POWER GENERATION SYSTEM AND METHOD FOR OPERATING POWER GENERATION SYSTEM

摘要

A power generation system (100) equipped with: a combustor (1) that burns a fuel; a power generation unit (50) that uses the energy obtained by the combustor (1); a fuel supply device (19) that supplies fuel to the combustor (1); an air supply device (9) that supplies combustion air to the combustor (1); an exhaust gas flow path (3) through which exhaust gas flows from the combustor (1); a CO detector (4) that detects CO in the exhaust gas; a temperature detector (6) that detects the temperature of the exhaust gas; and a controller (7) which, when exhaust gas is flowing in the exhaust gas flow path, detects an exhaust gas flow path (3) error on the basis of the change in the temperature detected by the temperature detector (6) with respect to the change in the amount of heating of the exhaust gas by a heater, and/or detects an exhaust gas flow path (3) error on the basis of the change in the temperature detected by the temperature detector (6) with respect to the change in the output of the fuel supply device (19) and/or the air supply device (9).
