Abstract (en)

[origin: EP2003399A2] The chamber (202) has an air inlet opening emerging from a combustion hearth, and an outer wall (214) with pilot cavities (222), where each cavity is extended between wall's longitudinal upstream and downstream ends and radially towards the wall's exterior. The cavities are supplied by air exterior to the chamber along circumferential direction. A fuel injection system (220) has pilot injectors (220a) circumferentially alternating with open gas injectors (220b), where each injector (220a) is radially emerged in one cavity. Each injector (220b) is radially emerged between adjacent cavities.
