Abstract

The present invention proposes a technique for lowering temperature gradient by higher purge flow in a gas turbine compressor rotor. The technique includes routing the purge flows to attain higher flow or heat transfer requirement for lowering temperature gradient. Alternate purge circuits are routed through clocked purge slots.

TECHNIQUE OF ROUTING FOR RELIABLE PURGE FLOWS

BACKGROUND

The present invention relates generally to a gas turbine compressor rotor and more particularly to a technique of routing a purge flow in the gas turbine compressor rotor.

Generally, higher purge flows are required in a gas turbine compressor rotor to meet heat transfer requirement of lowering temperature gradients.

A conventional technique includes routing circuit card assembly (CCA) through a plurality of axial holes in an inertia belt. However, the conventional technique does not acquire higher purge flow requirement.


It would be desirable to have an efficient technique to acquire higher purge flow requirement in the gas turbine compressor rotor.

DETAILED DESCRIPTION

The present invention proposes a technique for lowering temperature gradient by a higher purge flow in a gas turbine compressor rotor. The technique includes routing the purge flows to attain higher flow or heat transfer requirement for lowering temperature gradient. Alternate purge circuits are routed through clocked purge slots. Consequently, such an arrangement allows the circuits to be independent of each other with no dilution. Figure 1 depicts routing for purge flow in the gas turbine compressor rot...
