Safety Analysis on Combustion Mode of S109FA-SS Combined Cycle Units

To solve the problem of high maintenance expense of gas turbine unit caused by frequent start/stop,the way by reasonably choosing start/stop mode to reduce the frequency of component damage is proposed.Meanwhile,an introduction is being presented to the combustion mode and fuel control of GE S109FA-SS gas turbine,while a safety analysis made to the burners at different combustion modes,with countermeasures for elongating the service life of combustion chambers put forward.
