PROBLEM TO BE SOLVED: To provide wheel and bucket cooling methods that do not reduce cycle output capacity and efficiency.SOLUTION: A turbomachine includes a compressor configured to compress air received at an intake portion to form compressed air that exits into an outlet portion. A combustor is operably connected with the compressor, and receives the compressed air. A turbine is operably connected with the combustor, and receives a combustion gas flow from the combustor. The turbine has a plurality of wheels and a plurality of buckets, and receives compressor bleed off air to cool the plurality of wheels. A cooling system is operatively connected to the turbine, and includes a plurality of heat pipes attached to or embedded within the plurality of wheels. The compressor bleed off air is configured to impinge onto the plurality of wheels or the plurality of heat pipes. The plurality of heat pipes and the compressor bleed off air cool the wheels.SELECTED DRAWING: Figure 1 |
