Title:
HYBRID POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/084525
Kind Code:
A1
Abstract:
Disclosed is a hybrid power generation system of a gas turbine and a fuel cell wherein power generation output and power generation efficiency are enhanced while controlling operation cost by utilizing a large quantity of wastewater produced from the fuel cell. Reaction product of a fuel cell (7), i.e. water, is collected in a water collection device (25) from exhaust gas of a gas turbine and steam generated from a steam generator (23) by utilizing exhaust heat of the gas turbine is introduced to a turbine (12) for driving a generator (13). Since the power generation system employs hybrid system not only in the aspect of heat but also in the aspect of utilization of water, output and efficiency of a power generation system can be enhanced. The invention especially exhibits great effect in a hybrid system of medium temperature SOFC where the exhaust gas temperature of the gas turbine becomes high. Furthermore, cost required for water supply can be controlled because water is not supplied externally to the system but the system utilizes wastewater of the fuel cell, and stream can be produced even in such a place or situation as water required for generation of steam cannot be introduced.
