Abstract
Official abstract text for this publication.
An axial flow gas turbine ( 20 ) includes a rotor ( 13 ) and a stator, and a hot gas path through which hot gas passes. The rotor ( 13 ) includes a rotor shaft ( 15 ) with axial slots for receiving a plurality of blades (B 1 -B 3 ) arranged in a series of blade rows, with rotor heat shields (R 1 , R 2 ) interposed between adjacent blade rows. The rotor shaft ( 15 ) is configured to axially conduct a main flow of cooling air along the rotor heat shields (R 1 , R 2 ) and the lower parts of the blades (B 1 -B 3 ), and the rotor shaft ( 15 ) supplies the interior of the blades (B 1 -B 3 ) with cooling air ( 18 ). Stable and predictable cooling air parameters at any blade row inlet are secured by providing air-tight cooling channels ( 21 ), which extend axially through the rotor shaft ( 15 ) separate from the main flow of cooling air ( 17 ), and supply the blades (B 1 -B 3 ) with cooling air ( 18 ).
First claim
Opening claim text (preview).
We claim: 1. An axial flow gas turbine comprising: a rotor and a stator, the stator forming a casing surrounding the rotor and forming a hot gas path through which hot gas formed in a combustion chamber can pass; wherein the rotor comprises a plurality of blades and a rotor shaft with axial slots configured and arranged to receive said plurality of blades arranged in a series of blade rows, and rotor heat shields interposed between adjacent blade rows, thereby forming an inner o…
