ABSTRACT:
A sealing arrangement designed to seal an opening in a flame tube wall into which an igniter and a fuel spray device mounted on a casing extend. The sealing arrangement comprises a first plate having a first aperture therein through which the fuel spray device extends with clearance and a grommet defining a second aperture through which the igniter extends to locate the first plate, and a second plate having a grommet defining a first aperture through which the fuel spray device extends to locate the second plate and a second aperture through which the igniter extends with clearance. The plates are relatively movable so as to permit relative axial and radial movement between the flame tube and the fuel spray device and the igniter caused by thermal expansion.
