Abstract
A method for detecting combustion conditions in a plurality of combustors in a gas-turbine apparatus which includes the combustors and a gas turbine driven by combustion gas from the combustors, comprises a step for measuring concentration of unburnt component in the combustion gas by means of a plurality of sensors disposed on the downstream side of the gas turbine, a step for obtaining a distribution pattern of the measured concentration, and a step for investigating the distribution pattern to detect combustion conditions in the combustors.
