摘要： PROBLEM TO BE SOLVED: To ensure the stable idle running operation by letting the leaked water stored in an outer peripheral part of a runner chamber escape into a casing from a guide vane in a slightly opened state, and draining the leaked water escaped to the casing into a draft tube through a casing drain tube in the idle running operation of a runner. SOLUTION: In the case where a hydraulic machine is changed to an idle running operation, a guide vane 7 and an inlet valve 14a are fully closed. Then an air supply valve 16a is opened, and the compressed air is introduced from a compressed air supply pipe 16 to a runner chamber 8 in order to press a water surface 9 of the runner chamber 8 down to a draft tube 2. After the inlet valve 14a is fully closed, a casing drain valve 13a is opened to start the draining from a casing drain tube 13 to a draft tube 2. In the idle running operation of a runner 10, the guide vane 7 is slightly opened, so that the stored water 11 between the runner 10 and the guide vane 7 is made to escape to a casing 12 from an opening gap of the guide vane 7 to be drained to the draft tube 2 through the casing drain tube 13.

SOLUTION: A gas turbine plant 7 generates the gas turbine driving combustion gas (main current gas) by raising pressure of the sucked atmospheric air AR with an air compressor 8 and supplying this high pressure air to a gas turbine combustor 9 for combustion with the fuel F from a fuel section 12. This main current gas is supplied to a gas turbine 10 for expanding work so as to drive a machinery 11 to be driven such as a generator. In this case, the fuel section 12 is formed so that the fuel in a fuel tank 13 is supplied to the combustor 9 by a fuel pump 14 through a fuel valve 15 and a heat exchanger 16 arranged inside of the air compressor 8. High pressure air of the air compressor 8 is used for a heat source in the heat exchanger 16 for heating the fuel.
