A burner assembly for a firing system for firing fluidic fuels is provided. The burner assembly has a burner hub, an air inlet channel and a fuel inlet channel, wherein the fuel inlet channel is at least partially designed in the burner hub. A screening wall is arranged in the fuel inlet channel. The screening wall is spaced apart from a wall of the fuel inlet channel so that an intermediate space is formed between the wall of the fuel inlet channel and the screening wall. A sleeve is equipped with at least one radial positioning means that ensures a clearance of the sleeve from the wall of the fuel inlet channel. The at least one radial positioning means of the sleeve is designed as a positioning projection arranged in a circular manner, protruding out radially.

Shielding wall for a fuel supply duct in a turbine engine

A gas turbine engine () includes a cylindrical basket () having an axis () and a single main burner assembly () disposed within the basket. A burner insert () is disposed in an annular space between the burner assembly and the basket. The insert includes a face perpendicular to the axis of the basket. A plurality of passageways () are formed in the basket, positioned proximate to and downstream of the burner insert for allowing passage of a portion of an oxidizer flow () into a combustion chamber (). A fluid flow path (), defined between a combustion chamber liner portion () of the basket and a casing () spaced radially outward from the combustion liner portion, discharges a fluid into a flow reversal region () proximate an inlet () of the burner assembly. A fuel outlet () is disposed in the flow reversal region.

Gas turbine can annular combustor

The invention relates to a pre-mix burner with a main burner and a pilot burner, for stabilization of the main burner. The pilot burner comprises a fine-pored burner material, which permits a combustion with low nitrogen oxide content, which is not susceptible to combustion variations.
