GAS TURBINE PLANT BLADES COOLING Russian patent published in 2016 - IPC F02C7/12 

FIELD: engines and pumps.

SUBSTANCE: turbine blades are cooled with the help of the cooling circuit. The cooling circuit consists of the electrically conducting circuit. The elements of the latter are arranged on the turbine structural elements to make the cathode by application of thermal emission ply on the blades of electrically conducting material emitting the electrons into working fluid at heating. Besides, the anode is fabricated and secured via the electric insulation ply inside the housing, for example, at the housing inner wall to take up the electrons of emission from the working fluid. Electrically conducting circuit is composed by serial connection of said anode with cathode via electric load, current pickup, shaft, rotor and turbine blade. Anode temperature is kept below the turbine blade emission ply temperature by anode cooling at its seat of the turbine structural element.

EFFECT: lower temperature of turbine blades, higher efficiency and reliability of the turbine.
