Device for fastening a sequentially operated burner in a gas turbine arrangement

Abstract

A device for fastening a second burner (SEV burner) () in a sequentially operated gas turbine arrangement, in which a fuel/air mixture is burnt in a first burner, so as to form hot gases which can subsequently be supplied, partly expanded, for a second combustion to the SEV burner (), in which the burner is designed essentially as a flow duct, with a flow duct wall, which has an orifice (), through which a fuel supply () can be introduced into the interior of the SEV burner (), and on which are provided in the axial direction of the orifice (), in each case opposite one another, two fastening structures (), into which in each case a carrying structure for the further fastening of the SEV burner () to an external carrier () can be introduced. The carrying structure includes a unitary carrier plate () on which countercontours for fastening to the two fastening structures () lying opposite the orifice () are provided and which provides a recess which corresponds at least to the size of the orifice () in the flow duct wall, so that, in the state fastened to the external carrier (), the carrier plate () does not cover the orifice () of the flow duct wall.
