Detailed investigations of different liquid fuel injectors for the main stage of a lean burnner were carried out. The main injector follows a jet in cross flow arrangement. Two other concepts with a prefilmer and trailing edge injection were additionally derived. It was found that the fuel split between main and pilot injector has a significant influence on flame structure. Low NOx emissions are observed with main burners with a low fuel penetration into the central recirculation zone.
