Abstract
A flange () for optical flame observation in a gas turbine includes at least one bore for optical observation, in which bore there is arranged at least one pane () for separating the flame-side space, which is in substantially direct communication with a combustion chamber in which the at least one flame that is to be monitored is arranged, from the outside space, from which the observation of the at least one flame can take place. In a flange () of this type, fogging of the at least one pane () is made possible in a simple manner which can be guaranteed over a prolonged period of time by virtue of the fact that two panes (), which delimit a sealed intermediate space () in the bore for optical observation, are arranged one behind the other with respect to the optical axis (), and that a device () for dehumidifying the sealed intermediate space () is includes.
