POWER PLANT OF GAS-TURBINE LOCOMOTIVE WITH RECOVERY OF HEAT Russian patent published in 2007 - IPC F01K15/02 

FIELD: railway transport.

SUBSTANCE: proposed power plant of gas-turbine locomotive with cooled turbine and recovery of heat contains gas-turbine engine with compressor, combustion chamber and turbine connected by gas duct with free turbine after which regenerative heat exchanger is installed whose input is connected through water pump with water tank. Design peculiarity of proposed power plant is that output of regenerative heat exchanger is connected through air cooling heat exchanger, steam turbine and heat exchanger-condenser, with water tank. Heat exchanger-condenser is installed in fuel main line after fuel pump. Turbine contains air cooling system of nozzle assembly and turbine runner which includes air takeoff pipeline after compressor, air cooling heat exchanger, manifold, nozzle assembly with inner spaces and deflector on turbine disk.

EFFECT: increased efficiency and reliability of power plant.
