Abstract:

Gas turbine combustion oscillation is a key and unavoidable problem in premixed combustion technology. The mechanism of combustion pressure fluctuation is the basis for solving this problem. Analysis and measurement on combustion pressure fluctuation is an effective supplement for the basic experiment. The mechanism of gas turbine combustion pressure fluctuation is analyzed with combustion mechanism, simple feedback model, openloop gain and Bode plot. Considering the location of pressure transducers and the type of transducers, the key technologies for combustion pressure fluctuation measurement and  typical measurement procedures are introduced.
