Method for active suppression of hydrodynamic instabilities in a combustion system and a combustion system for carrying out the method

摘要

A method for active suppression of hydrodynamic instabilities in a combustion system in which liquid or gaseous fuel is premixed with combustion air and the fuel/air mixture is then burnt. The mass flow of the supplied fuel is modulated on the basis of a selected time function. Simplification and increased functional reliability are achieved by the modulation which is carried out using fluidics.
