Mixing arrangement for mixing fuel with a stream of oxygen containing gas

The invention relates to a mixing arrangement for mixing a fuel (13, 15) with a stream of oxygen containing gas flowing along an axis (16) in an axial channel, especially in the second combustor of a gas turbine with sequential combustion. The mixing is improved and the mixing length reduced by said mixing arrangement comprising an injector (10) with at least one injector ring (11), which is passed by said stream of gas inside and outside.
