Abstract: PROBLEM TO BE SOLVED: To provide a combustor for especially driving a gas turbine in which instability of combustion can be suppressed while keeping a simple and reliable function by improving a combustor of such a type as having a large number of burners of identical thermal power output working in common combustion chambers in parallel with the axis. SOLUTION: A large number of burners 12, 13, 14, 15 are arranged differently such that flames 24, 25, 26, 27 produced therefrom or the flame fronts thereof are positioned to be distributed along the axis 28.

Abstract: In the fuel feed pipes (17,18) to the fuel injectors (15,16) resonance chambers (20,21) are located. This provides the injectors with different acoustic impedances which, in relation to the acoustic signal outside the injectors, results in a difference in phase of the fluctuations in the fuel mass flow
