Abstract (en)
A premix burner for a gas turbine for use in power generation plants, comprises an axial swirler (12) to which pilot fuel gas and pilot air flow are delivered, and a duct for the premix flow (9) extending annularly and diagonally around said axial swirler (12), which contains a diagonal swirler (8) to which premix fuel gas and premix air are delivered. The axial swirler and diagonal swirler converge substantially at the outlet section (16) of the burner. A discharge throat (15) is attached to the outlet of the axial swirler (12) and extends axially from the outlet section (16) of the burner within the combustion chamber (14). The presence of the discharge throat contributes significantly towards improving the working stability at high and medium loads of the burners in Siemens gas turbine machines of the VX4 type.
