Fuel injector swirler arrangement having a shield means for creating fuel rich pockets in gas-or liquid-fuelled turbine

The arrangement comprises a swirler for producing at least one air stream for mixing with a supply of fuel but wherein the supply of fuel is initially injected into at least one zone adjacent a respective air stream but shielded (by 26) therefrom whereby fuel-rich pockets of fluid are formed in the...

Beschreibung
Zusammenfassung:	The arrangement comprises a swirler for producing at least one air stream for mixing with a supply of fuel but wherein the supply of fuel is initially injected into at least one zone adjacent a respective air stream but shielded (by 26) therefrom whereby fuel-rich pockets of fluid are formed in the zone(s). The pockets ensure flame stability at least at lower power settings. The zone is defined by a wall of the swirler. The fuel is injected through nozzles. Additional nozzles for supplementary supply of fuel may be provided in a block. A plate is arranged between the block and the swirler.
