摘要： A combustion system includes a combustor having staging blocks and flashback detection units configured to detect flashbacks occurring in the staging blocks, and a combustion control device configured to stop a supply of a fuel for one of the staging blocks in which a flashback occurs based on a detection signal from one of the flashback detection units. The combustion control device includes a staging processing unit configured to instruct to supply the fuel or stop the supply of the fuel for each of the staging blocks based on a staging pattern in which an operating line is specified and a load adjustment unit configured to reduce an amount of load to a level at which the supply of the fuel for the one of the staging blocks is stopped when the detection signal is input from the one of the flashback detection units.

摘要： A gas turbine combustor is provided with a combustor basket where combustion gas flows, the combustion gas being produced by combustion of fuel injected from a nozzle, and a first resonance device and a second resonance device mounted on an outer surface of the combustor basket. The second resonance device is disposed on a downstream side from the first resonance device in a flow of the combustion gas and damps combustion oscillation of a frequency higher than the first resonance device. The first and second resonance devices are acoustic liners each having a housing mounted to the outer surface of the combustor basket. A resonance space surrounded by the housing and the outer surface of the combustor basket communicates with an interior space of the combustor basket via a plurality of acoustic holes formed in the combustor basket.
