Abstract:
A combustion chamber device, including a combustion chamber and a set of burners which each has an outlet opening in the combustion chamber,wherein each burner includes members for the supply of a flow of an oxygen-containing gas to the burner, members for the supply of a fuel to the burner and a space, which extends to the combustion chamber along a longitudinal direction and is arranged to enable mixing of the supplied fuel and the supplied oxygen-containing gas, wherein each burner is arranged to convey a substantially equally great flow of oxygen-containing gas through the burner to the combustion chamber, wherein each burner is defined by at least one parameter which includes a characteristic length of the space along the longitudinal direction, and wherein the characteristic length of at least one of said burners is selected in such a way that it deviates from the corresponding length of another burner in said set and in such a way that the influence of the oscillations which arise during operation of the combustion chamber device are reduced.
