POWER GENERATION SYSTEM

摘要

A power generation system provided with: a gas turbine (11) having a compressor (21) and a combustor (22); a SOFC (13); a first compressed air supply line (26) that supplies compressed air (A1) compressed by the compressor (21) to the combustor (22); a second compressed air supply line (31) that supplies a portion (A2) of the compressed air compressed by the compressor (22) to the SOFC (13); an exhaust air supply line (36) that supplies exhaust air (A3) discharged from the SOFC (13) to the combustor (22); a first fuel gas supply line (27) that supplies a fuel gas (L1) to the combustor (22); a second fuel gas supply line (41) that supplies a fuel gas (L2) to the SOFC (13); an exhaust fuel gas supply line (45) that supplies an exhaust fuel gas (L3) discharged from the SOFC (13) to the combustor (22); and a heat exchanger (61) serving as a heating device for heating the fuel gas (L1) supplied to the combustor (22) through the first fuel gas supply line (27).
