PURPOSE:To make the starting of a compressor performable with the irreducible minimum of energy without fail, by feeding the compressor with a starting ags from the inlet side, while decreasing the feed pressure by degrees in proportion to an increase in the heat energy quantity given to the inlet side of a turbine. CONSTITUTION:In time of starting, a charging valve 3 is closed, while a control valve 13 for a starting gas feed device 9 is opened instead. With this constitution, a high pressure starting gas discharged out of a high pressure gas source 11 is fed to an inlet 1a of a compressor 1 and simultaneously the starting ags passing through the compressor 1 is led into an inlet 2b of a turbine 2 whereby both the turbine 2 and the compressor 1 get rotating. Under this condition, it the amount of heat energy given from an air chamber 7 of a fuel cell 6 and a combustion furnace 8 to the side of the turbine inlet 2b is gradually increased, power of the turnbine 2 increases. With increment of the heat energy quantity, opening of the control valve 13 is gradually decreased, and at the point that feed pressure drops up to atmospheric pressure, the charging valve 3 is opened and made to change over to self-excitation. |
