Abstract

A fuel injector 12 for a gas turbine includes a plurality of tubes 13 in close proximity to one another, each tube having a fuel admission aperture 14 adjacent its upstream end, fuel passing through the apertures via fuel passages 21b situated in the spaces between the air passages. The fuel is supplied to a plenum 16 by a conduit 15 and flows between the tubes and into apertures 14 to be mixed with air flowing through the tubes. The tubes may be replaced by square rods (30) Fig. 5a (not shown) having air passages (34) connected to a fuel passage (31). <IMAGE>
