PURPOSE:To dispense with a hot blower by having all oxidic gases exhausted out of the cathode, while mixing the partial gas turned to low temperature and atmospheric pressure with air, compressing it for pressure up, and supplying it to the cathode, thereby recycling it. CONSTITUTION:At a supply line 9 for feeding the cathode 2 with oxidic gas, the air A compressed by a compressor 6 is led thereinto through a heat exchanger 7, but at this heat exchanger 7, heat exchange takes place between the compressed air and the exhaust gas discharged out of an exhaust gas turbine 5. And, the compressed air is preheated and fed to the cathode 2, while the exhaust gas turns to low temperature and atmospheric pressure and is discharged out and, after the partial gas is mixed with air at the suction side of the compressor 6, it is compressed for pressure up at the compressor 6, then it is referred to the cathode 2. With this constitution, it gets off without using the conventional hot blower in consequence. |
