Abstract
Official abstract text for this publication.
This invention relates to a lean premix burner of a gas-turbine engine with an annular central body 2 , which, while being essentially concentric to a burner center axis 1 , is connected to a film applicator 3 , which conically widens at the fuel exit side, as well as to an outer ring 4 concentrically arranged to the burner center axis 1 and surrounding at least the film applicator 3 at a certain distance, characterized in that an annular flow-guiding element 6 is provided in an annular duct 5 formed between the outer ring 4 and the film applicator 3 which, in the axial direction of the annular duct 5 , is at least partly situated outside of the outer ring 4.
First claim
Opening claim text (preview).
What is claimed is: 1. A lean premix burner of a gas-turbine engine, comprising: an annular central body being essentially concentric to a burner center axis, a film applicator having a conical film application surface for supplying with fuel from a fuel exit opening, the film application surface having a fuel flow off edge at a downstream area; the film application surface conically widening between a conical surface upstream of the fuel exit opening and to the fuel flow off ed…
