Title:
POWER GENERATION SYSTEM AND METHOD FOR OPERATING POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/077156
Kind Code:
A1
Abstract:
The invention addresses the problem of providing a power generation system capable of effectively using the heat of the exhaust air discharged from an SOFC and also providing a method for operating the power generation system. The power generation system has a gas turbine, a fuel cell, an exhaust air circulation line, an exhaust fuel gas supply line, a turbine, an exhaust heat recovery boiler, and at least one exhaust air heat exchanger. The turbine is equipped with a high-pressure turbine, a medium-pressure turbine, and a low-pressure turbine. The exhaust heat recovery boiler is equipped with a high-pressure steam circulation mechanism, a medium-pressure steam circulation mechanism, and a low-pressure steam circulation mechanism. The exhaust air heat exchanger exchanges heat between the steam exchanging heat with the exhaust gas in the high-pressure steam circulation mechanism or the medium-pressure steam circulation mechanism and flowing toward the turbine and the exhaust gas flowing through the exhaust air circulation line, thereby increasing the temperature of the steam and decreasing the temperature of the exhaust gas.
