Title:
POWER GENERATION SYSTEM AND METHOD FOR COOLING FUEL CELL EXHAUST IN POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/073547
Kind Code:
A1
Abstract:
The purpose of the invention is to protect the temperature of an exhaust stream in an exhaust line for carrying the exhaust stream, even if an event occurs in which the temperature of the exhaust stream discharged from a fuel cell exceeds temperature during rated operation. A power generation system has: an SOFC (13); an exhaust air line (34) or an exhaust fuel line (43), said exhaust air line (34) and said exhaust fuel line (43) carrying exhaust air (A3) and exhaust fuel gas (L3) discharged from the SOFC (13), respectively; a temperature detector (67) for detecting the temperature of the exhaust air (A3) or the exhaust fuel gas (L3) discharged from the SOFC (13) or the temperature of the exhaust air line (34) or the exhaust fuel line (43); an exhaust cooling device (61) for cooling the exhaust air (A3) in the exhaust air line (34) or the exhaust fuel gas (L3) in the exhaust fuel line (43); and a control device (62) for activating the exhaust cooling device (61) when the temperature detected by the temperature detector (67) exceeds a predetermined temperature.
