Abstract
An apparatus for mixing gaseous fuel and air for combustion, particularly premixing-type combustion in a gas turbine, has a conduit providing a passage for flow of the air with a reverse bend defined by opposed first and second wall portions that bound respectively the outside and the inside of said reverse bend as seen in a longitudinal section. The reverse bend establishes a flow region of air having a velocity gradient extending transversely across the conduit from a high velocity zone adjacent the first side wall portion at the outside of the reverse bend to a low velocity zone. Injection means for the gaseous fuel injects the fuel from the first side wall portion into the high velocity zone with a velocity component transverse to the air flow and in a direction towards the low velocity zone. Rapid and uniform mixing is obtained.
