Abstract (en)

[origin: EP2423597A2] The premix burner (10) has a series of linear holes running transverse to a flow direction of combustion air (20). The linear holes are arranged at outer walls of air inlet channels (18, 19) by injection openings (21). Gaseous fuel (22) is injected into the combustion air that flows transverse to the flow direction via the injection openings. The openings exhibit ratio of diameter of the injection openings to effective outlet diameter of the burner, where the ratio ranges between 0.011 and 0.015. Distance between the openings is of about 16 mm. An independent claim is also included for a method for refinishing a premix burner for a gas turbine.
