Title:
POWER GENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2014139424
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make it possible to ensure stable combustion in a gas turbine combustor and improve power generation efficiency by appropriately combusting fuel gas other than exhaust fuel gas discharged from a fuel battery in a power generation system.SOLUTION: A power generation system includes: a gas turbine 11 that includes a compressor 21 and a combustor 22; an SOFC 13; a first compressed-air supply line 26 supplying compressed air A1 compressed by the compressor 21 to the combustor 22; a second compressed-air supply line 31 supplying a part of compressed air A2 compressed by the compressor 21 to the SOFC 13; an exhaust-air supply line 36 supplying exhaust air A3 discharged from the SOFC 13 to the combustor 22; a first fuel-gas supply line 27 supplying fuel gas L1 to the combustor 22; a second fuel-gas supply line 41 supplying fuel gas L2 to the SOFC 13; an exhaust fuel-gas supply line 45 supplying exhaust fuel gas L3 discharged from the SOFC 13 to the combustor 22; and a heat exchanger 61 serving as a heater heating the fuel gas L1 supplied to the combustor 22 through the first fuel-gas supply line 27.
