Abstract

A device for igniting a combustion in a combustion chamber of a gas turbine has a housing fitted with an end piece and with a head piece. Hitherto, an ignition conductor comes into contact with combustion air. Moreover, fragments of a partial ceramic insulation can lead to damage. To improve the quality of ignition, the ignition conductor and a gas conduit are disposed to run parallel to one another within a housing. The ignition conductor is surrounded by a protective sleeve, and an annular space between the ignition conductor and the protective sleeve is filled completely with a ceramic material. An annular disc serving as an ignition electrode is mounted on that end of the protective sleeve that projects into the head piece.
