Abstract:
1. An SEV burner fastenable in a sequentially operated gas turbine arrangement, in which arrangement a fuel/air mixture can be burned in a first burner to form hot gases which can subsequently be supplied, partly expanded, for a second combustion to the SEV burner, the SEV burner comprising: a flow duct wall defining a flow duct; an orifice formed in the flow duct wall through which a fuel supply can be introduced into the flow duct; two fastening structures protruding from the flow duct wall positioned axially adjacent to the orifice and opposite one another; and a carrying structure configured and arranged to cooperate with the two fastening structures to fasten the burner to an external carrier; wherein the carrying structure comprises a unitary carrier plate including elements complementary to the two fastening structures arranged to slidingly engage with and fasten to the two fastening structures, and a recess which corresponds at least to the size of the orifice in the flow duct wall, so that, when fastened to the external carrier, the carrier plate does not cover the orifice of the flow duct wall; wherein the SEV burner is sequentially mounted after a first burner.
