Abstract
Abstract An industrial gas tubine power plant consists of a gas generator having a compressor, combustion equipment and a compressor driving turbine, and a power turbine. The stator casing of the power turbine is attached to the gas generator and the rotor portion of the power turbine is mounted independently in an overhung manner in a pedestal. The gas generator is mounted at the rear on a pair of trunnions on the stator casing and at the front either by a link attached to an overhead frame or a pair of links from a column on each side of the gas generator. The gas generator also has a central locating device mounted under the stator casing to centralise radial expansion of the stator casing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
100 words
A gas turbine power plant including a gas generator and a power turbine, the stator portion of the power turbine being secured to the gas generator and the rotatable portion of the power turbine being mounted in support means which are independent of the gas generator and the stator portion of the power turbine, the power turbine stator portion being mounted for rotation about a horizontal axis on a pair of trunnions, one of said trunnions being mounted on each side of the power turbine stator portion, the upstream end of the gas generator being mounted on a movable support.
Claim 2
Dependent Claim
100 words
A gas turbine power plant including a gas generator and a power turbine, the stator portion of the power turbine being secured to the gas generator and the rotatable portion of the power turbine being mounted in support means which are independent of the gas generator and the stator portion of the power turbine, the power turbine stator portion being mounted for rotation about a horizontal axis on a pair of trunnions, one of said trunnions being mounted on each side of the power turbine stator portion, the upstream end of the gas generator being mounted on a movable support.
Claim 3
Dependent Claim
90 words
A power plant as claimed in claim 1 in which a central locating means is secured to the power turbine stator portion, the central locating means comprising a tongue engaging a slot in a member which is secured to the ground, a stop being provided at one end of the slot and so positioned as to allow the stator portion to move due to thermal expansion but to prevent fouling between the stator and rotor portions of the power turbine when the stator portion is disconnected from the gas generator.
Claim 4
Dependent Claim
45 words
A power plant as claimed in claim 1 in which the upstream support of the gas generator comprises a pair of columns, one on each side of the gas generator and an arm pivotally attached at each end between the gas generator and each column.
