POWER GENERATION SYSTEM AND METHOD FOR OPERATING POWER GENERATION SYSTEM

摘要

A power generation system (100) includes: a combustor (1) configured to combust a fuel; a power generation unit (50) configured to utilize energy obtained from the combustor (1) when generating electric power; a fuel supply unit (19) configured to supply the fuel to the combustor (1); an air supply unit (9) configured to supply combustion air to the combustor (1); a discharged gas passage (3) through which a discharged gas from the combustor (1) flows; a CO detector (4) configured to detect CO in the discharged gas; a temperature detector (6) configured to detect a temperature of the discharged gas; and a controller (7) configured to, when the discharged gas is flowing through the discharged gas passage, performs at least one of an operation of detecting an abnormality of the discharged gas passage (3) based on a difference between detected temperatures of the temperature detector (6) relative to a difference between heated amounts of the discharged gas heated by a heater and an operation of detecting the abnormality of the discharged gas passage (3) based on the difference between the detected temperatures of the temperature detector (6) relative to a difference between outputs of at least one of the fuel supply unit ( 19) and the air supply unit (9).
