Abstract: The invention refers to a combustion chamber device including a combustion chamber (2) and a set of burners (6) with an outlet opening (7) in the combustion chamber. Each burner includes members (10) for the supply of a flow of oxygen-containing gas, members (8) for the supply of fuel, and a space (9), which extends to the combustion chamber (2) for mixing of the fuel and the oxygen-containing gas. Each burner (6) is arranged to convey a substantially equally large flow of oxygen-containing gas through the burner to the combustion chamber. Each burner (6) is defined by at least one parameter including a characteristic length (a) of the space (9) along the longitudinal direction (x). At least the characteristic length (a) of at least one of the burners is selected in such a way that it deviates from the corresponding length (a) of another burner and in such a way that the influence of the oscillations which arise during operation of the combustion chamber device are reduced.

Abstract: A method for starting a burner device for a gas turbine, where the burner device comprises at least one burner member (5), arranged to be supplied with a liquid fuel, and an ignition member (9), which is activated for igniting a fuel which is supplied to the burner member (5). The fuel which initially is supplied to the burner member (5) and which is ignited by means of the ignition member and generates a burner member flame mainly comprises an ignition gas.
