A system and method for controlling combustion dynamics by acoustically controlling / suppressing fuel flow variations at a fuel injection location

摘要

A system for controlling the combustion dynamics of land-based or aircraft gas turbines uses an acoustic driver (50) which is adapted to bring pressure disturbances across a premixed fuel injection port (52) to substantially zero in response to a control signal so that Disturbances in the flow of fuel across the fuel injection port (52) are essentially zero.
