Abstract
The burner () for a gas turbine includes a duct () housing a plurality of tetrahedron shaped vortex generators () and a lance () to inject a fuel to be combusted. Within the duct (), a plurality of vortex generators () are provided with a plurality of holes () for injecting cooling air. The cooling holes () define passing through areas that are non-uniformly distributed on a top wall () of the vortex generators (). A method for locally cooling a hot gases flow passing through a burner includes non-uniformly injecting cooling air from a vortex generator into the hot gas flow in the duct, which can reduce the occurrence of flashback in the burner.
