Abstract: In a premix supply, for supplying a fuel and oxidizer gas into a combustion chamber for burning, the premix supply having a smaller diameter flow than the combustion chamber, the premix supply comprising at least one dielectric barrier discharge device (DBD) comprising two electrodes separated by a dielectric, improved flame stability limits may be provided for the adjacent combustor by the actuation of the DBD to induce ionic wind. Both electrodes may be provided in a single wall of the premix supply. The two electrodes may be arranged substantially upstream and downstream of each other. The electrodes may be arranged to generate an ionic wind preferentially directed in a direction of flow through the premix supply.
