Patent ID: 6840046

Claim:
A method for minimizing a pressure amplitude of thermoacoustic vibrations in a combustion system, the method comprising: measuring a pressure in the combustion system; feeding a first quantity of fuel through a first fuel line in a pulsating process based on the measured pressure in the combustion system where feeding the first quantity of fuel to the first fuel line minimizes the pressure amplitude of thermoacoustic vibrations; feeding a second quantity of fuel through a second fuel line in a pulsating process based on the measured pressure in the combustion system where feeding the second quantity of fuel to the second fuel line minimizes the pressure amplitude of thermoacoustic vibrations; and completing a modulation period, the modulation period including the feeding of the first quantity of fuel and the feeding of the second quantity of fuel wherein a pulse of the pulsating process is limited with respect to both time and subsequent feeding of the second quantity of fuel.
