PURPOSE:To improve the efficiency of the transmission line terminal, by furnishing an expansion turbine, rotating it by the compressed air introduced from the outlet of an air preheater, and driving an air compressor. CONSTITUTION:An expansion turbine 10 to drive an air compressor 3 and an auxiliary air preheater 11 to heat the exhaust gas of the turbine 10 are furnished. The air is compressed at the air compressor 3, when, the temperature of the air rises because it is compressed adiabatically. Furthermore, the temperature of the compressed air rises more at an air preheater 4, through a heat exchange with a part of the exhaust gas from a cathode of an MCFC 1. The air from the outlet of the air preheater 4 rotates the expansion turbine 10 to drive the air compressor 3, while it is decompressed and cooled through the turbine 10. The exhaust gas of the expansion turbine 10 is heat-exchanged with the remaining exhaust gas from the MCFC 1 other than the gas used for the air preheater 4, and, the turbine exhaust gas is heated and then delivered to the cathode side of the MCFC 1, and at the same time, delivered to a reformer 2 as the air for combustion. |
