GAS TURBINE PLANT

摘要

The invention relates to gas turbine plants which can be used for gas turbine locomotives and mobile and stationary power plants and which use cryogenic gas fuel. The oil systems of a gas turbine engine and of actuating units are designed in the form of individual adjustable flow circuits each of which comprises fuel-oil heat exchangers, the cooling medium of which is in the form of a cryogenic gas fuel, a delivery pump and an oil tank. The cooling cavities of the fuel/oil heat exchangers are connected, at the inputs thereof, to a fuel supply and adjusting device and to a fuel heater, which is arranged, at the outputs thereof, in the sleeve of the gas turbine engine. Said invention makes it possible to design a low-consumption gas turbine plant provided with a small-sized oil-cooling and fuel-heating system.; The invention makes it possible to recover the heat removed by oil from lubricated friction units of the gas turbine engine and the actuating units driven thereby and to return said heat to the thermodynamic circuit of the gas turbine engine. In addition, the power consumption for needs of the gas turbine plant is reduced, the structural design for the oil cooling system is substantially simplified and the fuel heater can be of small size due to the fact that a cryogenic gas is heated in the fuel/oil heat exchangers.
