housing segments, but is not limited thereto. The term "rotor" as used herein includes shafts, disks, wheels and the like. The rotor 110 has a generally longitudinally extending shaft, and the housing 120 is generally coaxially aligned with the shaft. The housing 120 surrounds the rotor 110 in the circumferential direction and is spaced apart from the rotor 110 in the radial direction. Furthermore, the rotary machine includes an insert assembly 100 that thermally insulates the fri...

Abstract

The present invention provided an insert assembly 100 for a rotary machine containing a rotor 110 and a casing 120. The rotor 110 contains a generally longitudinally extending axis. The casing 120 is generally coaxially aligned with the axis. The casing 120 circumferentially surrounds, and is radially spaced apart from the rotor 110. The insert assembly 140 contains a channel 130 circumferentially disposed on the rotor 110 and the insert 140 circumferentially disposed in such channel 130 such that the insert assembly 110 is configured to thermally insulate frictional heat from the rotor 110 to the insert 140.

Description

technical field [0001] The present invention relates generally to rotating machines, and more particularly to a rotor insert assembly for rotating machines such as steam and gas turbines. Background technique [0002] Rotating machines include, but are not limited to, steam turbines, compressors, and gas turbines. A steam turbine has a steam passage that typically includes a steam inlet, a turbine, and a steam outlet in series flow relationship. A gas turbine has a gas passage that typically includes an air inlet (inlet), a compressor, a combustor, a turbine, and an outlet (or exhaust nozzle) in series flow relationship. Gas or steam leakage out of or into a gas or steam channel from a high pressure area to a low pressure area is undesirable. For example, any gas passage leakage within the turbine or compressor region of a gas turbine between the turbine or compressor rotor and the circumferentially surrounding turbine or compressor housing will reduce the efficiency of th...
